James Dewey Watson, KBE (hon.), ForMemRS (born April 6, 1928) is an American molecular biologist, geneticist and zoologist, best known as one of the co-discoverers of the structure of DNA in 1953 with Rosalind Franklin, Maurice Wilkins and Francis Crick. Watson, Crick, and Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".[4]
After studies at the University of Chicago (B.S., 1947) and Indiana University (Ph.D., 1950), Watson did postdoctoral research to absorb chemistry with the biochemist Herman Kalckar in Copenhagen. Watson next worked at the University of Cambridge's Cavendish Laboratory in England, where he first met his future collaborator and friend Francis Crick.
From 1956 to 1976, Watson was on the faculty of the Harvard University Biology Department, promoting research in molecular biology.[4] From 1968 he served as director of Cold Spring Harbor Laboratory (CSHL) on Long Island, New York, greatly expanding its level of funding and research. At CSHL, he shifted his research emphasis to the study of cancer, along with making it a world leading research center in molecular biology. In 1994, he started as president and served for 10 years. He was then appointed chancellor, serving until 2007 [5] when he resigned his position after making controversial comments claiming a link between intelligence and geographical ancestry.[6][7][8][9][10] Between 1988 and 1992, Watson was associated with the National Institutes of Health, helping to establish the Human Genome Project.
Watson has written many science books, including the textbook Molecular Biology of the Gene[11] (1965) and his bestselling book The Double Helix[12] (1968) about the DNA structure discovery, reissued in a new edition in 2012 - The Annotated and Illustrated Double Helix edited by Alex Gann and Jan Witkowski.[13]
James Watson was born in Chicago, Illinois, on April 6, 1928, as the only son of Jean (Mitchell) and James D. Watson, a businessman descended mostly from colonial English immigrants to America.[4][14] His mother's father, Lauchlin Mitchell, a tailor, was from Glasgow, Scotland, and her mother, Lizzie Gleason, was the child of Irish parents from Tipperary.[15] Raised Catholic, he later described himself as "an escapee from the Catholic religion."[16] Watson said, "The luckiest thing that ever happened to me was that my father didn't believe in God."[17]
Watson grew up on the south side of Chicago and attended public schools, including Horace Mann Grammar School and South Shore High School.[4][18] He was fascinated with bird watching, a hobby shared with his father,[19] so he considered majoring in ornithology.[20] Watson appeared on Quiz Kids, a popular radio show that challenged bright youngsters to answer questions.[21] Thanks to the liberal policy of University president Robert Hutchins, he enrolled at the University of Chicago, where he was awarded a tuition scholarship, at the age of 15.[4][20][22]
After reading Erwin Schrödinger's book What Is Life? in 1946, Watson changed his professional ambitions from the study of ornithology to genetics.[23] Watson earned his B.S. degree in Zoology from the University of Chicago in 1947.[20] In his autobiography, Avoid Boring People, Watson described the University of Chicago as an idyllic academic institution where he was instilled with the capacity for critical thought and an ethical compulsion not to suffer fools who impeded his search for truth, in contrast to his description of later experiences. In 1947 Watson left the University of Chicago to become a graduate student at Indiana University, attracted by the presence at Bloomington of the 1946 Nobel Prize winner Hermann Joseph Muller, who in crucial papers published in 1922, 1929, and in the 1930s had laid out all the basic properties of the heredity molecule that Schrödinger presented in his 1944 book.[24] He received his PhD degree from Indiana University in 1950; Salvador Luria was his doctoral advisor.[20][25]
Originally, Watson was drawn into molecular biology by the work of Salvador Luria. Luria eventually shared a Nobel Prize for his work on the Luria-Delbrück experiment, which concerned the nature of genetic mutations. Luria was part of a distributed group of researchers who were making use of the viruses that infect bacteria, called bacteriophages. Luria and Max Delbrück were among the leaders of this new "Phage Group," an important movement of geneticists from experimental systems such as Drosophila towards microbial genetics. Early in 1948, Watson began his PhD research in Luria's laboratory at Indiana University.[25] That spring, he met Delbrück first in Luria's apartment and again that summer during Watson's first trip to the Cold Spring Harbor Laboratory (CSHL).[26][27]
The Phage Group was the intellectual medium where Watson became a working scientist. Importantly, the members of the Phage Group sensed that they were on the path to discovering the physical nature of the gene. In 1949, Watson took a course with Felix Haurowitz that included the conventional view of that time: that genes were proteins and able to replicate themselves.[28] The other major molecular component of chromosomes, DNA, was widely considered to be a "stupid tetranucleotide," serving only a structural role to support the proteins.[29] However, even at this early time, Watson, under the influence of the Phage Group, was aware of the Avery-MacLeod-McCarty experiment, which suggested that DNA was the genetic molecule. Watson's research project involved using X-rays to inactivate bacterial viruses.[30] He earned his Ph.D. in Zoology at Indiana University in 1950 (at age 22).
