thumb|The lantern room of the Cordouan Lighthouse, in which the first Fresnel lens entered service in 1823. The current fixed catadioptric "beehive" lens replaced Fresnel's original rotating lens in 1854.
Within a century of Fresnel's initial stepped-lens proposal, more than 10,000 lights with Fresnel lenses were protecting lives and property around the world.Levitt, 2013, p. 19. Concerning the other benefits, the science historian Theresa H. Levitt has remarked:
In the history of physical optics, Fresnel's successful revival of the wave theory nominates him as the pivotal figure between Newton, who held that light consisted of corpuscles, and James Clerk Maxwell, who established that light waves are electromagnetic. Whereas Albert Einstein described Maxwell's work as "the most profound and the most fruitful that physics has experienced since the time of Newton," commentators of the era between Fresnel and Maxwell made similarly strong statements about Fresnel:
MacCullagh, as early as 1830, wrote that Fresnel's mechanical theory of double refraction "would do honour to the sagacity of Newton".
Lloyd, in his Report on the progress and present state of physical optics (1834) for the British Association for the Advancement of Science, surveyed previous knowledge of double refraction and declared:The theory of Fresnel to which I now proceed,—and which not only embraces all the known phenomena, but has even outstripped observation, and predicted consequences which were afterwards fully verified,—will, I am persuaded, be regarded as the finest generalization in physical science which has been made since the discovery of universal gravitation.Lloyd, 1834, p. 382.In 1841, Lloyd published his Lectures on the Wave-theory of Light, in which he described Fresnel's transverse-wave theory as "the noblest fabric which has ever adorned the domain of physical science, Newton's system of the universe alone excepted."
William Whewell, in all three editions of his History of the Inductive Sciences (1837, 1847, and 1857), at the end of Book , compared the histories of physical astronomy and physical optics and concluded:It would, perhaps, be too fanciful to attempt to establish a parallelism between the prominent persons who figure in these two histories. If we were to do this, we must consider Huyghens and Hooke as standing in the place of Copernicus, since, like him, they announced the true theory, but left it to a future age to give it development and mechanical confirmation; Malus and Brewster, grouping them together, correspond to Tycho Brahe and Kepler, laborious in accumulating observations, inventive and happy in discovering laws of phenomena; and Young and Fresnel combined, make up the Newton of optical science.Whewell, 1857, pp. 370–371.
What Whewell called the "true theory" has since undergone two major revisions. The first, by Maxwell, specified the physical fields whose variations constitute the waves of light. Without the benefit of this knowledge, Fresnel managed to construct the world's first coherent theory of light, showing in retrospect that his methods are applicable to multiple types of waves. The second revision, initiated by Einstein's explanation of the photoelectric effect, supposed that the energy of light waves was divided into quanta, which were eventually identified with particles called photons. But photons did not exactly correspond to Newton's corpuscles; for example, Newton's explanation of ordinary refraction required the corpuscles to travel faster in media of higher refractive index, which photons do not. Neither did photons displace waves; rather, they led to the paradox of wave–particle duality. Moreover, the phenomena studied by Fresnel, which included nearly all the optical phenomena known at his time, are still most easily explained in terms of the wave nature of light. So it was that, as late as 1927, the astronomer Eugène Michel Antoniadi declared Fresnel to be "the dominant figure in optics." |

Abbot | short description | thumb|upright|St. Dominic of Silos enthroned as abbot (Hispano-Flemish Gothic 15th century)
Abbot is an ecclesiastical title given to the head of an independent monastery for men in various Western Christian traditions. The name is derived from abba, the Aramaic form of the Hebrew ab, and means "father".Thomas Oesterreich, Abbot, in The Catholic Encyclopedia. Vol. 1. New York: Robert Appleton Company, 1907. The female equivalent is abbess. |
Abbot | Origins | Origins
The title had its origin in the monasteries of Egypt and Syria, spread through the eastern Mediterranean, and soon became accepted generally in all languages as the designation of the head of a monastery. The word is derived from the Aramaic meaning "father" or , meaning "my father" (it still has this meaning in contemporary Hebrew: אבא and Aramaic: ܐܒܐ) In the Septuagint, it was written as "abbas". At first it was employed as a respectful title for any monk, but it was soon restricted by canon law to certain priestly superiors. At times it was applied to various priests, e.g. at the court of the Frankish monarchy the ("of the palace"') and ("of the camp") were chaplains to the Merovingian and Carolingian sovereigns' court and army respectively. The title of abbot came into fairly general use in western monastic orders whose members include priests. |

An abbot (from , , from ("father"), from (), from / (, "father"); compare ; ) is the head and chief governor of a community of monks, called also in the East hegumen or archimandrite. The English version for a female monastic head is abbess. |
Abbot | Early history | Early history
In Egypt, the first home of monasticism, the jurisdiction of the abbot, or archimandrite, was but loosely defined. Sometimes he ruled over only one community, sometimes over several, each of which had its own abbot as well. Saint John Cassian speaks of an abbot of the Thebaid who had 500 monks under him. By the Rule of St Benedict, which, until the Cluniac reforms, was the norm in the West, the abbot has jurisdiction over only one community. The rule, as was inevitable, was subject to frequent violations; but it was not until the foundation of the Cluniac Order that the idea of a supreme abbot, exercising jurisdiction over all the houses of an order, was definitely recognised.
Monks, as a rule, were laymen, nor at the outset was the abbot any exception. For the reception of the sacraments, and for other religious offices, the abbot and his monks were commanded to attend the nearest church. This rule proved inconvenient when a monastery was situated in a desert or at a distance from a city, and necessity compelled the ordination of some monks. This innovation was not introduced without a struggle, ecclesiastical dignity being regarded as inconsistent with the higher spiritual life, but, before the close of the 5th century, at least in the East, abbots seem almost universally to have become deacons, if not priests. The change spread more slowly in the West, where the office of abbot was commonly filled by laymen till the end of the 7th century. The ecclesiastical leadership exercised by abbots despite their frequent lay status is proved by their attendance and votes at ecclesiastical councils. Thus at the first Council of Constantinople, AD 448, 23 archimandrites or abbots sign, with 30 bishops.
The second Council of Nicaea, AD 787, recognized the right of abbots to ordain their monks to the inferior orders below the diaconate, a power usually reserved to bishops.
Abbots used to be subject to episcopal jurisdiction, and continued generally so, in fact, in the West till the 11th century. The Code of Justinian (lib. i. tit. iii. de Ep. leg. xl.) expressly subordinates the abbot to episcopal oversight. The first case recorded of the partial exemption of an abbot from episcopal control is that of Faustus, abbot of Lerins, at the council of Arles, AD 456; but the exorbitant claims and exactions of bishops, to which this repugnance to episcopal control is to be traced, far more than to the arrogance of abbots, rendered it increasingly frequent, and, in the 6th century, the practice of exempting religious houses partly or altogether from episcopal control, and making them responsible to the pope alone, received an impulse from Pope Gregory the Great. These exceptions, introduced with a good object, had grown into a widespread evil by the 12th century, virtually creating an imperium in imperio, and depriving the bishop of all authority over the chief centres of influence in his diocese. |
Abbot | Later Middle Ages | Later Middle Ages
In the 12th century, the abbots of Fulda claimed precedence of the archbishop of Cologne. Abbots more and more assumed almost episcopal state, and in defiance of the prohibition of early councils and the protests of St Bernard and others, adopted the episcopal insignia of mitre, ring, gloves and sandals.
It has been maintained that the right to wear mitres was sometimes granted by the popes to abbots before the 11th century, but the documents on which this claim is based are not genuine (J. Braun, Liturgische Gewandung, p. 453). The first undoubted instance is the bull by which Alexander II in 1063 granted the use of the mitre to Egelsinus, abbot of the monastery of St Augustine at Canterbury. The mitred abbots in England were those of Abingdon, St Alban's, Bardney, Battle, Bury St Edmunds, St Augustine's Canterbury, Colchester, Croyland, Evesham, Glastonbury, Gloucester, St Benet's Hulme, Hyde, Malmesbury, Peterborough, Ramsey, Reading, Selby, Shrewsbury, Tavistock, Thorney, Westminster, Winchcombe, and St Mary's York.Government in Church and State from University of Wisconsin-Madison retrieved 15 June 2013 Of these the precedence was yielded to the abbot of Glastonbury, until in AD 1154 Adrian IV (Nicholas Breakspear) granted it to the abbot of St Alban's, in which monastery he had been brought up. Next after the abbot of St Alban's ranked the abbot of Westminster and then Ramsey. Elsewhere, the mitred abbots that sat in the Estates of Scotland were of Arbroath, Cambuskenneth, Coupar Angus, Dunfermline, Holyrood, Iona, Kelso, Kilwinning, Kinloss, Lindores, Paisley, Melrose, Scone, St Andrews Priory and Sweetheart. pp. 67-97 To distinguish abbots from bishops, it was ordained that their mitre should be made of less costly materials, and should not be ornamented with gold, a rule which was soon entirely disregarded, and that the crook of their pastoral staff (the crosier) should turn inwards instead of outwards, indicating that their jurisdiction was limited to their own house.
The adoption of certain episcopal insignia (pontificalia) by abbots was followed by an encroachment on episcopal functions, which had to be specially but ineffectually guarded against by the Lateran council, AD 1123. In the East abbots, if in priests' orders and with the consent of the bishop, were, as we have seen, permitted by the second Nicene council, AD 787, to confer the tonsure and admit to the order of reader; but gradually abbots, in the West also, advanced higher claims, until we find them in AD 1489 permitted by Innocent IV to confer both the subdiaconate and diaconate. Of course, they always and everywhere had the power of admitting their own monks and vesting them with the religious habit.
The power of the abbot was paternal but absolute, limited, however, by the canon law. One of the main goals of monasticism was the purgation of self and selfishness, and obedience was seen as a path to that perfection. It was sacred duty to execute the abbot's orders, and even to act without his orders was sometimes considered a transgression. Examples among the Egyptian monks of this submission to the commands of the superiors, exalted into a virtue by those who regarded the entire crushing of the individual will as a goal, are detailed by Cassian and others, e.g. a monk watering a dry stick, day after day, for months, or endeavoring to remove a huge rock immensely exceeding his powers. |
Abbot | Appointments | Appointments
When a vacancy occurred, the bishop of the diocese chose the abbot out of the monks of the monastery, but the right of election was transferred by jurisdiction to the monks themselves, reserving to the bishop the confirmation of the election and the benediction of the new abbot. In abbeys exempt from the archbishop's diocesan jurisdiction, the confirmation and benediction had to be conferred by the pope in person, the house being taxed with the expenses of the new abbot's journey to Rome. It was necessary that an abbot should be at least 30 years of age, of legitimate birth, a monk of the house for at least 10 years, unless it furnished no suitable candidate, when a liberty was allowed of electing from another monastery, well instructed himself, and able to instruct others, one also who had learned how to command by having practised obedience. In some exceptional cases an abbot was allowed to name his own successor. Cassian speaks of an abbot in Egypt doing this; and in later times we have another example in the case of St Bruno. Popes and sovereigns gradually encroached on the rights of the monks, until in Italy the pope had usurped the nomination of all abbots, and the king in France, with the exception of Cluny, Premontré and other houses, chiefs of their order. The election was for life, unless the abbot was canonically deprived by the chiefs of his order, or when he was directly subject to them, by the pope or the bishop, and also in England it was for a term of 8–12 years.
The ceremony of the formal admission of a Benedictine abbot in medieval times is thus prescribed by the consuetudinary of Abingdon. The newly elected abbot was to put off his shoes at the door of the church, and proceed barefoot to meet the members of the house advancing in a procession. After proceeding up the nave, he was to kneel and pray at the topmost step of the entrance of the choir, into which he was to be introduced by the bishop or his commissary, and placed in his stall. The monks, then kneeling, gave him the kiss of peace on the hand, and rising, on the mouth, the abbot holding his staff of office. He then put on his shoes in the vestry, and a chapter was held, and the bishop or his delegate preached a suitable sermon. |
Abbot | General information | General information
Before the late modern era, the abbot was treated with the utmost reverence by the brethren of his house. When he appeared either in church or chapter all present rose and bowed. His letters were received kneeling, as were those of the pope and the king. No monk might sit in his presence, or leave it, without his permission, reflecting the hierarchical etiquette of families and society. The highest place was assigned to him, both in church and at table. In the East he was commanded to eat with the other monks. In the West, the Rule of St Benedict appointed him a separate table, at which he might entertain guests and strangers. Because this permission opened the door to luxurious living, Synods of Aachen decreed that the abbot should dine in the refectory, and be content with the ordinary fare of the monks, unless he had to entertain a guest. These ordinances proved, however, generally ineffective to secure strictness of diet, and contemporaneous literature abounds with satirical remarks and complaints concerning the inordinate extravagance of the tables of the abbots. When the abbot condescended to dine in the refectory, his chaplains waited upon him with the dishes, a servant, if necessary, assisting them. When abbots dined in their own private hall, the Rule of St Benedict charged them to invite their monks to their table, provided there was room, on which occasions the guests were to abstain from quarrels, slanderous talk and idle gossiping.

