albert moll ( 18621939 ) , sigmund freud ( 18561939 ) and magnus hirschfeld ( 18681935 ) were among the most influential sexologists of the twentieth century . after the death of the pioneer sexologists , the italian physician , anthropologist and writer paolo mantegazza ( 18311912 ) and the german  austrian psychiatrist richard von krafft - ebing ( 18401902 ) , the geheimer sanittsrat [ german privy councillor of health ] albert moll was regarded by many as the most competent specialist on sexual disorders in europe . today , however , he and his work are largely forgotten and overshadowed by freud and hirschfeld : freud is remembered as the founder of psychoanalysis and father of the psychoanalytical movement ; while hirschfeld is considered to be the mastermind of the first german homosexual movement and the weltliga fr sexualreform [ world league for sexual reform ] as well as the founder of the world s first institute for sexology . while elements of freudian psychoanalysis became part of common speech , some kind of hirschfeld - renaissance can be observed in germany and elsewhere . as a result , his views are discussed relatively widely , for example in the context of the debate on what is natural , social , epistemic , predisposed , essential or constructed with regard to gender and sexuality ; the transactions of the magnus hirschfeld 
 society , published since 1983 , are but one example . hitherto , only a small number of historians of medicine and sexologists have studied moll and his work . this is even more astonishing if one considers his wide - ranging ideas , interests and activities , as well as the sharpness of his criticism in academic debates . moll had received global recognition with his first book , der hypnotismus [ hypnotism ] . william james described it as  extraordinarily complete and judicious. 
  moll regarded himself as the pioneer of the nancy school of libeault and bernheim , and claimed to have introduced hypnotic and psychotherapeutic ideas into germany . he was indeed one of the first in the medical profession who tried to amalgamate psychology and scientific medicine . unlike hirschfeld , he repeatedly objected to the somatic and causal thinking in medicine and sexology , for example with regard to eugenics or the transplantation of the testicles from heterosexual men to homosexuals as a cure for homosexuality . medical psychology , on which he published a journal with the publishing company ferdinand enke between 1909 and 1924 . he also encouraged health insurance companies to extend cover to psychotherapy for the very first time in 1919 . it would probably not be an exaggeration to call moll the founder of medical psychology in germany , 
  an achievement unknown to most medical psychologists today . in 1891 , before hirschfeld , moll produced a monograph on sexual inversion [ contrre 
 sexualempfindung ] , 
  the contemporary term used for homosexuality , and in 1897 , before freud , he published one of the first substantial scientific works on what is termed today as heterosexuality. 
  his still - readable rztliche ethik [ medical ethics ] was published in 1902 and his handbuch der sexualwissenschaften [ handbook of 
 sexual sciences ] in 1912 . 
  given the task of editing richard von krafft - ebing s famous psychopathia sexualis together with the philosopher max dessoir ( 18671947 ) he fought the occult sciences and their protagonists , often as a much - dreaded expert witness in court  see also the papers by heather wolffram and andreas sommer in this issue . the british sexologist henry havelock ellis ( 18591939 ) , who , unlike moll and freud , did not exhibit vanity and become involved in rivalries , cited moll more often than any other expert , including krafft - ebing , the sexologist iwan bloch ( 18721922 ) , freud or hirschfeld . it is debateable who would have represented an enlightened scientific position more convincingly if one looks at their responses to key issues at the time : concepts of the libido sexualis and infant sexuality ; the relationship between normal and abnormal sexuality ; problems of the aetiology of sexual pathologies , including degeneration ; the question of homosexuality , including paragraph 175 of the german penal code ; and the seduction hypothesis ; questions of women s rights , including the practical aspects of the protection of mothers ; psychotherapeutic versus somatic treatment of sexual dysfunction ; the relationship between medicine and psychology ; medical ethics ; issues of applied eugenics , etc . often moll was  prematurely and unread  labelled as a reactionary , even though he had commented on these issues very early and usually in a fairly differentiated manner , indeed often more independently and far - sightedly than hirschfeld . in 1902 , for example , moll published his work on medical ethics patient relationship as a contract with the goal to maintain or restore the patient s health . the publication was initiated by the scandals caused by human experimentation at the time . moll mentioned , for example , cases where doctors had allegedly infected prostitutes with syphilis . he criticised such behaviour and also appealed to doctors to stop the vain fighting for priorities . he urged for self - constraint , as well as the appreciation of achievements in other nations . doctors should decline commissioned reports : if the documentation was insufficient ; in cases where only a formal reply but no substantial and therefore truthful response could be given ; if  one s own expertise was insufficient ; or if the report  was supposed to serve immoral ends. 