Watson then went to Copenhagen University in September 1950 for a year of postdoctoral research, first heading to the laboratory of biochemist Herman Kalckar.[4] Kalckar was interested in the enzymatic synthesis of nucleic acids, and he wanted to use phages as an experimental system. Watson, however, wanted to explore the structure of DNA, and his interests did not coincide with Kalckar's.[31] After working part of the year with Kalckar, Watson spent the remainder of his time in Copenhagen conducting experiments with microbial physiologist Ole Maaloe, then a member of the Phage Group.[32]
The experiments, which Watson had learned of during the previous summer's Cold Spring Harbor phage conference, included the use of radioactive phosphate as a tracer to determine which molecular components of phage particles actually infect the target bacteria during viral infection.[31] The intention was to determine whether protein or DNA was the genetic material, but upon consultation with Max Delbrück,[31] they determined that their results were inconclusive and could not specifically identify the newly labeled molecules as DNA.[33] Watson never developed a constructive interaction with Kalckar, but he did accompany Kalckar to a meeting in Italy, where Watson saw Maurice Wilkins talk about his X-ray diffraction data for DNA.[4] Watson was now certain that DNA had a definite molecular structure that could be elucidated.[34]
In 1951, the chemist Linus Pauling in California published his model of the amino acid alpha helix, a result that grew out of Pauling's efforts in X-ray crystallography and molecular model building. After obtaining some results from his phage and other experimental research[35] conducted at Indiana University, Statens Serum Institut (Denmark), CSHL, and the California Institute of Technology, Watson now had the desire to learn to perform X-ray diffraction experiments so he could work to determine the structure of DNA. That summer, Luria met John Kendrew, and he arranged for a new postdoctoral research project for Watson in England.[4] In 1951 Watson visited the Stazione Zoologica 'Anton Dohrn' in Naples.[36]
In mid-March 1953, using experimental data collected by Rosalind Franklin and Maurice Wilkins, Watson and Crick deduced the double helix structure of DNA.[4][37] Sir Lawrence Bragg, the director of the Cavendish Laboratory (where Watson and Crick worked), made the original announcement of the discovery at a Solvay conference on proteins in Belgium on April 8, 1953; it went unreported by the press. Watson and Crick submitted a paper to the scientific journal Nature, which was published on April 25, 1953.[38] This has been described by some other biologists and Nobel laureates as the most important scientific discovery of the 20th century.[citation needed] Bragg gave a talk at the Guy's Hospital Medical School in London on Thursday, May 14, 1953, which resulted in a May 15, 1953, article by Ritchie Calder in the London newspaper News Chronicle, entitled "Why You Are You. Nearer Secret of Life."