The ordinary attire of the abbot was according to rule to be the same as that of the monks. But by the 10th century the rule was commonly set aside, and we find frequent complaints of abbots dressing in silk, and adopting sumptuous attire. Some even laid aside the monastic habit altogether, and assumed a secular dress. With the increase of wealth and power, abbots had lost much of their special religious character, and become great lords, chiefly distinguished from lay lords by celibacy. Thus we hear of abbots going out to hunt, with their men carrying bows and arrows; keeping horses, dogs and huntsmen; and special mention is made of an abbot of Leicester , c. 1360, who was the most skilled of all the nobility in hare hunting. In magnificence of equipage and retinue the abbots vied with the first nobles of the realm. They rode on mules with gilded bridles, rich saddles and housings, carrying hawks on their wrist, followed by an immense train of attendants. The bells of the churches were rung as they passed. They associated on equal terms with laymen of the highest distinction, and shared all their pleasures and pursuits. This rank and power was, however, often used most beneficially. For instance, we read of Richard Whiting, the last abbot of Glastonbury, judicially murdered by Henry VIII, that his house was a kind of well-ordered court, where as many as 300 sons of noblemen and gentlemen, who had been sent to him for virtuous education, had been brought up, besides others of a lesser rank, whom he fitted for the universities. His table, attendance and officers were an honour to the nation. He would entertain as many as 500 persons of rank at one time, besides relieving the poor of the vicinity twice a week. He had his country houses and fisheries, and when he travelled to attend parliament his retinue amounted to upwards of 100 persons. The abbots of Cluny and Vendôme were, by virtue of their office, cardinals of the Roman church.
In the process of time, the title abbot was extended to clerics who had no connection with the monastic system, as to the principal of a body of parochial clergy; and under the Carolingians to the chief chaplain of the king, , or military chaplain of the emperor, It even came to be adopted by purely secular officials. Thus the chief magistrate of the republic at Genoa was called .
Lay abbots (M. Lat. , , , , or , , or sometimes simply ) were the outcome of the growth of the feudal system from the 8th century onwards. The practice of commendation, by which—to meet a contemporary emergency—the revenues of the community were handed over to a lay lord, in return for his protection,
early suggested to the emperors and kings the expedient of rewarding their warriors with rich abbeys held in commendam.
During the Carolingian epoch, the custom grew up of granting these as regular heritable fiefs or benefices, and by the 10th century, before the great Cluniac reform, the system was firmly established. Even the abbey of St Denis was held in commendam by Hugh Capet. The example of the kings was followed by the feudal nobles, sometimes by making a temporary concession permanent, sometimes without any form of commendation whatever. In England the abuse was rife in the 8th century, as may be gathered from the acts of the council of Cloveshoe. These lay abbacies were not merely a question of overlordship, but implied the concentration in lay hands of all the rights, immunities and jurisdiction of the foundations, i.e. the more or less complete secularization of spiritual institutions. The lay abbot took his recognized rank in the feudal hierarchy, and was free to dispose of his fief as in the case of any other. The enfeoffment of abbeys differed in form and degree. Sometimes the monks were directly subject to the lay abbot; sometimes he appointed a substitute to perform the spiritual functions, known usually as dean (), but also as abbot (, , ).
When the great reform of the 11th century had put an end to the direct jurisdiction of the lay abbots, the honorary title of abbot continued to be held by certain of the great feudal families, as late as the 13th century and later, with the head of the community retaining the title of dean. The connection of the lesser lay abbots with the abbeys, especially in the south of France, lasted longer; and certain feudal families retained the title of () for centuries, together with certain rights over the abbey lands or revenues. The abuse was not confined to the West. John, patriarch of Antioch at the beginning of the 12th century, informs us that in his time most monasteries had been handed over to laymen, , for life, or for part of their lives, by the emperors.
Giraldus Cambrensis reported (Itinerary, ii.iv) the common customs of lay abbots in the late 12th-century Church of Wales:
In conventual cathedrals, where the bishop occupied the place of the abbot, the functions usually devolving on the superior of the monastery were performed by a prior. |
Abbot | Modern practices | Modern practices
In the Roman Catholic Church, abbots continue to be elected by the monks of an abbey to lead them as their religious superior in those orders and monasteries that make use of the term (some orders of monks, as the Carthusians for instance, have only priors). A monastery must have been granted the status of an abbey by the pope, and such monasteries are normally raised to this level after showing a degree of stability—a certain number of monks in vows, a certain number of years of establishment, a certain firmness to the foundation in economic, vocational and legal aspects. Prior to this, the monastery would be a mere priory, headed by a prior who acts as superior but without the same degree of legal authority that an abbot has.

The abbot is chosen by the monks from among the fully professed monks. Once chosen, he must request blessing: the blessing of an abbot is celebrated by the bishop in whose diocese the monastery is or, with his permission, another abbot or bishop. The ceremony of such a blessing is similar in some aspects to the consecration of a bishop, with the new abbot being presented with the mitre, the ring, and the crosier as symbols of office and receiving the laying on of hands and blessing from the celebrant. Though the ceremony installs the new abbot into a position of legal authority, it does not confer further sacramental authority- it is not a further degree of Holy Orders (although some abbots have been ordained to the episcopacy).
Once he has received this blessing, the abbot not only becomes father of his monks in a spiritual sense, but their major superior under canon law, and has the additional authority to confer the ministries of acolyte and lector (formerly, he could confer the minor orders, which are not sacraments, that these ministries have replaced). The abbey is a species of "exempt religious" in that it is, for the most part, answerable to the pope, or to the abbot primate, rather than to the local bishop.
The abbot wears the same habit as his fellow monks, though by tradition he adds to it a pectoral cross.
Territorial abbots follow all of the above, but in addition must receive a mandate of authority from the pope over the territory around the monastery for which they are responsible. |
Abbot | Abbatial hierarchy | Abbatial hierarchy
In some monastic families, there is a hierarchy of precedence or authority among abbots. In some cases, this is the result of an abbey being considered the "mother" of several "daughter" abbeys founded as dependent priories of the "mother". In other cases, abbeys have affiliated in networks known as "congregations". Some monastic families recognize one abbey as the motherhouse of the entire order.
The abbot of Sant'Anselmo di Aventino, in Rome, is styled the "abbot primate", and is acknowledged the senior abbot for the Order of Saint Benedict.
An abbot-president is the head of a congregation (federation) of abbeys within the Order of Saint Benedict (for instance, the English Congregation, the American-Cassinese Congregation, etc.), or of the Cistercians
An archabbot is the head of some monasteries which are the motherhouses of other monasteries (for instance, Saint Vincent Archabbey, Latrobe, Pennsylvania)

Abbot | Modern abbots not as superior | Modern abbots not as superior
The title abbé (French; Ital. abate), as commonly used in the Catholic Church on the European continent, is the equivalent of the English "Father" (parallel etymology), being loosely applied to all who have received the tonsure. This use of the title is said to have originated in the right conceded to the king of France, by the concordat between Pope Leo X and Francis I (1516), to appoint commendatory abbots () to most of the abbeys in France. The expectation of obtaining these sinecures drew young men towards the church in considerable numbers, and the class of abbés so formed they were sometimes called, and sometimes (ironically) ("abbés of holy hope; or in a jeu de mots, "of St. Hope")came to hold a recognized position. The connection many of them had with the church was of the slenderest kind, consisting mainly in adopting the title of abbé, after a remarkably moderate course of theological study, practising celibacy and wearing distinctive dress, a short dark-violet coat with narrow collar. Being men of presumed learning and undoubted leisure, many of the class found admission to the houses of the French nobility as tutors or advisers. Nearly every great family had its abbé. The class did not survive the Revolution; but the courtesy title of abbé, having long lost all connection in people's minds with any special ecclesiastical function, remained as a convenient general term applicable to any clergyman. |
Abbot | Eastern Christian | Eastern Christian
In the Eastern Orthodox and Eastern Catholic Churches, the abbot is referred to as the hegumen. The Superior of a monastery of nuns is called the Hēguménē. The title of archimandrite (literally the head of the enclosure) used to mean something similar.
In the East, the principle set forth in the Corpus Juris Civilis still applies, whereby most abbots are immediately subject to the local bishop. Those monasteries which enjoy the status of being stauropegic will be subject only to a primate or his Synod of Bishops and not the local bishop. |
Abbot | Honorary and other uses of the title | Honorary and other uses of the title
Although currently in the Western Church the title "abbot" is given only abbots of monasteries, the title archimandrite is given to "monastics" (i.e., celibate) priests in the East, even when not attached to a monastery, as an honor for service, similar to the title of monsignor in the Latin Church of the Catholic Church. In the Eastern Orthodox Church, only monastics are permitted to be elevated to the rank of archimandrite. Married priests are elevated to the parallel rank of Archpriest or Protopresbyter. Normally there are no celibate priests who are not monastics in the Orthodox Church, with the exception of married priests who have been widowed. Since the time of Catherine II the ranks of Abbot and Archimandrite have been given as honorary titles in the Russian Church, and may be given to any monastic, even if he does not in fact serve as the superior of a monastery. In Greek practice the title or function of Abbot corresponds to a person who serves as the head of a monastery, although the title of the Archimandrite may be given to any celibate priest who could serve as the head of a monastery.
In the German Evangelical Church, the German title of Abt (abbot) is sometimes bestowed, like the French abbé, as an honorary distinction, and survives to designate the heads of some monasteries converted at the Reformation into collegiate foundations.
Of these the most noteworthy is Loccum Abbey in Hanover, founded as a Cistercian house in 1163 by Count Wilbrand of Hallermund, and reformed in 1593. The abbot of Loccum, who still carries a pastoral staff, takes precedence over all the clergy of Hanover, and was ex officio a member of the consistory of the kingdom. The governing body of the abbey consists of the abbot, prior and the "convent", or community, of Stiftsherren (canons).
In the Church of England, the Bishop of Norwich, by royal decree given by Henry VIII, also holds the honorary title of "Abbot of St. Benet." This title hails back to England's separation from the See of Rome, when King Henry, as supreme head of the newly independent church, took over all of the monasteries, mainly for their possessions, except for St. Benet, which he spared because the abbot and his monks possessed no wealth, and lived like simple beggars, deposing the incumbent Bishop of Norwich and seating the abbot in his place, thus the dual title still held to this day.
Additionally, at the enthronement of the Archbishop of Canterbury, there is a threefold enthronement, once in the throne the chancel as the diocesan bishop of Canterbury, once in the Chair of St. Augustine as the Primate of All England, and then once in the chapter-house as Titular Abbot of Canterbury.
There are several Benedictine abbeys throughout the Anglican Communion. Most of them have mitred abbots. |

During the years 1106–1107 AD, Daniel, a Russian Orthodox abbot, made a pilgrimage to the Holy Land and recorded his experiences. His diary was much-read throughout Russia, and at least seventy-five manuscript copies survive. Saint Joseph, Abbot of Volokolamsk, Russia (1439–1515), wrote a number of influential works against heresy, and about monastic and liturgical discipline, and Christian philanthropy.
In the Tales of Redwall series, the creatures of Redwall are led by an abbot or abbess. These "abbots" are appointed by the brothers and sisters of Redwall to serve as a superior and provide paternal care, much like real abbots.