  with regard to medical journals , he pointed to the problematic influence of commercial interest . thus , moll discussed ethical issues in medicine more than one hundred years ago , and those that are still relevant today . his attitudes towards eugenics and so - called racial hygiene were also remarkable , when it is taken into account how many scientists , especially sexologists of all political convictions , could not resist the promise of  breeding and improving humankind . a few years before hitler came to power , moll wrote : the fact that we find so many valuable people , despite the hereditary burden , is caused by regeneration in countless cases , not progressive degeneration  . [ t]his explains that we can hardly ever say something about the condition of offspring with any certainty at all  . it is necessary to point out such things , because our amateur eugenicists today are already sprawling too much . the fact that we find so many valuable people , despite the hereditary burden , is caused by regeneration in countless cases , not progressive degeneration  . [ t]his explains that we can hardly ever say something about the condition of offspring with any certainty at all  . it is necessary to point out such things , because our amateur eugenicists today are already sprawling too much . moll also argued that the problem of inadequate parenting and education had not received sufficient attention :  provide me with ten random people from the street and i will diagnose in nine of them the same degeneration as in a culprit  . if we ask us now which options we have for practical eugenics , it will primarily be prevention  . castration has today generally been abandoned. moll did not advocate practical eugenics as a way to  make humankind better and instead favoured social mobility . members of the middle and working classes should be allowed to  add fresh blood from below to the upper classes , which were  partially degenerated. if this was accomplished , a lot more would be gained for the improvement of our people than if a few thousand individuals were robbed of their fertility , even though actually no one knows why. 

  in his handbook of sexology , moll expressed the hope that plans for sterilisation programmes in germany would  not be implemented and that our race - improvers do not get too much influence on our legislation. 
  when they had obtained such influence and had begun legally to sanction compulsory sterilisation , especially of habitual offenders , he stated  that we have no scientific indication whatsoever. 
  on the other hand , the already exiled hirschfeld wrote in august 1933 : for once it is not certain at all that the national socialists act solely on eugenic motives . one has to fear that they will use sterilisation not so much to  breed the race  , but to destroy their enemies. one of the great rivalries moll encountered in his academic life was his relationship with sigmund freud . freud entered the stage as a sexologist in 1905 with his drei 
 abhandlungen zur sexualtheorie [ three essays on the theory of sexuality ] , a work of just eighty - three pages , but still discussed today . in broad strokes he dismissed most of what sexology the first footnote of his epochal work read : the accounts in the first treatise are extracted from the known publications by v. krafft - ebing , moll , moebius , havelock ellis , ncke , v. schrenk - notzing [ correctly : schrenck - notzing ] lwenfeld  eulenburg , j. bloch [ correctly : i. bloch ] as well as the works in the jahrbuch fr sexuelle zwischenstufen [ yearbook for sexual 
 intermediate stages ] , published by m. hirschfeld . since in these all the other literature on the topic the accounts in the first treatise are extracted from the known publications by v. krafft - ebing , moll , moebius , havelock ellis , ncke , v. schrenk - notzing [ correctly : schrenck - notzing ] lwenfeld  eulenburg , j. bloch [ correctly : i. bloch ] as well as the works in the jahrbuch fr sexuelle zwischenstufen [ yearbook for sexual 
 intermediate stages ] , published by m. hirschfeld . since in these all the other literature on the topic is listed comprehensively , i could spare myself detailed references . 