Sydney Brenner, Jack Dunitz, Dorothy Hodgkin, Leslie Orgel, and Beryl M. Oughton were some of the first people in April 1953 to see the model of the structure of DNA, constructed by Crick and Watson; at the time, they were working at Oxford University's Chemistry Department. All were impressed by the new DNA model, especially Brenner, who subsequently worked with Crick at Cambridge in the Cavendish Laboratory and the new Laboratory of Molecular Biology. According to the late Dr. Beryl Oughton, later Rimmer, they all travelled together in two cars once Dorothy Hodgkin announced to them that they were off to Cambridge to see the model of the structure of DNA.[39]
The Cambridge University student newspaper Varsity also ran its own short article on the discovery on Saturday, May 30, 1953. Watson subsequently presented a paper on the double-helical structure of DNA at the 18th Cold Spring Harbor Symposium on Viruses in early June 1953, six weeks after the publication of the Watson and Crick paper in Nature. Many at the meeting had not yet heard of the discovery. The 1953 Cold Harbor Symposium was the first opportunity for many to see the model of the DNA double helix.
Watson, Crick, and Wilkins were awarded the Nobel Prize in Physiology or Medicine in 1962 for their research on the structure of nucleic acids.[4][4][40][41] Rosalind Franklin had died in 1958 and was therefore ineligible for nomination.[37]
The publication of the double helix structure of DNA can be regarded as a turning point in science: human understanding of life was fundamentally changed and the modern era of biology began.[42]
In 1956, Watson accepted a position in the Biology department at Harvard University. His work at Harvard focused on RNA and its role in the transfer of genetic information.[43] At Harvard University, Watson achieved a series of academic promotions from assistant professor to associate professor to full professor of biology. Watson claimed, however, that he was refused a $1,000 raise in salary after winning the Nobel Prize.
He championed a switch in focus for the school from classical biology to molecular biology, stating that disciplines such as ecology, developmental biology, taxonomy, physiology, etc. had stagnated and could progress only once the underlying disciplines of molecular biology and biochemistry had elucidated their underpinnings, going so far as to discourage their study by students.
Watson continued to be a member of the Harvard faculty until 1976, even though he took over the directorship of Cold Spring Harbor Laboratory in 1968.[43]
Views on Watson's scientific contributions while at Harvard are somewhat mixed. His most notable achievements in his two decades at Harvard may be what he wrote about science, rather than anything he discovered during that time.[44] Watson's first textbook, The Molecular Biology of the Gene, set a new standard for textbooks, particularly through the use of concept heads—brief declarative subheadings.[citation needed] His next textbook was Molecular Biology of the Cell, in which he coordinated the work of a group of scientist-writers. His third textbook was Recombinant DNA, which described the ways in which genetic engineering has brought much new information about how organisms function. The textbooks are still in print.
In 1968, Watson wrote The Double Helix,[12] listed by the Board of the Modern Library as number seven in their list of 100 Best Nonfiction books.[45] The book details the sometimes painful story of not only the discovery of the structure of DNA, but also the personalities, conflicts and controversy surrounding their work. Watson's original title was to have been "Honest Jim", in that the book recounts the discovery of the double helix from his point of view and included many of his private emotional impressions at the time. The book changed the way the public viewed scientists and the way they work.[46][dubious ]
Some controversy surrounded the publication of the book. Watson's book was originally to be published by the Harvard University Press, but Francis Crick and Maurice Wilkins objected, among others. Watson's home university dropped the project and the book was commercially published.[47]

In 1968, Watson became the Director of the Cold Spring Harbor Laboratory. Between 1970 and 1972, the Watsons' two sons were born, and by 1974, the young family made Cold Spring Harbor their permanent residence. Watson served as the laboratory's director and president for about 35 years, and later he assumed the role of chancellor and then Chancellor Emeritus.