Ardipithecus | Short description | Ardipithecus is a genus of an extinct hominine that lived during the Late Miocene and Early Pliocene epochs in the Afar Depression, Ethiopia. Originally described as one of the earliest ancestors of humans after they diverged from the chimpanzees, the relation of this genus to human ancestors and whether it is a hominin is now a matter of debate. Two fossil species are described in the literature: A. ramidus, which lived about 4.4 million years ago during the early Pliocene, and A. kadabba, dated to approximately 5.6 million years ago (late Miocene). Initial behavioral analysis indicated that Ardipithecus could be very similar to chimpanzees; however, more recent analysis based on canine size and lack of canine sexual dimorphism indicates that Ardipithecus was characterised by reduced aggression, and that they more closely resemble bonobos.
Some analyses describe Australopithecus as being sister to Ardipithecus ramidus specifically. This means that Australopithecus is distinctly more closely related to Ardipithecus ramidus than Ardipithecus kadabba. Cladistically, then, Australopithecus (and eventually Homo sapiens) indeed emerged within the Ardipithecus lineage, and this lineage is not literally extinct. |
Ardipithecus | ''Ardipithecus ramidus'' | Ardipithecus ramidus
A. ramidus was named in September 1994. The first fossil found was dated to 4.4 million years ago on the basis of its stratigraphic position between two volcanic strata: the basal Gaala Tuff Complex (G.A.T.C.) and the Daam Aatu Basaltic Tuff (D.A.B.T.). The name Ardipithecus ramidus stems mostly from the Afar language, in which Ardi means "ground/floor" and ramid means "root". The pithecus portion of the name is from the Greek word for "ape".
Like most hominids, but unlike all previously recognized hominins, it had a grasping hallux or big toe adapted for locomotion in the trees. It is not confirmed how many other features of its skeleton reflect adaptation to bipedalism on the ground as well. Like later hominins, Ardipithecus had reduced canine teeth and reduced canine sexual dimorphism.
In 1992–1993 a research team headed by Tim White discovered the first A. ramidus fossils—seventeen fragments including skull, mandible, teeth and arm bones—from the Afar Depression in the Middle Awash river valley of Ethiopia. More fragments were recovered in 1994, amounting to 45% of the total skeleton. This fossil was originally described as a species of Australopithecus, but White and his colleagues later published a note in the same journal renaming the fossil under a new genus, Ardipithecus. Between 1999 and 2003, a multidisciplinary team led by Sileshi Semaw discovered bones and teeth of nine A. ramidus individuals at As Duma in the Gona area of Ethiopia's Afar Region. The fossils were dated to between 4.35 and 4.45 million years old.
thumb|left|300px|Map showing discovery locations.
Ardipithecus ramidus had a small brain, measuring between 300 and 350 cm3. This is slightly smaller than a modern bonobo or female chimpanzee brain, but much smaller than the brain of australopithecines like Lucy (~400 to 550 cm3) and roughly 20% the size of the modern Homo sapiens brain. Like common chimpanzees, A. ramidus was much more prognathic than modern humans.
The teeth of A. ramidus lacked the specialization of other apes, and suggest that it was a generalized omnivore and frugivore (fruit eater) with a diet that did not depend heavily on foliage, fibrous plant material (roots, tubers, etc.), or hard and or abrasive food. The size of the upper canine tooth in A. ramidus males was not distinctly different from that of females. Their upper canines were less sharp than those of modern common chimpanzees in part because of this decreased upper canine size, as larger upper canines can be honed through wear against teeth in the lower mouth. The features of the upper canine in A. ramidus contrast with the sexual dimorphism observed in common chimpanzees, where males have significantly larger and sharper upper canine teeth than females. Of the living apes, bonobos have the smallest canine sexual dimorphism, although still greater than that displayed by A. ramidus.
The less pronounced nature of the upper canine teeth in A. ramidus has been used to infer aspects of the social behavior of the species and more ancestral hominids. In particular, it has been used to suggest that the last common ancestor of hominids and African apes was characterized by relatively little aggression between males and between groups. This is markedly different from social patterns in common chimpanzees, among which intermale and intergroup aggression are typically high. Researchers in a 2009 study said that this condition "compromises the living chimpanzee as a behavioral model for the ancestral hominid condition." Bonobo canine size and canine sexual dimorphism more closely resembles that of A. ramidus, and as a result, bonobos are now suggested as a behavioural model.
A. ramidus existed more recently than the most recent common ancestor of humans and chimpanzees (CLCA or Pan-Homo LCA) and thus is not fully representative of that common ancestor. Nevertheless, it is in some ways unlike chimpanzees, suggesting that the common ancestor differs from the modern chimpanzee. After the chimpanzee and human lineages diverged, both underwent substantial evolutionary change. Chimp feet are specialized for grasping trees; A. ramidus feet are better suited for walking. The canine teeth of A. ramidus are smaller, and equal in size between males and females, which suggests reduced male-to-male conflict, increased pair-bonding, and increased parental investment. "Thus, fundamental reproductive and social behavioral changes probably occurred in hominids long before they had enlarged brains and began to use stone tools," the research team concluded. |
Ardipithecus | Ardi | Ardi
On October 1, 2009, paleontologists formally announced the discovery of the relatively complete A. ramidus fossil skeleton first unearthed in 1994. The fossil is the remains of a small-brained female, nicknamed "Ardi", and includes most of the skull and teeth, as well as the pelvis, hands, and feet. It was discovered in Ethiopia's harsh Afar desert at a site called Aramis in the Middle Awash region. Radiometric dating of the layers of volcanic ash encasing the deposits suggest that Ardi lived about 4.3 to 4.5 million years ago. This date, however, has been questioned by others. Fleagle and Kappelman suggest that the region in which Ardi was found is difficult to date radiometrically, and they argue that Ardi should be dated at 3.9 million years.
The fossil is regarded by its describers as shedding light on a stage of human evolution about which little was known, more than a million years before Lucy (Australopithecus afarensis), the iconic early human ancestor candidate who lived 3.2 million years ago, and was discovered in 1974 just away from Ardi's discovery site. However, because the "Ardi" skeleton is no more than 200,000 years older than the earliest fossils of Australopithecus, and may in fact be younger than they are, some researchers doubt that it can represent a direct ancestor of Australopithecus.
Some researchers infer from the form of her pelvis and limbs and the presence of her abductable hallux, that "Ardi" was a facultative biped: bipedal when moving on the ground, but quadrupedal when moving about in tree branches. A. ramidus had a more primitive walking ability than later hominids, and could not walk or run for long distances. The teeth suggest omnivory, and are more generalised than those of modern apes. |
Ardipithecus | ''Ardipithecus kadabba'' | Ardipithecus kadabba
thumb|250px|Ardipithecus kadabba fossils
Ardipithecus kadabba is "known only from teeth and bits and pieces of skeletal bones", and is dated to approximately 5.6 million years ago. It has been described as a "probable chronospecies" (i.e. ancestor) of A. ramidus. Although originally considered a subspecies of A. ramidus, in 2004 anthropologists Yohannes Haile-Selassie, Gen Suwa, and Tim D. White published an article elevating A. kadabba to species level on the basis of newly discovered teeth from Ethiopia. These teeth show "primitive morphology and wear pattern" which demonstrate that A. kadabba is a distinct species from A. ramidus.
The specific name comes from the Afar word for "basal family ancestor". |
Ardipithecus | Classification | Classification
Due to several shared characteristics with chimpanzees, its closeness to ape divergence period, and due to its fossil incompleteness, the exact position of Ardipithecus in the fossil record is a subject of controversy. Primatologist Esteban Sarmiento had systematically compared and concluded that there is not sufficient anatomical evidence to support an exclusively human lineage. Sarmiento noted that Ardipithecus does not share any characteristics exclusive to humans, and some of its characteristics (those in the wrist and basicranium) suggest it diverged from humans prior to the human–gorilla last common ancestor. His comparative (narrow allometry) study in 2011 on the molar and body segment lengths (which included living primates of similar body size) noted that some dimensions including short upper limbs, and metacarpals are reminiscent of humans, but other dimensions such as long toes and relative molar surface area are great ape-like. Sarmiento concluded that such length measures can change back and forth during evolution and are not very good indicators of relatedness (homoplasy).
However, some later studies still argue for its classification in the human lineage. In 2014, it was reported that the hand bones of Ardipithecus, Australopithecus sediba and A. afarensis have the third metacarpal styloid process, which is absent in other apes. Unique brain organisations (such as lateral shift of the carotid foramina, mediolateral abbreviation of the lateral tympanic, and a shortened, trapezoidal basioccipital element) in Ardipithecus are also found only in the Australopithecus and Homo. Comparison of the tooth root morphology with those of the earlier Sahelanthropus also indicated strong resemblance, also pointing to inclusion to the human line.
Evolutionary tree according to a 2019 study: |
Ardipithecus | Paleobiology | Paleobiology
The Ardipithecus length measures are good indicators of function and together with dental isotope data and the fauna and flora from the fossil site indicate Ardipithecus was mainly a terrestrial quadruped collecting a large portion of its food on the ground. Its arboreal behaviors would have been limited and suspension from branches solely from the upper limbs rare. A comparative study in 2013 on carbon and oxygen stable isotopes within modern and fossil tooth enamel revealed that Ardipithecus fed both arboreally (on trees) and on the ground in a more open habitat, unlike chimpanzees.
In 2015, Australian anthropologists Gary Clark and Maciej Henneberg said that Ardipithecus adults have a facial anatomy more similar to chimpanzee subadults than adults, with a less-projecting face and smaller canines (large canines in primate males are used to compete within mating hierarchies), and attributed this to a decrease in craniofacial growth in favour of brain growth. This is only seen in humans, so they argued that the species may show the first trend towards human social, parenting and sexual psychology. Previously, it was assumed that such ancient human ancestors behaved much like chimps, but this is no longer considered to be a viable comparison. This view has yet to be corroborated by more detailed studies of the growth of A. ramidus. The study also provides support for Stephen Jay Gould's theory in Ontogeny and Phylogeny that the paedomorphic (childlike) form of early hominin craniofacial morphology results from dissociation of growth trajectories.
Clark and Henneberg also argued that such shortening of the skull—which may have caused a descension of the larynx—as well as lordosis—allowing better movement of the larynx—increased vocal ability, significantly pushing back the origin of language to well before the evolution of Homo. They argued that self domestication was aided by the development of vocalization, living in a pro-social society. They conceded that chimps and A. ramidus likely had the same vocal capabilities, but said that A. ramidus made use of more complex vocalizations, and vocalized at the same level as a human infant due to selective pressure to become more social. This would have allowed their society to become more complex. They also noted that the base of the skull stopped growing with the brain by the end of juvenility, whereas in chimps it continues growing with the rest of the body into adulthood; and considered this evidence of a switch from a gross skeletal anatomy trajectory to a neurological development trajectory due to selective pressure for sociability. Nonetheless, their conclusions are highly speculative.
According to Scott Simpson, the Gona Project's physical anthropologist, the fossil evidence from the Middle Awash indicates that both A. kadabba and A. ramidus lived in "a mosaic of woodland and grasslands with lakes, swamps and springs nearby," but further research is needed to determine which habitat Ardipithecus at Gona preferred. |