  through this arrogant but genial move , freud avoided all previous debates and terminology in the field : phantasia morbosa , fisiologia della donna , dgnresence , sense 
 gnsiques , zones rognes , auto - erotism , erotic symbolism , anthropologia sexualis , libido , kontrektationstrieb [ contrectation drive ] and detumeszenztrieb [ detumescence drive ] , psychopathia sexualis , kontrre sexualempfindung [ sexual inversion ] , neurasthenia 
 sexualis , aphrodisia and anaphrodisia , mutterschutz [ protection of mothers ] and  freie 
 liebe [  free love ] , frigidity , clitoridectomy , prostitution , venereal diseases , malthusianism , etc . he did not mention any of the works of his predecessors  neither the medical thesis produced the physician hermann joseph lwenstein in 1823 , nor the monograph by the physician joseph hussler published in 1826 . he also did not mention the first psychopathia sexualis by the austrian physician heinrich kaan ( 181693 ) , who came up with a theory that linked a functional - hydraulic idea of the sexual drive called nisus with fantasy , especially a furious phantasia morbosa , which predisposed humans to sexual excess . freud also did not mention the works by the french psychiatrist paul moreau de tours ( 18441908 ) and the russian physician benjamin tarnowsky ( 18371906 ) . strangely enough , even landmark publications such as paolo mantegazza s gli amori degli uomini [ the sexual relations of mankind ] as well as auto - erotism and the sexual impulse in women by havelock ellis remained unacknowledged . if not any of these works , freud should at least have had to discuss one : moll s libido sexualis , published in 1897 . 
  at a theoretical level , moll went far beyond what krafft - ebing and other sexual pathologists , who had been influenced by augustin morel s ( 18091873 ) hypothesis of degeneration , had conceptualised . furthermore , he anticipated many of the sexual theories later claimed by freud and psychoanalysts to be their inventions . he explicitly discussed  like havelock ellis shortly after  the  normal sexual drive , on which hitherto  hardly any in - depth studies have been published. 
  he did not regard hereditary heterosexuality and inherited meaningful drives as self - evident , 
  and assumed a latent homosexuality of normal individuals as well as a latent heterosexuality of homosexuals , 
  and he argued for the abolition of paragraph 175 of the german penal code , which criminalised homosexual acts . 
  according to moll , the sexual drive , both normal and perverse , 
  was a combination of two elements : a  detumescence drive , which was  to be understood as an organic urge to release secretion , 
  and a contrectation drive , which induced  physical and spiritual attraction. 
  moll thought that a natural drive to procreation in humans was  not very noticeable anymore. 
  in general , human drives should be best understood in evolutionary terms ; 
  for example , he discussed in great detail the degeneration of the sense of smell in humans , 
  a question which also preoccupied freud as  organic suppression [ organische verdrngung ] and  abandoned 
 erogenous zones [ aufgelassene erogene zonen ] . it is worthwhile noting that moll , like ernest chambard ( 18511900 ) and other french authors , such as the physician charles fr ( 18521907 ) and the psychologist alfred binet ( 18571911 ) , had already used the term erogenous centres , or zones [ zones 
 rognes ] . empirical attention to sexual responses , voluptuousness and emotions of love in children , and gave a sketchy description of what was later to become the oedipus complex :  attraction to the other sex with all signs of voluptuousness appears long before puberty . i know of cases , where attraction to the other sex , undeniably caused by the sexual drive , could be observed at the age of five or six. 

  while  the sexual contrectation drive can appear before the genitals are mature , 
  so can the detumescence drive , which was also attributed to the female sex , even though there was no secretion equal to male semen . the sensation was  a kind of voluptuous feeling , a kind of tickle 
  at the genitalia ; erections appeared  a long time before puberty , 
  masturbation was observed in children as young as one or two years of age . 