In his roles as director, president, and chancellor, Watson led CSHL to articulate its present-day mission, "dedication to exploring molecular biology and genetics in order to advance the understanding and ability to diagnose and treat cancers, neurological diseases, and other causes of human suffering."[48] CSHL substantially expanded both its research and its science educational programs under Watson's direction. He is credited with "transforming a small facility into one of the world's great education and research institutions. Initiating a program to study the cause of human cancer, scientists under his direction have made major contributions to understanding the genetic basis of cancer."[49] In a retrospective summary of Watson's accomplishments there, Bruce Stillman, the laboratory's president, said, "Jim Watson created a research environment that is unparalleled in the world of science."[49]
In October 2007, Watson was suspended following criticism of views on race and intelligence attributed to him,[50][51] and a week later, on the 25th, he retired at the age of 79 from CSHL from what the lab called "nearly 40 years of distinguished service".[49][52] In a statement, Watson attributed his retirement to his age, and circumstances that he could never have anticipated or desired.[53]
In 1990, Watson was appointed as the Head of the Human Genome Project at the National Institutes of Health, a position he held until April 10, 1992.[54] Watson left the Genome Project after conflicts with the new NIH Director, Bernadine Healy. Watson was opposed to Healy's attempts to acquire patents on gene sequences, and any ownership of the "laws of nature." Two years before stepping down from the Genome Project, he had stated his own opinion on this long and ongoing controversy which he saw as an illogical barrier to research; he said, "The nations of the world must see that the human genome belongs to the world's people, as opposed to its nations." He left within weeks of the 1992 announcement that the NIH would be applying for patents on brain-specific cDNAs.[55] (The issue of the patentability of genes has since been resolved in the US by the US Supreme Court; see Association for Molecular Pathology v. U.S. Patent and Trademark Office)
In 1994, Watson became President of CSHL. Francis Collins took over the role as Director of the Human Genome Project.
In 2007, James Watson became the second person[56] to publish his fully sequenced genome online,[57] after it was presented to him on May 31, 2007, by 454 Life Sciences Corporation[58] in collaboration with scientists at the Human Genome Sequencing Center, Baylor College of Medicine. Watson was quoted as saying, "I am putting my genome sequence on line to encourage the development of an era of personalized medicine, in which information contained in our genomes can be used to identify and prevent disease and to create individualized medical therapies".[59][60][61]
In 2014 Watson published a paper in The Lancet suggesting that biological oxidants may have a different role than is thought in diseases including diabetes, dementia, heart disease and cancer. For example, type 2 diabetes is usually thought to be caused by oxidation in the body that causes inflammation and kills off pancreatic cells. Watson thinks the root of that inflammation is different: "a lack of biological oxidants, not an excess", and discusses this in detail. One critical response was that the idea was neither new nor worthy of merit, and that The Lancet published Watson's paper only because of his name.[62] However, other scientists have expressed their support for his hypothesis and have proposed that it can also be expanded to why a lack of oxidants can result in cancer and its progression.[63]
Watson was a former member of the Board of Directors of United Biomedical, Inc., founded by Chang Yi Wang. He held the position for six years and retired from the board in 1999.[64]
In January 2007, Watson accepted the invitation of Leonor Beleza, president of the Champalimaud Foundation, to become the head of the foundation's scientific council, an advisory organ.[65][66]
Watson has also been an institute adviser for the Allen Institute for Brain Science.[67][68]
During his tenure as a professor at Harvard, Watson participated in several political protests:
An enduring controversy has been generated by Watson and Crick's unauthorized use of DNA X-ray diffraction data collected by Rosalind Franklin and Raymond Gosling. The controversy arose from the fact that some of Franklin's unpublished data were used without her consent by Watson and Crick in their construction of the double helix model of DNA.[37][72] Franklin's experimental results provided estimates of the water content of DNA crystals and these results were consistent with the two sugar-phosphate backbones being on the outside of the molecule. Franklin personally told Crick and Watson that the backbones had to be on the outside, which was a crucial piece of information because before then Linus Pauling and Watson and Crick had generated erroneous models with the chains inside and the bases pointing outwards.[24] Her identification of the space group for DNA crystals revealed to Crick that the two DNA strands were antiparallel.
The X-ray diffraction images collected by Gosling and Franklin provided the best evidence for the helical nature of DNA. Franklin's experimental work thus proved crucial in Watson and Crick's discovery. Watson and Crick had three sources for Franklin's unpublished data: 1) her 1951 seminar, attended by Watson,[73] 2) discussions with Wilkins,[74] who worked in the same laboratory with Franklin, 3) a research progress report that was intended to promote coordination of Medical Research Council-supported laboratories.[75] Watson, Crick, Wilkins and Franklin all worked in MRC laboratories.