An assembly line, often called progressive assembly, is a manufacturing process where the unfinished product moves in a direct line from workstation to workstation, with parts added in sequence until the final product is completed. By mechanically moving parts to workstations and transferring the unfinished product from one workstation to another, a finished product can be assembled faster and with less labor than having workers carry parts to a stationary product.
Assembly lines are common methods of assembling complex items such as automobiles and other transportation equipment, household appliances and electronic goods.
Workers in charge of the works of assembly line are called assemblers. |
Assembly line | Concepts | Concepts
thumb|Lotus Cars assembly line as of 2008
Assembly lines are designed for the sequential organization of workers, tools or machines, and parts. The motion of workers is minimized to the extent possible. All parts or assemblies are handled either by conveyors or motorized vehicles such as forklifts, or gravity, with no manual trucking. Heavy lifting is done by machines such as overhead cranes or forklifts. Each worker typically performs one simple operation unless job rotation strategies are applied.
According to Henry Ford:
Designing assembly lines is a well-established mathematical challenge, referred to as an assembly line balancing problem. In the simple assembly line balancing problem the aim is to assign a set of tasks that need to be performed on the workpiece to a sequence of workstations. Each task requires a given task duration for completion. The assignment of tasks to stations is typically limited by two constraints: (1) a precedence graph which indicates what other tasks need to be completed before a particular task can be initiated (e.g. not putting in a screw before drilling the hole) and (2) a cycle time which restricts the sum of task processing times which can be completed at each workstation before the work-piece is moved to the next station by the conveyor belt. Major planning problems for operating assembly lines include supply chain integration, inventory control and production scheduling. |
Assembly line | Simple example | Simple example

Consider the assembly of a car: assume that certain steps in the assembly line are to install the engine, install the hood, and install the wheels (in that order, with arbitrary interstitial steps); only one of these steps can be done at a time. In traditional production, only one car would be assembled at a time. If engine installation takes 20 minutes, hood installation takes five minutes, and wheels installation takes 10 minutes, then a car can be produced every 35 minutes.
In an assembly line, car assembly is split between several stations, all working simultaneously. When a station is finished with a car, it passes it on to the next. By having three stations, three cars can be operated on at the same time, each at a different stage of assembly.
After finishing its work on the first car, the engine installation crew can begin working on the second car. While the engine installation crew works on the second car, the first car can be moved to the hood station and fitted with a hood, then to the wheels station and be fitted with wheels. After the engine has been installed on the second car, the second car moves to the hood assembly. At the same time, the third car moves to the engine assembly. When the third car's engine has been mounted, it then can be moved to the hood station; meanwhile, subsequent cars (if any) can be moved to the engine installation station.
Assuming no loss of time when moving a car from one station to another, the longest stage on the assembly line determines the throughput (20 minutes for the engine installation) so a car can be produced every 20 minutes, once the first car taking 35 minutes has been produced. |
Assembly line | History | History
Before the Industrial Revolution, most manufactured products were made individually by hand. A single craftsman or team of craftsmen would create each part of a product. They would use their skills and tools such as files and knives to create the individual parts. They would then assemble them into the final product, making cut-and-try changes in the parts until they fit and could work together (craft production).
Division of labor was practiced by Ancient Greeks, Chinese and other ancient civilizations. In Ancient Greece it was discussed by Plato and Xenophon. Adam Smith discussed the division of labour in the manufacture of pins at length in his book The Wealth of Nations (published in 1776).
The Venetian Arsenal, dating to about 1104, operated similar to a production line. Ships moved down a canal and were fitted by the various shops they passed. At the peak of its efficiency in the early 16th century, the Arsenal employed some 16,000 people who could apparently produce nearly one ship each day and could fit out, arm, and provision a newly built galley with standardized parts on an assembly-line basis. Although the Arsenal lasted until the early Industrial Revolution, production line methods did not become common even then. |
Assembly line | Industrial Revolution | Industrial Revolution
The Industrial Revolution led to a proliferation of manufacturing and invention. Many industries, notably textiles, firearms, clocks and watches,G.N. Georgano 1985. horse-drawn vehicles, railway locomotives, sewing machines, and bicycles, saw expeditious improvement in materials handling, machining, and assembly during the 19th century, although modern concepts such as industrial engineering and logistics had not yet been named.
thumb|right|The pulley block was the first manufactured product to become fully automated, at the Portsmouth Block Mills in the early 19th century.
The automatic flour mill built by Oliver Evans in 1785 was called the beginning of modern bulk material handling by Roe (1916). Evans's mill used a leather belt bucket elevator, screw conveyors, canvas belt conveyors, and other mechanical devices to completely automate the process of making flour. The innovation spread to other mills and breweries.
Probably the earliest industrial example of a linear and continuous assembly process is the Portsmouth Block Mills, built between 1801 and 1803. Marc Isambard Brunel (father of Isambard Kingdom Brunel), with the help of Henry Maudslay and others, designed 22 types of machine tools to make the parts for the rigging blocks used by the Royal Navy. This factory was so successful that it remained in use until the 1960s, with the workshop still visible at HM Dockyard in Portsmouth, and still containing some of the original machinery.Coad, Jonathan, The Portsmouth Block Mills : Bentham, Brunel and the start of the Royal Navy's Industrial Revolution, 2005, .
One of the earliest examples of an almost modern factory layout, designed for easy material handling, was the Bridgewater Foundry. The factory grounds were bordered by the Bridgewater Canal and the Liverpool and Manchester Railway. The buildings were arranged in a line with a railway for carrying the work going through the buildings. Cranes were used for lifting the heavy work, which sometimes weighed in the tens of tons. The work passed sequentially through to erection of framework and final assembly.

The first flow assembly line was initiated at the factory of Richard Garrett & Sons, Leiston Works in Leiston in the English county of Suffolk for the manufacture of portable steam engines. The assembly line area was called 'The Long Shop' on account of its length and was fully operational by early 1853. The boiler was brought up from the foundry and put at the start of the line, and as it progressed through the building it would stop at various stages where new parts would be added. From the upper level, where other parts were made, the lighter parts would be lowered over a balcony and then fixed onto the machine on the ground level. When the machine reached the end of the shop, it would be completed. |
Assembly line | Interchangeable parts | Interchangeable parts
During the early 19th century, the development of machine tools such as the screw-cutting lathe, metal planer, and milling machine, and of toolpath control via jigs and fixtures, provided the prerequisites for the modern assembly line by making interchangeable parts a practical reality.Beetz, Kirk H.

Steam-powered conveyor lifts began being used for loading and unloading ships some time in the last quarter of the 19th century. Hounshell (1984) shows a sketch of an electric-powered conveyor moving cans through a filling line in a canning factory.
The meatpacking industry of Chicago is believed to be one of the first industrial assembly lines (or disassembly lines) to be utilized in the United States starting in 1867. Workers would stand at fixed stations and a pulley system would bring the meat to each worker and they would complete one task. Henry Ford and others have written about the influence of this slaughterhouse practice on the later developments at Ford Motor Company. |

According to Domm, the implementation of mass production of an automobile via an assembly line may be credited to Ransom Olds, who used it to build the first mass-produced automobile, the Oldsmobile Curved Dash. Olds patented the assembly line concept, which he put to work in his Olds Motor Vehicle Company factory in 1901.
At Ford Motor Company, the assembly line was introduced by William "Pa" Klann upon his return from visiting Swift & Company's slaughterhouse in Chicago and viewing what was referred to as the "disassembly line", where carcasses were butchered as they moved along a conveyor. The efficiency of one person removing the same piece over and over without moving to another station caught his attention. He reported the idea to Peter E. Martin, soon to be head of Ford production, who was doubtful at the time but encouraged him to proceed. Others at Ford have claimed to have put the idea forth to Henry Ford, but Pa Klann's slaughterhouse revelation is well documented in the archives at the Henry Ford Museum and elsewhere, making him an important contributor to the modern automated assembly line concept. Ford was appreciative, having visited the highly automated 40-acre Sears mail order handling facility around 1906. At Ford, the process was an evolution by trial and error of a team consisting primarily of Peter E. Martin, the factory superintendent; Charles E. Sorensen, Martin's assistant; Clarence W. Avery; C. Harold Wills, draftsman and toolmaker; Charles Ebender; and József Galamb. Some of the groundwork for such development had recently been laid by the intelligent layout of machine tool placement that Walter Flanders had been doing at Ford up to 1908.
The moving assembly line was developed for the Ford Model T and began operation on October 7, 1913, at the Highland Park Ford Plant, and continued to evolve after that, using time and motion study. The assembly line, driven by conveyor belts, reduced production time for a Model T to just 93 minutes by dividing the process into 45 steps. Producing cars quicker than paint of the day could dry, it had an immense influence on the world.
In 1922, Ford (through his ghostwriter Crowther) said of his 1913 assembly line:
Charles E. Sorensen, in his 1956 memoir My Forty Years with Ford, presented a different version of development that was not so much about individual "inventors" as a gradual, logical development of industrial engineering:
As a result of these developments in method, Ford's cars came off the line in three-minute intervals or six feet per minute. This was much faster than previous methods, increasing production by eight to one (requiring 12.5 man-hours before, 1 hour 33 minutes after), while using less manpower. It was so successful, paint became a bottleneck. Only japan black would dry fast enough, forcing the company to drop the variety of colours available before 1914, until fast-drying Duco lacquer was developed in 1926.
The assembly line technique was an integral part of the diffusion of the automobile into American society. Decreased costs of production allowed the cost of the Model T to fall within the budget of the American middle class. In 1908, the price of a Model T was around $825, and by 1912 it had decreased to around $575. This price reduction is comparable to a reduction from $15,000 to $10,000 in dollar terms from the year 2000. In 1914, an assembly line worker could buy a Model T with four months' pay.
Ford's complex safety procedures—especially assigning each worker to a specific location instead of allowing them to roam about—dramatically reduced the rate of injury. The combination of high wages and high efficiency is called "Fordism", and was copied by most major industries. The efficiency gains from the assembly line also coincided with the take-off of the United States. The assembly line forced workers to work at a certain pace with very repetitive motions which led to more output per worker while other countries were using less productive methods.
In the automotive industry, its success was dominating, and quickly spread worldwide. Ford France and Ford Britain in 1911, Ford Denmark 1923, Ford Germany and Ford Japan 1925; in 1919, Vulcan (Southport, Lancashire) was the first native European manufacturer to adopt it. Soon, companies had to have assembly lines, or risk going broke by not being able to compete; by 1930, 250 companies which did not had disappeared.
The massive demand for military hardware in World War II prompted assembly-line techniques in shipbuilding and aircraft production. Thousands of Liberty ships were built making extensive use of prefabrication, enabling ship assembly to be completed in weeks or even days. After having produced fewer than 3,000 planes for the United States Military in 1939, American aircraft manufacturers built over 300,000 planes in World War II. Vultee pioneered the use of the powered assembly line for aircraft manufacturing. Other companies quickly followed. As William S. Knudsen (having worked at Ford, GM and the National Defense Advisory Commission) observed, "We won because we smothered the enemy in an avalanche of production, the like of which he had never seen, nor dreamed possible." |
Assembly line | Improved working conditions | Improved working conditions
In his 1922 autobiography, Henry Ford mentions several benefits of the assembly line including:
Workers do not do any heavy lifting.
No stooping or bending over.
No special training was required.
There are jobs that almost anyone can do.
Provided employment to immigrants.
The gains in productivity allowed Ford to increase worker pay from $1.50 per day to $5.00 per day once employees reached three years of service on the assembly line. Ford continued on to reduce the hourly work week while continuously lowering the Model T price. These goals appear altruistic; however, it has been argued that they were implemented by Ford in order to reduce high employee turnover: when the assembly line was introduced in 1913, it was discovered that "every time the company wanted to add 100 men to its factory personnel, it was necessary to hire 963" in order to counteract the natural distaste the assembly line seems to have inspired. |
Assembly line | Sociological problems | Sociological problems
Sociological work has explored the social alienation and boredom that many workers feel because of the repetition of doing the same specialized task all day long.
Karl Marx expressed in his theory of alienation the belief that, in order to achieve job satisfaction, workers need to see themselves in the objects they have created, that products should be "mirrors in which workers see their reflected essential nature". Marx viewed labour as a chance for people to externalize facets of their personalities. Marxists argue that performing repetitive, specialized tasks causes a feeling of disconnection between what a worker does all day, who they really are, and what they would ideally be able to contribute to society. Furthermore, Marx views these specialised jobs as insecure, since the worker is expendable as soon as costs rise and technology can replace more expensive human labour.Marx, Karl. "Comment on James Mill," Economic and Philosophical Manuscripts of 1844: 1844.
Since workers have to stand in the same place for hours and repeat the same motion hundreds of times per day, repetitive stress injuries are a possible pathology of occupational safety. Industrial noise also proved dangerous. When it was not too high, workers were often prohibited from talking. Charles Piaget, a skilled worker at the LIP factory, recalled that besides being prohibited from speaking, the semi-skilled workers had only 25 centimeters in which to move. Industrial ergonomics later tried to minimize physical trauma. |