  with regard to healthy sexuality , it was most remarkable that moll not only made theoretical assumptions , but also sought to prove every claim by case studies . thus , it does not come as a surprise that moll had a significant influence on freud s theories of sexuality and his terminology : from the phylogenetic and ontogenetic dynamics of the libido sexualis  which was previously thought to be static  the nexus of heredity and acquired traits ; the inextricably linked homosexuality and heterosexuality ; the in - no - way monolithic sexual drive ; to the pre - pubertal sexuality of boys and girls . this has plausibly been demonstrated by sulloway with freud s heavily annotated copy of moll s libido 
 sexualis . at least since 1905 , freud and moll had been engaged in a dispute about priority . freud s unconscious is , in the early works , according to steyerthal , nothing but the subconscious of dessoir and moll. 
  meanwhile , freud was less than impressed by moll after he had convinced himself that moll had plagiarised him and disputed his priority on childhood sexuality , which , after all ,  even if it might sound strange , was discovered by him , freud. 
  however , this did not just sound strange but was plainly wrong . as freud knew , but would not acknowledge publicly , moll had already , in 1897 , discussed  normal child sexuality , not only in passing , but effectively  discovering it in a systematic way , see also the contribution by lutz sauerteig in this volume . when the wiener psychoanalytische 
 vereinigung [ viennese psychoanalytical society ]  discussed moll s book das sexualleben des kindes [ the sexual life of the child ] , his allegedly bad character was frequently referred to . hirschfeld has already complained about him bitterly . he is a pedantic , malicious , narrow - minded character . he does not utter one clear opinion. 
  the meeting was so hostile that not a single one of moll s ideas received any form of acclaim . yet clear opinion was made up out of thin air . in his retrospective reflection on his own life , however , freud received me with the words :  attacks like yours no one has ever directed against me so far . you accuse us of forging patient records. to prove this he took out a copy of my book on the  sexual life of the child and quite agitated showed me the section in the book . 

  after this visit by moll , freud wrote a letter to jung , dated 16 may 1909 :  in short , he is a beast , basically not a doctor ; he has the intellectual and moral constitution of a pettifogger  . he has polluted my room like the devil himself , and i have not   put him in his place firmly enough . now , of course , we have to expect the nastiest attacks from him. 

  i sent in my card . however , freud received me with the words :  attacks like yours no one has ever directed against me so far . you accuse us of forging patient records. to prove this he took out a copy of my book on the  sexual life of the child and quite agitated showed me the section in the book . 

  yet the disciplinary differences between sexology on the one hand and psychoanalysis on the other reached beyond personal rivalries and animosities . historically , psychoanalysis has separated itself from sexology along the lines of the differentiations of unconscious and conscious , internal fantasy and external reality , structure and symptom , experience and behaviour , latency and manifestation . to put it bluntly : affirmative psychoanalysts are more than happy if the polymorph perverse disposition remains an abstraction , while affirmative sexologists are fascinated when perversions manifest themselves in manifold ways . most sexologists could not accept that subjects were denied their own reason , the noble goal of the bourgeoisie ; it was incommensurable , according to the elaborate teachings of freud . early on , freud saw the  inhibited intentions contained in a twilight zone , where they were leading an  unimagined existence   until they emerge as a spook. 
  this spook was , by freud , set against the noble ideals , the free will and self - conscious reason , which were essential to sexologists such as iwan bloch or albert moll . according to freud , the successful behaviour of the bourgeoisie was not only based on the renunciation of basic drives , which was also called for by the leading sexologists at the time , but equally on the repression of desires and inhibition of thoughts . it is well known that freud claimed  that the ego was not the master of its own house. 
  he called it the  third mortification of self - love , which had followed as the psychological mortification after the cosmological mortification at the hands of copernicus and the biological mortification by darwin . neither the old sexologists nor freud could foresee that theodor w. adorno ( 19031969 ) would add a fourth mortification when he found that the transcendental subject was unconscious ( bewusstlos ) , 
  and that with his archaeology , michel foucault ( 19261984 ) would at the same time bet all his money  that man vanishes like a face in the sand at the shore of the sea. the relationship between hirschfeld and moll was also poisoned and controversial in professional matters early on . moll came from a family of merchants in lissa / posen , hirschfeld from a family of doctors in kolberg / pomerania . both belonged to the same generation , grew up as jews in similar socio - economic circumstances . both studied medicine and travelled the world . both distanced themselves from judaism ; in doing so moll converted to lutheran protestantism , was baptised in 1895 and left the jewish congregation in 1896 . 