Prior to publication of the double helix structure, Watson and Crick had little interaction with Franklin. Crick and Watson felt that they had benefited from collaborating with Wilkins. They offered him a co-authorship on the article that first described the double helix structure of DNA. Wilkins turned down the offer, a fact that may have led to the terse character of the acknowledgment of experimental work done at King's College in the eventual published paper. Rather than make any of the DNA researchers at King's College co-authors on the Watson and Crick double helix article, the solution that was arrived at was to publish two additional papers from King's College along with the helix paper.
Franklin may have never known the extent to which her unpublished data had helped in the double helix discovery. According to one critic, Watson's portrayal of Franklin in The Double Helix (written after Franklin's death when libel laws did not apply anymore) was negative and gave the appearance that she was Wilkins' assistant and was unable to interpret her own DNA data.[76] The latter accusation was indefensible since, e.g., Franklin herself told Crick and Watson that the helix backbones had to be on the outside, which was crucial to the elucidation of the helix since before this both Crick and Watson and Linus Pauling had independently generated flawed models with the chains inside and the bases pointing outwards.[24]
In his book The Double Helix, Watson described being intimidated by Franklin and that they were unable to establish constructive scientific interactions during the time period when Franklin was doing DNA research. In the book's epilogue, written after Franklin's death, Watson acknowledges his early impressions of Franklin were often wrong, that she faced enormous barriers as a woman in the field of science even though her work was superb, and that it took them years to overcome their bickering before he could appreciate Franklin's generosity and integrity.
A review of the handwritten correspondence from Franklin to Watson, located in the archives at CSHL, reveals that the two scientists later had exchanges of constructive scientific correspondence. In fact, Franklin consulted with Watson on her tobacco mosaic virus RNA research. Franklin's letters begin on friendly terms with "Dear Jim", and conclude with equally benevolent and respectful sentiments such as "Best Wishes, Yours, Rosalind". Each of the scientists published their own unique contributions to the discovery of the structure of DNA in separate articles, and all of the contributors published their findings in the same volume of Nature. These classic molecular biology papers are identified as: Watson J.D. and Crick F.H.C. "A Structure for Deoxyribose Nucleic Acid" Nature 171, 737-738 (1953),[38] Wilkins M.H.F., Stokes A.R. & Wilson, H.R. "Molecular Structure of Deoxypentose Nucleic Acids" Nature 171, 738-740 (1953),[77] Franklin R. and Gosling R.G. "Molecular Configuration in Sodium Thymonucleate" Nature 171, 740-741 (1953).[78]

Watson has often expressed provocative concepts and disparaging opinions of others within the realm of genetic research.
In his memoir, Avoid Boring People: Lessons from a Life in Science, Watson describes his academic colleagues as "dinosaurs", "deadbeats", "fossils", "has-beens", "mediocre", and "vapid." Steve Shapin in Harvard Magazine noted that Watson had written an unlikely "Book of Manners", telling about the skills needed at different times in a scientist's career; he wrote Watson was known for aggressively pursuing his own goals at the university. E. O. Wilson once described Watson as "the most unpleasant human being I had ever met", but in a later TV interview said that he considered them friends and their rivalry at Harvard old history (when they had competed for funding in their respective fields).[87][88]
In the epilogue to the memoir Avoid Boring People, Watson alternately attacks and defends former Harvard University president Lawrence Summers, who stepped down in 2006 due in part to his remarks about women and science. Watson also states in the epilogue, "Anyone sincerely interested in understanding the imbalance in the representation of men and women in science must reasonably be prepared at least to consider the extent to which nature may figure, even with the clear evidence that nurture is strongly implicated." [85]
In early October 2007, Watson was about to embark on a UK book tour to promote the memoir. He was interviewed by Charlotte Hunt-Grubbe at CSHL. In 1996 she had been a student there in a program in which Watson recruited students to live at his family home and work at CSHL for a year. Hunt-Grubbe had gone on to work for the Sunday Times Magazine; she was selected for the interview as she was one of the few women to have been mentored by him.