Adelaide | Short description | Adelaide ( , ; ) is the capital and most populous city of South Australia, as well as the fifth-most populous city in Australia. The name "Adelaide" may refer to either Greater Adelaide (including the Adelaide Hills) or the Adelaide city centre. The demonym Adelaidean is used to denote the city and the residents of Adelaide. The traditional owners of the Adelaide region are the Kaurna.SCD2018/001 – Kaurna Peoples Native Title Claim National Native Title Tribunal. Retrieved 1 October 2022.Kaurna Heritage City of Adelaide. Retrieved 1 October 2022. The name in their language refers to the area of the city centre and surrounding Park Lands. Adelaide is situated on the Adelaide Plains north of the Fleurieu Peninsula, between the Gulf St Vincent in the west and the Mount Lofty Ranges in the east. Its metropolitan area extends from the coast to the foothills of the Mount Lofty Ranges, and stretches from Gawler in the north to Sellicks Beach in the south.
Named in honour of Adelaide of Saxe-Meiningen, wife of King William IV, the city was founded in 1836 as the planned capital for the only freely settled British province in Australia, distinguishing it from Australia's penal colonies. Colonel William Light, one of Adelaide's founding fathers, designed the city centre and chose its location close to the River Torrens. Light's design, now listed as national heritage, set out the city centre in a grid layout known as "Light's Vision", interspaced by wide boulevards and large public squares, and entirely surrounded by park lands. Colonial Adelaide was noted for its leading examples of religious freedom and progressive political reforms and became known as the "City of Churches" due to its diversity of faiths. It was Australia's third-most populous city until the postwar era.
Today, Adelaide is one of Australia's most visited travel destinations and hosts many festivals and sporting events, such as the Adelaide 500, Tour Down Under, LIV Golf Adelaide, and the Adelaide Fringe, the world's second largest annual arts festival, contributing to its rising tourism sector. The city has also been renowned for its automotive industry, having been the original host of the Australian Grand Prix in the FIA Formula One World Championship from 1985 to 1995. Other features include its food and wine industries, its coastline and hills, its large defence and manufacturing operations, and its emerging space sector, including the Australian Space Agency being headquartered there. Adelaide routinely ranks among the world's most liveable cities, at one stage being named the most liveable city in the country, third in the world. Its aesthetic appeal has also been recognised by Architectural Digest, which ranked Adelaide as the most beautiful city in the world in 2024.
As South Australia's government and commercial centre, Adelaide is the site of many governmental and financial institutions. Most of these are concentrated in the central business district along the cultural boulevards of North Terrace and King William Street. Adelaide has also been classed as a Gamma + level global city as categorised by the Globalization and World Cities Research Network, with the city further linking economic regions to the worldwide economy. Adelaide is connected by extensive bus, train and tram networks, all of which are operated by Adelaide Metro with its main railway terminus at the Adelaide railway station. The city is also served by Adelaide Airport, the nation's fifth largest airport, for air travel. Additionally, Port Adelaide serves as Adelaide's hub for sea travel, as well as its main seaport. |

The area around modern-day Adelaide was originally inhabited by the Kaurna people, one of many Aboriginal tribes in South Australia. The city and parklands area also known as Tarntanya, Tandanya (now the short name of Tandanya National Aboriginal Cultural Institute), Tarndanya, or Tarndanyangga (now the dual name for Victoria Square in the Kaurna language). The name means 'male red kangaroo rock', referring to a rock formation on the site that has now been destroyed.
The surrounding area was an open, grassy plain with patches of trees and shrubs, which had been managed by hundreds of generations. Kaurna country encompassed the plains stretching north and south of Tarntanya, as well as the wooded foothills of the Mt Lofty Ranges. The River Torrens was known as the Karrawirra Pari (Red Gum forest river). About 300 Kaurna populated the Adelaide area, and were referred to by the settlers as the Cowandilla.
The more than 20 local clans across the plain lived seminomadic lives, with extensive mound settlements where huts were built repeatedly over centuries and a complex social structure, including a class of sorcerers separated from regular society.
Within a few decades of European settlement of South Australia, Kaurna culture was almost completely lost. The last speaker of Kaurna language died in 1929. Extensive documentation by early missionaries and other researchers has enabled a modern revival of both, which has included a commitment by local and state governments to rename or include Kaurna names for many local places. |

Based on the ideas of Edward Gibbon Wakefield about colonial reform, Robert Gouger petitioned the British government to create a new colony in Australia, resulting in the passage of the South Australia Act 1834. Physical establishment of the colony began with the arrival of the first British colonisers in February 1836. The first governor
proclaimed the commencement of colonial government in South Australia on 28 December 1836, near The Old Gum Tree in what is now the suburb of Glenelg North. The event is commemorated in South Australia as Proclamation Day. The site of the colony's capital was surveyed and laid out by Colonel William Light, the first surveyor-general of South Australia, with his own original, unique, topographically sensitive design. The city was named after Queen Adelaide.
Adelaide was established as a planned colony of free immigrants, promising civil liberties and freedom from religious persecution, based upon the ideas of Edward Gibbon Wakefield. Wakefield had read accounts of Australian settlement while in prison in London for attempting to abduct an heiress,Wakefield cites:
Edward Curr, An Account of the Colony of Van Diemen's Land, principally designed for the use of emigrants, George Cowie & Co., London, 1824;
Henry Widdowson, Present State of Van Diemen's Land; comprising an account of its agricultural capabilities, with observations on the present state of farming, &c. &c. pursued in that colony: and other important matters connected with Emigration, S. Robinson, W. Joy and J. Cross, London, and J. Birdsall, Northampton, 1829; and

Cross, London, 1826 and realised that the eastern colonies suffered from a lack of available labour, due to the practice of giving land grants to all arrivals.Wakefield, Letter from Sydney, December 1829, pp. 99–185, written from Newgate prison. Editor Robert Gouger. Wakefield's idea was for the Government to survey and sell the land at a rate that would maintain land values high enough to be unaffordable for labourers and journeymen.Wakefield wrote about this under a pseudonym, purporting to be an Australian settler. His subterfuge was so successful that he confused later writers, including Karl Marx, who wrote "It is the great merit of E.G. Wakefield to have discovered not anything new about the Colonies, but to have discovered in the Colonies the truth of as to the condition of capitalist production in the mother-country.' Das Kapital, Moscow, 1958, p 766" Funds raised from the sale of land were to be used to bring out working-class emigrants, who would have to work hard for the monied settlers to ever afford their own land.Plan of a Company to be Established for the Purpose of Founding a Colony in Southern Australia, Purchasing Land Therein, and Preparing the Land so Purchased for the Reception of Immigrants, 1832; in Wakefield, Edward Gibbon, Prichard, M. F., (ed.) The Collected Works of Edward Gibbon Wakefield, Collins, London, 1968, p 290. As a result of this policy, Adelaide does not share the convict settlement history of other Australian cities like Sydney, Brisbane and Hobart.

As it was believed that in a colony of free settlers there would be little crime, no provision was made for a gaol in Colonel Light's 1837 plan. But by mid-1837 the South Australian Register was warning of escaped convicts from New South Wales and tenders for a temporary gaol were sought. Following a burglary, a murder, and two attempted murders in Adelaide during March 1838, Governor Hindmarsh created the South Australian Police Force (now the South Australia Police) in April 1838 under 21-year-old Henry Inman.J. W. Bull; Early Experiences of Colonial Life in South Australia (Adelaide, 1878) p.67 The first sheriff, Samuel Smart, was wounded during a robbery, and on 2 May 1838 one of the offenders, Michael Magee, became the first person to be hanged in South Australia. William Baker Ashton was appointed governor of the temporary gaol in 1839, and in 1840 George Strickland Kingston was commissioned to design Adelaide's new gaol. Construction of Adelaide Gaol commenced in 1841.
Adelaide's early history was marked by economic uncertainty and questionable leadership. The first governor of South Australia, John Hindmarsh, clashed frequently with others, in particular the Resident Commissioner, James Hurtle Fisher. The rural area surrounding Adelaide was surveyed by Light in preparation to sell a total of over of land. Adelaide's early economy started to get on its feet in 1838 with the arrival of livestock from Victoria, New South Wales and Tasmania. Wool production provided an early basis for the South Australian economy. By 1860, wheat farms had been established from Encounter Bay in the south to Clare in the north.
thumb|left|upright|alt= Refer to caption|1888 map of Adelaide, showing the gradual development of its urban layout
George Gawler took over from Hindmarsh in late 1838 and, despite being under orders from the Select Committee on South Australia in Britain not to undertake any public works, promptly oversaw construction of a governor's house, the Adelaide Gaol, police barracks, a hospital, a customs house and a wharf at Port Adelaide. Gawler was recalled and replaced by George Edward Grey in 1841. Grey slashed public expenditure against heavy opposition, although its impact was negligible at this point: silver was discovered in Glen Osmond that year, agriculture was well underway, and other mines sprung up all over the state, aiding Adelaide's commercial development. The city exported meat, wool, wine, fruit and wheat by the time Grey left in 1845, contrasting with a low point in 1842 when one-third of Adelaide houses were abandoned.
Trade links with the rest of the Australian states were established after the Murray River was successfully navigated in 1853 by Francis Cadell, an Adelaide resident. South Australia became a self-governing colony in 1856 with the ratification of a new constitution by the British parliament. Secret ballots were introduced, and a bicameral parliament was elected on 9 March 1857, by which time 109,917 people lived in the province.
In 1860, the Thorndon Park reservoir was opened, providing an alternative water source to the now turbid River Torrens. Gas street lighting was implemented in 1867, the University of Adelaide was founded in 1874, the South Australian Art Gallery opened in 1881 and the Happy Valley Reservoir opened in 1896. In the 1890s Australia was affected by a severe economic depression, ending a hectic era of land booms and tumultuous expansionism. Financial institutions in Melbourne and banks in Sydney closed. The national fertility rate fell and immigration was reduced to a trickle.
The value of South Australia's exports nearly halved. Drought and poor harvests from 1884 compounded the problems, with some families leaving for Western Australia. Adelaide was not as badly hit as the larger gold-rush cities of Sydney and Melbourne, and silver and lead discoveries at Broken Hill provided some relief. Only one year of deficit was recorded, but the price paid was retrenchments and lean public spending. Wine and copper were the only industries not to suffer a downturn. |

Adelaide was Australia's third largest city for most of the 20th century. Electric street lighting was introduced in 1900 and electric trams were transporting passengers in 1909. 28,000 men were sent to fight in World War I. Historian F. K. Crowley examined the reports of visitors in the early 20th century, noting that "many visitors to Adelaide admired the foresighted planning of its founders", as well as pondering the riches of the young city.F.K. Crowle y(1973). Modern Australia in Documents: 1901–1939. Wren.
Adelaide enjoyed a postwar boom, entering a time of relative prosperity. Its population grew, and it became the third most populous metropolitan area in the country, after Sydney and Melbourne. Its prosperity was short-lived, with the return of droughts and the Great Depression of the 1930s. It later returned to fortune under strong government leadership. Secondary industries helped reduce the state's dependence on primary industries. World War II brought industrial stimulus and diversification to Adelaide under the Playford Government, which advocated Adelaide as a safe place for manufacturing due to its less vulnerable location.Cockburn, S (1991): Playford – Benevolent Despot. Axiom Publishing. P. 85. Shipbuilding was expanded at the nearby port of Whyalla.
The South Australian Government in this period built on former wartime manufacturing industries but neglected cultural facilities which meant South Australia's economy lagged behind. International manufacturers like Holden and ChryslerWhen Chrysler stopped manufacturing in Adelaide, Mitsubishi Motors Australia took over the Tonsley Park factory. After many years of mixed fortunes, Mitsubishi ceased manufacturing at Tonsley Park on 27 March 2008. made use of these factories around the Adelaide area in suburbs like Elizabeth, completing its transformation from an agricultural service centre to a 20th-century motor city. The Mannum–Adelaide pipeline brought River Murray water to Adelaide in 1955 and an airport opened at West Beach in 1955. Flinders University and the Flinders Medical Centre were established in the 1960s at Bedford Park, south of the city. Today, Flinders Medical Centre is one of the largest teaching hospitals in South Australia. In the post-war years around the early 1960s, Adelaide was surpassed by Brisbane as Australia's third largest city.
The Dunstan Governments of the 1970s saw something of an Adelaide "cultural revival", establishing a wide array of social reforms. The city became noted for its progressivism as South Australia became the first Australian state or territory to decriminalise homosexuality between consenting adults in 1975. Adelaide became a centre for the arts, building upon the biennial "Adelaide Festival of Arts" that commenced in 1960. The State Bank collapsed in 1991 during an economic recession. The effects lasted until 2004, when Standard & Poor's reinstated South Australia's AAA credit rating. Adelaide's tallest building, completed in 2020, is called the Adelaidean and is located at 11 Frome Street. |

In the early years of the 21st century, a significant increase in the state government's spending on Adelaide's infrastructure occurred. The Rann government invested A$535 million in a major upgrade of the Adelaide Oval to enable Australian Football League to be played in the city centreMichael Owen, The Australian, 3 December 2009 and more than A$2 billion to build a new Royal Adelaide Hospital on land adjacent to the Adelaide Railway Station.ABC News, Wednesday 7 June 2006 The Glenelg tramline was extended through the city to HindmarshABC News, 6 April 2005 down to East Terrace and the suburban railway line extended south to Seaford.ABC News, 13 May 2009
Following a period of stagnation in the 1990s and 2000s, Adelaide began several major developments and redevelopments. The Adelaide Convention Centre was redeveloped and expanded at a cost of A$350 million beginning in 2012.ABC News, 29 June 2011 Three historic buildings were adapted for modern use: the Torrens Building in Victoria Square as the Adelaide campus for Carnegie Mellon University, University College London, and Torrens University;News Release Government of SA, 15 May 2005 the Stock Exchange building as the Science Exchange of the Royal Institution Australia; and the Glenside Psychiatric Hospital as the Adelaide Studios of the SA Film Corporation.

Much of Adelaide was bushland before British settlement, with some variation – sandhills, swamps and marshlands were prevalent around the coast. The loss of the sandhills to urban development had a particularly destructive effect on the coastline due to erosion.The Adelaide Metropolitan Coastline Coastline, South Australian Coastal Protection Board, No. 27, April 1993. Retrieved 6 December 2015. Where practical, the government has implemented programs to rebuild and vegetate sandhills at several of Adelaide's beachside suburbs. Tennyson Dunes is the largest contiguous, tertiary dune system contained entirely within Metropolitan Adelaide, providing refuge for a variety of remnant species formerly found along the entire coastline. Much of the original vegetation has been cleared with what is left to be found in reserves such as the Cleland National Park and Belair National Park. A number of creeks and rivers flow through the Adelaide region. The largest are the Torrens and Onkaparinga catchments. Adelaide relies on its many reservoirs for water supply with the Happy Valley Reservoir supplying around 40% and the much larger Mount Bold Reservoir 10% of Adelaide's domestic requirements respectively. |

The uplands of the Adelaide Hills, part of the southern Mount Lofty Ranges to the east of Adelaide, are defined on their western side by a number of arcuate faults (the Para, Eden, Clarendon and Willunga Faults), and consist of rocks such as siltstone, dolomite and quartzite, dating from the Neoproterozoic to the middle Cambrian, laid down in the Adelaide Rift Complex, the oldest part of the Adelaide Superbasin.
Most of the Adelaide metropolitan area lies in the downthrown St Vincent Basin and its embayments, including the Adelaide Plains Sub-basin, and the Golden Grove, Noarlunga and Willunga Embayments. These basins contain deposits of Tertiary marine and non-marine sands and limestones, which form important aquifers.Lindsay J.M. & Alley, N.F. (1995): St Vincent Basin.

Adelaide | Urban layout | Urban layout
Adelaide is a planned city, designed by the first Surveyor-General of South Australia, Colonel William Light. His plan, sometimes referred to as "Light's Vision" (also the name of a statue of him on Montefiore Hill), arranged Adelaide in a grid, with five squares in the Adelaide city centre and a ring of parks, known as the Adelaide Parklands, surrounding it. Light's selection of the location for the city was initially unpopular with the early settlers, as well as South Australia's first governor, John Hindmarsh, due to its distance from the harbour at Port Adelaide, and the lack of fresh water there.Page, M. (1981): Port Adelaide and its Institute, 1851–1979. Rigby Publishers Ltd. Pp.17–20.
thumb|The city centre was built on a grid plan, known as Light's Vision.
Light successfully persisted with his choice of location against this initial opposition. Recent evidence suggests that Light worked closely with George Kingston as well as a team of men to set out Adelaide, using various templates for city plans going back to Ancient Greece, including Italian Renaissance designs and the similar layouts of the American cities Philadelphia and Savannah–which, like Adelaide, follow the same layout of a central city square, four complementing city squares surrounding it and a parklands area that surrounds the city centre.
thumb|Aerial view of Victoria Square, one of the five main squares in the city centre and considered the heart of Adelaide's grid layout
The benefits of Light's design are numerous: Adelaide has had wide multi-lane roads from its beginning, an easily navigable cardinal direction grid layout and an expansive green ring around the city centre. There are two sets of ring roads in Adelaide that have resulted from the original design. The inner ring route (A21) borders the parklands, and the outer route (A3/A13/A16/A17) completely bypasses the inner city via (in clockwise order) Grand Junction Road, Hampstead Road, Ascot Avenue, Portrush Road, Cross Road and South Road.Adelaide's Inner and Outer Ring Routes , 24 August 2004, South Australian Department of Transport.
Suburban expansion has to some extent outgrown Light's original plan. Numerous former outlying villages and "country towns", as well as the satellite city of Elizabeth, have been enveloped by its suburban sprawl. Expanding developments in the Adelaide Hills region led to the construction of the South Eastern Freeway to cope with growth, which has subsequently led to new developments and further improvements to that transport corridor. Similarly, the booming development in Adelaide's South led to the construction of the Southern Expressway.
New roads are not the only transport infrastructure developed to cope with the urban growth. The O-Bahn Busway is an example of a unique solution to Tea Tree Gully's transport woes in the 1980s. The development of the nearby suburb of Golden Grove in the late 1980s followed a planned approach to urban growth.
In the 1960s, a Metropolitan Adelaide Transport Study Plan was proposed to cater for the future growth of the city. The plan involved the construction of freeways, expressways and the upgrade of certain aspects of the public transport system. The then premier Steele Hall approved many parts of the plan and the government went as far as purchasing land for the project. The later Labor government elected under Don Dunstan shelved the plan, but allowed the purchased land to remain vacant, should the future need for freeways arise. In 1980, the Liberal party won government and premier David Tonkin committed his government to selling off the land acquired for the MATS plan, ensuring that even when needs changed, the construction of most MATS-proposed freeways would be impractical. Some parts of this land have been used for transport, (e.g. the O-Bahn Busway and Southern Expressway), while most has been progressively subdivided for residential use.
In 2008, the SA Government announced plans for a network of transport-oriented developments across the Adelaide metropolitan area and purchased a 10 hectare industrial site at Bowden for $52.5 million as the first of these developments."Clipsal site at Bowden to become a green village", Ministerial Press Release, 24 October 2008, SA Govt.