Hunt-Grubbe broached the subject of race and intelligence. Watson did not say in his memoir that race was a factor in his hypothesis of divergence of intellect between geographically isolated populations. The following is a transcript of that part of the interview: 'He says that he is "inherently gloomy about the prospect of Africa" because "all our social policies are based on the fact that their intelligence is the same as ours – whereas all the testing says not really", and I know that this "hot potato" is going to be difficult to address. His hope is that everyone is equal, but he counters that "people who have to deal with black employees find this not true". He says that you should not discriminate on the basis of colour, because "there are many people of colour who are very talented, but don't promote them when they haven't succeeded at the lower level". He writes that "there is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so"'.[89] Though other publications noted that the paper had '[kept] the profile sympathetic and place[d] the comments at the end of the piece',[90] the article was a public relations disaster for Watson. The Sunday Times Magazine editor Cathy Galvin noted, "It was important the reader understood Charlotte's relationship with Watson and her regard for him before exploring the explosive and unscientific territory of his opinions and history of statements about women, race, and abortion which have stirred so much controversy in the past."[90]
Watson's comments drew attention and criticism in the UK. Watson said his intention was to promote science not racism, but some of the UK venues canceled his appearances.[91] Watson canceled the rest of his tour.[92][93][94][95][96][97]
Because of the public controversy, on 18 October 2007, the Board of Trustees at Cold Spring Harbor Laboratory suspended Watson's administrative responsibilities. On October 19, Watson issued an apology; on October 25, he resigned from his position as chancellor.[7][8][9][10][98][99][100] In 2008, Watson was appointed chancellor emeritus of CSHL.[101] As of 2009, he continues to advise and guide project work at the laboratory.[102] In a 2008 BBC documentary, Watson said: "I have never thought of myself as a racist. I don't see myself as a racist. I am mortified by it. It was the worst thing in my life."[103] Some periodicals offered opinions on the matter[clarification needed].[104][105]
In 2014, he decided to auction off his Nobel prize medal in view of his diminished income after the 2007 incident[106] and to use part of the funds raised by the sale to support scientific research.[107] The medal sold at auction at Christie's in December 2014 for US$4.1 million. Watson is the first living recipient of the honor to auction the medal.[108]
The medal was subsequently returned to Watson by the purchaser, Russian tycoon Alisher Usmanov, who stated that Watson deserved the medal and that it was "unacceptable" that he should be compelled to sell it.[109]
Watson married Elizabeth Lewis in 1968. They have two sons, Rufus Robert Watson (b. 1970) and Duncan James Watson (b. 1972). Watson sometimes talks about their son Rufus, who suffers from schizophrenia. He wants to encourage progress in understanding and treatment of mental illness by determining how genetics contributes to it.[102] Watson is an atheist.[17][110] In 2003, he was one of 22 Nobel Laureates who signed the Humanist Manifesto.[111]

Among [Haurowitz's] students was Jim Watson, then a graduate student of Luria.
As we find the human genes whose malfunctioning gives rise to such devastating developmental failures, we may well discover that sequence differences within many of them also lead to much of the observable variation in human IQs. A priori, there is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our desire to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so.
'Because I was an "unperson" I was fired from the boards of companies, so I have no income, apart from my academic income,' he said.
Watson says he intends to use part of the money raised by the sale to fund projects at the universities and scientific research institutions he has worked at throughout his career.

Oligonucleotide microarrays, also called "DNA chips," are currently made by a light-directed chemistry that requires a large number of photolithographic masks for each chip. Here we describe a maskless array synthesizer (MAS) that replaces the chrome masks with virtual masks generated on a computer, which are relayed to a digital micromirror array. A 1:1 reflective imaging system forms an ultraviolet image of the virtual mask on the active surface of the glass substrate, which is mounted in a flow cell reaction chamber connected to a DNA synthesizer. Programmed chemical coupling cycles follow light exposure, and these steps are repeated with different virtual masks to grow desired oligonucleotides in a selected pattern. This instrument has been used to synthesize oligonucleotide microarrays containing more than 76,000 features measuring 16 microm 2. The oligonucleotides were synthesized at high repetitive yield and, after hybridization, could readily discriminate single-base pair mismatches. The MAS is adaptable to the fabrication of DNA chips containing probes for thousands of genes, as well as any other solid-phase combinatorial chemistry to be performed in high-density microarrays.