Adelaide | Housing | Housing
thumb|right|Terraced housing on North Terrace
Historically, Adelaide's suburban residential areas have been characterised by single-storey detached houses built on blocks. A relative lack of suitable, locally-available timber for construction purposes led to the early development of a brick-making industry, as well as the use of stone, for houses and other buildings. By 1891, 68% of houses were built of stone, 15% of timber, and 10% of brick, with brick also being widely used in stone houses for quoins, door and window surrounds, and chimneys and fireplaces.Gibbs, R.M. (2013): Under the burning sun: a history of colonial South Australia, 1836–1900. Peacock Publications. Pp. 58, 333–4.
There is a wide variety in the styles of these houses. Until the 1960s, most of the more substantial houses were built of red brick, though many front walls were of ornamental stone. Then cream bricks became fashionable, and in the 1970s, deep red and brown bricks became popular. Until the 1970s, roofs tended to be clad with (painted) corrugated iron or cement or clay tiles, usually red "terracotta". Since then, Colorbond corrugated steel has dominated. Most roofs are pitched. Flat roofs are not common.
Up to the 1970s, most houses were of "double brick" construction on concrete footings, with timber floors laid on joists supported by "dwarf walls". Later houses have mainly been of "brick veneer" construction – structural timber or, more recently, lightweight steel frame on a concrete slab foundation, lined with Gyprock, and with an outer skin of brickwork,Rosemary Cadden: Building South Australia: celebrating 125 years. Solstice Media. pp. 77, 87. to cope with Adelaide's reactive soils, particularly Keswick Clay, black earth and some red-brown earth soils.Sheard, M. J., & A. P. Belperio (1995): "Problem soils". In: Drexel, J. F. & Preiss, W. V. (eds.) The geology of South Australia. Vol.2, The Phanerozoic. p. 274. South Australia Geological Survey, Bulletin 54. The use of precast concrete panels for floor and wall construction has also increased. In addition to this, a significant factor in Adelaide's suburban history is the role of the South Australian Housing Trust. |

There are two systems of primary and secondary schools, a public system operated by the South Australian Government's Department for Education, and a private system of independent and Catholic schools. South Australian schools provide education under the Australian Curriculum for reception to Year 10 students. In Years 10 to 12, students study for the South Australian Certificate of Education (SACE). They have the option of incorporating vocational education and training (VET) courses or a flexible learning option (FLO). South Australia also has 24 schools that use International Baccalaureate programs as an alternative to the Australian Curriculum or SACE. These programs include the IB Primary Years Programme, the IB Middle Years Programme, and the IB Diploma Programme.
For South Australian students who cannot attend a traditional school, including students who live in rural or remote areas, the state government runs the Open Access College (OAC), which provides virtual teaching. The OAC has a campus in Marden which caters to students from reception to Year 12 and adults who haven't been able to complete their SACE.

The University of South Australia, with 37,000 students, has two North Terrace campuses, three other campuses in the metropolitan area and campuses in the regional cities of Whyalla and Mount Gambier. The University of Adelaide and the University of South Australia have had multiple proposals to merge into a single university. A proposal in 2018 failed due to uncertainty as to the new name and leadership of the merged university. In 2022, the universities announced a new merger proposal, with the name and leadership issues settled and support from the South Australian government.

While established as a British province, and very much English in terms of its culture, Adelaide attracted immigrants from other parts of Europe early on, including German and other European non-conformists escaping religious persecution. The first German Lutherans arrived in 1838,Monteath, P., Paul, M., & Martin, R. (2014): Interned: Torrens Island 1914–1915, Wakefield Press, p. 8 bringing with them the vine cuttings that they used to found the acclaimed wineries of the Barossa Valley.
The Royal Adelaide Show is an annual agricultural show and state fair, established in 1839 and now a huge event held in the Adelaide Showground annually.
Adelaide's arts scene flourished in the 1960s and 1970s with the support of successive premiers from both major political parties. The renowned Adelaide Festival of Arts was established in 1960 under Thomas Playford, which in the same year spawned an unofficial uncurated series of performances and exhibits which grew into the Adelaide Fringe. Construction of the Adelaide Festival Centre began under Steele Hall in 1970 and was completed under the subsequent government of Don Dunstan, who also established the South Australian Film Corporation in 1972 and the State Opera of South Australia in 1976.
Over time, the Adelaide Festival expanded to include Adelaide Writers' Week and WOMADelaide, and other separate festivals were established, such as the Adelaide Cabaret Festival (2002), the Adelaide Festival of Ideas (1999), the Adelaide Film Festival (2013), FEAST (1999, a queer culture), Tasting Australia (1997, a food and wine affair), and Illuminate Adelaide (2021). With the Festival, the Fringe, WOMADelaide, Writers' Week and the Adelaide 500 street motor racing event (along with evening music concerts) all happening in early March, the period became known colloquially as "Mad March".
In 2014, Ghil'ad Zuckermann founded the Adelaide Language Festival.
There are many international cultural fairs, most notably the German Schützenfest and Greek Glendi. Adelaide holds an annual Christmas pageant, the world's largest Christmas parade.

As the state capital, Adelaide has a great number of cultural institutions, many of them along the boulevard of North Terrace. The Art Gallery of South Australia, with about 35,000 works, holds Australia's second largest state-based collection. Adjacent are the South Australian Museum and State Library of South Australia. The Adelaide Botanic Garden, National Wine Centre and Tandanya National Aboriginal Cultural Institute are nearby in the East End of the city. In the back of the State Library lies the Migration Museum, Australia's oldest museum of its kind.
Further west, the Lion Arts Centre is home to ACE Open, which showcases contemporary art; Dance Hub SA; and other studios and arts industry spaces. The Mercury Cinema and the JamFactory ceramics and design gallery are just around the corner. |

The Adelaide Festival Centre (which includes the Dunstan Playhouse, Festival Theatre and Space Theatre), on the banks of the Torrens, is the focal point for much of the cultural activity in the city and home to the State Theatre Company of South Australia. Other live music and theatre venues include the Adelaide Entertainment Centre; Adelaide Oval; Memorial Drive Park; Thebarton Theatre; Adelaide Town Hall; Her Majesty's Theatre; Queen's Theatre; Holden Street Theatres; and the Hopgood Theatre.
The Lion Arts Factory, within the Lion Arts Centre, hosts contemporary music in a wide range of genres, as does "The Gov" in Hindmarsh. The city also has numerous smaller theatres, pubs and cabaret bars which host performances. |
Adelaide | Music | Music
thumb|The Thebarton Theatre, colloquially known as the "Thebby", is one of South Australia's most popular live music venues.
In 2015, it was said that there were now more live music venues per capita in Adelaide than any other capital city in the southern hemisphere, Lonely Planet labelled Adelaide "Australia's live music city", and the city was recognised as a "City of Music" by the UNESCO Creative Cities Network. Although there were many pubs hosting live music in the CBD in past, the number has slowly diminished. The Grace Emily on Waymouth Street, which was refurbished as a live music venue around 2000, is popular with musicians and patrons alike. The Crown & Anchor ("the Cranker") was saved from demolition in 2024 after a vigorous campaign by the public as well as many musicians and politicians. New legislation passed on 11 September 2024 designates the entire Adelaide CBD as a "live music venue area", and gives protection to selected live music venues.
In addition to its own WOMAD (WOMADelaide), Adelaide has attracted several touring music festivals, including Creamfields, Laneway, and Groovin' (some since defunct).
Adelaide has produced musical groups and individuals who have achieved national and international fame. These include the Adelaide Symphony Orchestra, the Adelaide Youth Orchestra, rock bands The Angels, Atlas Genius, Cold Chisel, The Superjesus, Wolf & Cub, roots/blues group The Audreys, internationally acclaimed metal acts I Killed The Prom Queen and Double Dragon, popular Australian hip-hop outfit Hilltop Hoods, as well as pop acts like Sia, Orianthi, Guy Sebastian, and Wes Carr, and the internationally successful tribute act, The Australian Pink Floyd Show.
Noted rocker Jimmy Barnes (formerly lead vocalist with Cold Chisel) spent most of his youth in the northern suburb of Elizabeth. Australian singer-songwriter Paul Kelly grew up in Adelaide and was head prefect at Rostrevor College. The first Australian Idol winner, Guy Sebastian, hails from the north-eastern suburb of Golden Grove. |

All of the five Australian national television networks broadcast both high-definition digital and standard-definition digital television services in Adelaide. They share three transmission towers on the ridge near the summit of Mount Lofty. There are two other transmission sites at 25 Grenfell Street, Adelaide and Elizabeth Downs. The two government-funded stations are run by the Australian Broadcasting Corporation (ABC South Australia) and the Special Broadcasting Service (SBS). The Seven Network and Network Ten both own their Adelaide stations (SAS-7 and ADS-10 respectively). Adelaide's NWS-9 is part of the Nine Network. Adelaide also has a community television station, Channel 44.
As part of a nationwide phase-out of analogue television in Australia, Adelaide's analogue television service was shut down on 2 April 2013.
The Foxtel pay TV service is also available via cable or satellite to the entire metropolitan area.
All the major broadcasting networks also operate online on-demand television services, alongside internet-only services such as Stan, Fetch TV, Netflix, YouTube, Disney+, and Kayo Sports. |

The main sports played professionally in Adelaide are Australian Rules football, soccer, cricket, netball, and basketball. Adelaide is the home of two Australian Football League teams: the Adelaide Football Club and Port Adelaide Football Club, and one A-League soccer team, Adelaide United. A local Australian rules football league, the South Australian National Football League (SANFL), is made up of 10 teams from around Adelaide. The SANFL has been in operation since 1877 when it began as the South Australian Football Association (SAFA) before changing its name to the SANFL in 1927. The SANFL is the oldest surviving football league of any code played in Australia.
Adelaide has developed a strong culture of attracting crowds to major sporting events. Until the completion of the 2012–14 renovation and upgrade of the Adelaide Oval, most large sporting events took place at either Football Park (the then home base of the Adelaide Crows, and the then Port Adelaide home game venue), or the historic Adelaide Oval, home of the South Australia Redbacks and the Adelaide Strikers cricket teams. Since completion of the upgrade, home games for Adelaide Crows and Port Adelaide now take place at Adelaide Oval.
Since 1884, Adelaide Oval has also hosted an international cricket test every summer, along with a number of One Day International cricket matches. Memorial Drive Park, adjacent to the Adelaide Oval, used to host Davis Cup and other major tennis events, including the Australian Open and the Adelaide International. Adelaide's professional association football team, Adelaide United, play in the A-League. Founded in 2003, their home ground is Coopers Stadium, which has a capacity of 16,500 and is one of the few purpose-built soccer stadia in Australia. Prior to United's foundation, Adelaide City and West Adelaide represented the city in the National Soccer League. The two sides, which contest the Adelaide derby against one another, now play in the National Premier Leagues South Australia.
For two years, 1997 and 1998, Adelaide was represented in Australia's top level rugby league, after the New South Wales Rugby League had played a single game per season at the Adelaide Oval for five years starting in 1991. The Adelaide Rams were formed and played in the breakaway Super League (SL) competition in 1997 before moving to the new National Rugby League in 1998. Initially playing at the Adelaide Oval, the club moved to the more suitable Hindmarsh Stadium late in the 1998 season. As part of a peace deal with the Australian Rugby League to end the Super League war, the club's owners News Limited (who were also owners of the SL) suddenly closed the club only weeks before the start of the 1999 season.
Adelaide has two professional basketball teams, the men's team being the Adelaide 36ers which plays in the National Basketball League (NBL) and the women's team, the Adelaide Lightning which plays in the Women's National Basketball League (WNBL). The Adelaide 36ers play at the Adelaide Entertainment Centre while the Adelaide Lightning play at the Adelaide Arena (Previously Titanium Security Arena). Adelaide has a professional netball team, the Adelaide Thunderbirds, which plays in the national netball competition, the Suncorp Super Netball championship, with home games played at Netball SA Stadium. The Thunderbirds occasionally play games or finals at the Titanium Security Arena, while international netball matches are usually played at the 10,500 seat Adelaide Entertainment Centre. The Titanium Security Arena has a capacity of 8,000 and is the largest purpose-built basketball stadium in Australia.
thumb|The Tour Down Under is the first event of the UCI World Tour calendar.
Since 1999 Adelaide and its surrounding areas have hosted the Tour Down Under bicycle race, organised and directed by Adelaide-based Michael Turtur. Turtur won an Olympic gold medal for Australia in the 4000 m team pursuit at the 1984 Los Angeles Olympics. The Tour Down Under is the largest cycling event outside Europe and was the first event outside Europe to be granted UCI ProTour status.
The 2024 Women's Tour Down Under cycle stage race was held in and around Adelaide, South Australia from 12 to 14 January 2024
Adelaide maintains a franchise in the Australian Baseball League, the Adelaide Giants. They have been playing since 2009, and their home stadium (until 2016) was Norwood Oval. From 2016 the team moved to the Diamond Sports Stadium located near the Adelaide International Airport due to renovations at Norwood.
Adelaide also has an ice hockey team, Adelaide Adrenaline in the Australian Ice Hockey League (AIHL). It was national champions in 2009 and plays its games at the IceArenA.

The Australian Grand Prix for World Championship Formula One racing was hosted by Adelaide from 1985 to 1995 on the Adelaide Street Circuit which was laid out in the city's East End as well as the eastern parklands including the Victoria Park Racecourse. The Grand Prix became a source of pride, and losing the event to Melbourne in a surprise announcement in mid-1993 left a void that has since been filled with the Adelaide 500 for V8 Supercar racing, held on a modified version of the same street circuit. The Classic Adelaide, a rally of classic sporting vehicles, is also held in the city and its surrounds.
Adelaide formerly had three horse racing venues. Victoria Park, Cheltenham Park Racecourse, both of which have now closed, and Morphettville Racecourse that remains the home of the South Australian Jockey Club. It also has Globe Derby Park for Harness racing that opened in 1969, and by 1973 had become Adelaide's premier harness racing venue taking over from the Wayville Showgrounds, as well as Greyhound Park for greyhound racing that opened in 1972.
The World Solar Challenge race attracts teams from around the world, most of which are fielded by universities or corporations, although some are fielded by high schools. The race has a 20-years' history spanning nine races, with the inaugural event taking place in 1987. Adelaide hosted the 2012 World Bowls Championships at Lockleys Bowling Club, becoming the third city in the world to have held the championships twice, having previously hosted the event in 1996.
Dirt track speedway is also popular in Adelaide with three operating speedways. Adelaide Motorsport Park, located adjacent to the Adelaide International Raceway road racing circuit at Virginia ( north of the city centre) has been in continuous operation since 1979 after the closure of the popular Rowley Park Speedway. Gillman Speedway located in the semi-industrial suburb of Gillman, has been in operation since 1998 and caters to Motorcycle speedway and Sidecars, while the Sidewinders Speedway located in Wingfield is also a motorcycle speedway dedicated to Under-16 riders and has been in operation since 1978.
In 2016, backed by South Australia's Peregrine Corporation opened up a multi-purpose facility; a state-of-the-art motorsporting park and a hotel alongside its newer OTR service station outside a small township of Tailem Bend currently named The Bend Motorsport Park. Design for thrill seekers and rev-heads the facility currently host South Australia's second Supercars motoring event during a round in August.Stong crowd head to The Bend Auto Action 22 August 2023
Adelaide is home to the Great Southern Slam, the world's largest roller derby tournament. The tournament has been held biennially over Australia's Queen's Birthday holiday weekend since 2010. In 2014, and 2016 the tournament featured 45 teams playing in two divisions. In 2018, the tournament has expanded to 48 teams competing in three divisions. |

Adelaide | Transport | Transport
thumb|Adelaide's railway and tram network, served by the Adelaide Metro
Being centrally located on the Australian mainland, Adelaide forms a strategic transport hub for east–west and north–south routes. The city itself has a metropolitan public transport system managed by and known as the Adelaide Metro. The Adelaide Metro consists of a contracted bus system including the O-Bahn Busway, 7 commuter rail lines (diesel and electric), and a small tram network operating between inner suburb Hindmarsh, the city centre, and seaside Glenelg. Tramways were largely dismantled in the 1950s, but saw a revival in the 2010s with upgrades and extensions.
Road transport in Adelaide has historically been easier than many of the other Australian cities, with a well-defined city layout and wide multiple-lane roads from the beginning of its development. Adelaide was known as a "twenty-minute city", with commuters having been able to travel from metropolitan outskirts to the city proper in roughly twenty minutes. However, such arterial roads often experience traffic congestion as the city grows. (1.18MB)
thumb|left|The O-Bahn Busway tunnel passes under Rymill Park and serves the northeastern suburbs.
The Adelaide metropolitan area has one freeway and four expressways. In order of construction, they are:
The South Eastern Freeway (M1), connects the south-east corner of the Adelaide Plain to the Adelaide Hills and beyond to Murray Bridge and Tailem Bend, where it then continues as National Highway 1 south-east to Melbourne.
The Southern Expressway (M2), connecting the outer southern suburbs with the inner southern suburbs and the city centre. It duplicates the route of South Road.
The North-South Motorway (M2), is an ongoing major project that will become the major north–south corridor, replacing most of what is now South Road, connecting the Southern Expressway and the Northern Expressway via a motorway with no traffic lights. As of 2024 the motorway's northern half is complete, connecting the Northern Expressway to Adelaide's inner north-west; the section running through Adelaide's inner west and inner south-west will begin major construction in 2025 with completion estimated for 2031.
The Port River Expressway (A9), connects Port Adelaide and Outer Harbor to Port Wakefield Road at the northern "entrance" to the metropolitan area.
The Northern Expressway (Max Fatchen Expressway) (M2), is the northern suburbs bypass route connecting the Sturt Highway (National Highway 20) via the Gawler Bypass to Port Wakefield Road at a point a few kilometres north of the Port River Expressway connection.
The Northern Connector, completed in 2020, links the North South Motorway to the Northern Expressway. |
Adelaide | Airports | Airports
thumb|left|A Qatar Airways plane at Adelaide Airport with the city skyline in the background
The Adelaide metropolitan area has two commercial airports, Adelaide Airport and Parafield Airport. Adelaide Airport, in Adelaide's south-western suburbs, serves in excess of 8 million passengers annually. Parafield Airport, Adelaide's second airport north of the city centre, is used for small aircraft, pilot training and recreational aviation purposes. Parafield Airport served as Adelaide's main aerodrome until the opening of the Adelaide Airport in February 1955. Adelaide Airport serves many international and domestic destinations including all Australian state capitals.
Adelaide is also home to a military airport, known as Edinburgh Airport, located in the northern suburbs. It was built in 1955 in a joint initiative with the United Kingdom for weapon development. |
Adelaide | Health | Health
thumb|right|The University of Adelaide Health and Medical Sciences Building, located in the BioMed City precinct on North Terrace
Adelaide's two largest hospitals are the Royal Adelaide Hospital (RAH) in Adelaide Parklands, a teaching hospital affiliated with the University of Adelaide (800 beds), and the Flinders Medical Centre (580 beds) at Bedford Park, affiliated with Flinders University. The RAH also operates additional campuses for specialist care throughout the suburbs including the Hampstead Rehabilitation Centre (150 beds) at Northfield and the Glenside Campus (129 beds) for acute mental health services.
Other major public hospitals are the Women's and Children's Hospital (305 beds), at North Adelaide; the Queen Elizabeth Hospital (340 beds) at Woodville; Modbury Hospital (174 beds) at Modbury; and the Lyell McEwin Hospital (198 beds) at Elizabeth Vale. Numerous private hospitals are also located throughout the city, with the largest operators being not-for-profits Adelaide Community Healthcare Alliance (three hospitals) and Calvary Care (four hospitals).
In 2017, the RAH was relocated from the city's East End to a new AU$2.3 billion facility built over former railyards in the West End. The state-of-the-art hospital forms part of a new biomedical precinct called BioMed City that collocates the South Australian Health and Medical Research Institute (SAHMRI), the University of Adelaide Health and Medical Sciences building, the University of South Australia's Health Innovation Building, and the state's Dental Hospital. SAHMRI, with additional external funding, has built a $300 million second facility completed in 2024, which was intended to house the Australian Bragg Centre with Australia's first proton therapy unit. Construction is underway for the Women's and Children's Hospital to be relocated to the precinct adjacent the RAH by 2030.

The largest provider of community health care within Adelaide is the not-for-profit Royal District Nursing Service, which provides out of hospital care and hospital avoidance care. |
Adelaide | Energy | Energy
Adelaide's energy requirements were originally met by the Adelaide Electric Supply Company, which was nationalised by the Playford government in 1946, becoming the Electricity Trust of South Australia (ETSA). Despite significant public opposition and the Labor party's anti-privatisation stance which left the Liberal party one vote short of the numbers needed to pass the legislation, ETSA was privatised by the Olsen Government in 1999 by way of a 200-year lease for the distribution network (ETSA Utilities, later renamed SA Power Networks) and the outright purchase of ETSA Power by the Cheung Kong Holdings for $3.5 billion (11 times ETSA's annual earnings) after Labor MP Trevor Crothers resigned from the party and voted with the government.
The electricity retail market was opened to competition in 2003 and although competition was expected to result in lower retail costs, prices increased by 23.7% in the market's first year. In 2004, the privatisation was deemed to be a failure with consumers paying 60% more for their power and with the state government estimated to lose $3 billion in power generation net income in the first ten years of privatisation. In 2012, the industry came under scrutiny for allegedly reducing supply by shutting down generators during periods of peak demand to force prices up. Increased media attention also revealed that in 2009 the state government had approved a 46% increase in retail prices to cover expected increases in the costs of generation while generation costs had in fact fallen 35% by 2012. South Australia has the highest retail price for electricity in the country.
Privatisation led to competition from a variety of companies who now separately provide for the generation, transmission, distribution and retail sales of gas and electricity. Electricity generation comes from a range of technologies and operators. ElectraNet operates the high-voltage electricity transmission network. SA Power Networks distributes electricity to end users. The largest electricity and gas retailing companies are also the largest generating companies.
The largest fossil fuel power stations are the Torrens Island Power Station gas-fired plant operated by AGL Energy and the Pelican Point Power Station operated by Engie. South Australia also has wind and solar power and connections to the national grid. Gas is supplied from the Moomba Gas Processing Plant in the Cooper Basin via the Moomba Adelaide Pipeline System and the SEAGas pipeline from Victoria.
In 2011, South Australia generated 18% of its electricity from wind power, and had 51% of the installed capacity of wind generators in Australia.
Due to almost universal blackouts within the city during September 2016, the state worked with Tesla to produce the world's largest electricity battery at Hornsdale Power Reserve which has increased that state's electrical security to the extent in which large blackouts are no longer an event. |
Adelaide | Water | Water
thumb|An aerial view of Happy Valley Reservoir, 2007
The provision of water services is by the government-owned SA Water. Adelaide's water is supplied from its seven reservoirs: Mount Bold, Happy Valley, Myponga, Millbrook, Hope Valley, Little Para and South Para. The yield from these reservoir catchments can be as little as 10% of the city's requirements (90GL per annum) in drought years and about 60% in average years. The remaining demand is met by the pumping of water from the River Murray.
A sea-water desalination plant capable of supplying 100GL per annum was built during the 2001–2009 drought; however, it operated at about 8% of its capacity until 2019. In December 2018, the State and Federal Governments agreed to fund a $2m study to determine how the plant could be used to reduce reliance on river water, in an effort to help save the Murray River basin and mouth (including the Coorong) from further ecological damage. |