She can barely move after recovering from a broken ankle. It is painfully obvious that after weeks of sitting (non-weight-bearing orders for recovery of ankle) that she is so weak and hauling her pannus around is becoming next to impossible. She's in physical therapy daily, but I'm wondering if getting rid of this weight will help her walk again eventually. Any thoughts?

those who can no longer speak out about road safety. Thousands of cyclists
are injured or killed each year by careless drivers; it's possible for
both groups to use the roads without devastating families." Asked
why he approached the pro team he said, "I wanted to create more
awareness for all those injured or killed by drivers and I thought, what
better way than to reach out through cyclists everyone universally
respects?" Ride of Silence
founder Chris Phelan said, "I began the Ride of Silence to
show that each cyclist is a member of a larger community. We're doctors,
lawyers, co-workers, husbands, wives and parents. Each time a cyclist is
injured or, even worse, killed, that sends a ripple through the community.
Each accident hurts more than just one individual. The ride is held in
silence to reflect that loss. Cyclists are part of the fabric of every
community and the benefits of cycling, such as better health and reduced
pollution, should make it a priority for more people everywhere." The sponsor less ride is organized each year by volunteers. The 2008 ride was held at more than 300 locations, in 18 countries, on all 7 continents. It has come a long way from the first ride held in 2003, that ride was organised as a one-time event. But the Ride of Silence touched many and found universal support. It is now an annual event held on May 20th. This event is very close to the heart of CJ Farquharson, founder of WomensCycling.net and known around the world for her photography and coverage of professional women's racing. CJ herself was nearly killed in 2007, during the final stage of the Thuringen Rundfahrt, when the Chief Moto Marshall ploughed into the side of the moto she was travelling on. CJ was within 5cm of losing her left leg, it was severed below the knee in the accident with only 5cm of her calf muscle remaining intact. The impact also crushed both bones and her ankle, she had minor head injuries and major damage to ligaments in her right and right shoulder in the process. Coincidentally, this accident happened within 200m of the same spot, that took the life of Australian cyclist Amy Gillett in 2005 and seriously injured five her team mates when they were hit by a car. Safety on our
roads should be supported by all cyclist and drivers around the
world. Want to contact WomensCycling.net?

Colours & Material HeadLine Management Chair
Perforated leather |
HeadLine Management Chair is a sophisticated, distinguished version of HeadLine with fine leather upholstery. It responds to the ergonomic demands of today's computer-oriented workplaces by not only providing optimal support in the lumbar zone, but also extending it to the previously neglected areas of the shoulders, neck and head.
In an upright sitting position, the head is naturally balanced on the spinal column. However, when the sitter alters this position—thereby changing the parameters of a chair's supportive functions—the inevitable result is muscle strain in the neck and shoulders. A conventional office chair has a contoured backrest with a curve in the lumbar zone to support the sitter's torso. In the reclined position, however, the head is no longer aligned with the spine, forcing the shoulder and neck muscles to bear its weight. This results in strain and tension.
HeadLine Management Chair solves this problem: The flexible, elongated backrest is suspended from the frame at the critical points of the lower back and neck by means of articulated joints. In the upright position, most of the supportive function is focused on the lumbar zone. When the sitter leans back, the shoulders sink into the back panel and the upper backrest extension tilts forward to support the head. This prevents muscle strain in the neck and shoulder areas. Contrary to conventional office chairs, in which users find themselves gazing at the ceiling in the reclined position, HeadLine maintains a horizontal line of sight with the sitter's eyes directed toward the computer monitor.
HeadLine Management Chair is upholstered in high-quality leather. Fine perforations in the leather cover ensure that seating comfort is maintained even over prolonged periods of use.
The enduring quality of HeadLine is guaranteed by its superior design, materials and workmanship. Recycled aluminium comprises 53% of the chair's components. The remaining materials are 98% recyclable.