  according to their writings , neither of them married and neither had , as far as we know , any children . both published their first sexological work on homosexuality ; 
  spent their most productive years in berlin ; worked successfully outside the institutional setting of the university ; were unsympathetic to freud s psychoanalysis ; and held on to their patriotism and scientific worldview to the bitter end . moll died , humiliated by the nazis , in 1939 in berlin , hirschfeld died , exiled by the nazis , in 1935 in nizza . both belonged , without doubt , to the most influential sexologists of the past century . moll held the title of a geheimer sanittsrat [ privy councillor of health ] and saw himself as an  objective truth - finder , who was in pursuit of pure science , without any presuppositions or political interests . hirschfeld , however , was a straightforward , hands - on and not - so - privy councillor of health [ sanittsrat ] . on the one hand , he also regarded science as the ultimate form of reason and source of justice  hirschfeld s motto was  per scientiam 
 ad iustitiam [ through science to justice ] , yet on the other hand , he was pragmatic , mediating , had the common touch , was able to bend the rules of the medical profession , and directly to link science with everyday life . in other words hirschfeld never wrote about his own sexual orientation , probably to avoid giving ammunition to his enemies which they could use to destroy his existence . 
  in public , he was frequently labelled  homosexual ; a crude simplification which ignores subtleties and personal preferences , though it was also used by his friend karl giese in private conversations . however , such simplifications are necessary in order to acknowledge hirschfeld s scientific  political position today  in this case , in relation to the bachelor moll , whose sexual orientation can only be guessed at . as a scholar , moll took sides with the  first and , occasionally , the  second gender , while the reformer hirschfeld mainly fought for the time and again , moll alleged that hirschfeld had a  problematic nature and accused him of political agitation . although we can only speculate about personal animosities and rivalries , it is quite likely that moll rejected hirschfeld because the latter was abnormal , and hence speaking out of self - interest when he took the stage and barricades for the third , fourth and fifth gender , . how should such a person , unmanly , soft , effeminate , and an object of science himself , become the protagonist of sincere and objective research , treat patients in an unprejudiced manner and impartially examine sex offenders ? the personal involvement and subjectivity of the latter might well have disgusted the pure privy councillor . on top of all this , challenged moll s leadership and expertise in a specific area , in particular , as an expert witness in court , despite the fact that moll had published the first modern monograph on homosexuality. 

  it was not until 1905 that it became more than obvious how irreconcilable moll s and hirschfeld s personalities and scientific positions were . previously , moll had been one of the first to sign the petition by hirschfeld and the wissenschaftlich - humanitres komitee [ scientific  humanitarian committee ] to the german parliament , which envisaged legal equality of homo- and heterosexual acts between persons over the age of sixteen . 
  before the turn of the century , moll had emphasised the changes in customs and legislation  over the course of time and had accused the advocates of legislation against homosexuality of hypocrisy and encouragement of blackmail , and particularly of arbitrariness and irrationality : either one punishes by change of legislation homosexual acts between women , as well as all kinds of obscene activities between men , which are today not covered by the term unnatural fornication , and also all unnatural forms of satisfaction between man and woman , or one allows adult men to do sexually to each other whatever they want within their own walls , as long as they do not violate the rights of a third party . either one punishes by change of legislation homosexual acts between women , as well as all kinds of obscene activities between men , which are today not covered by the term unnatural fornication , and also all unnatural forms of satisfaction between man and woman , or one allows adult men to do sexually to each other whatever they want within their own walls , as long as they do not violate the rights of a third party . a year later moll had a paper published in hirschfeld s jahrbuch fr sexuelle 
 zwischenstufen [ yearbook for sexual intermediate stages ] , in which he tried to argue factually against the committee : objectivity was a rarity ; people did not tend to perceive their own actions as pathological and reprehensible . when homosexuals claimed that they had always felt as they did , it had to be pointed out that everyone preferred to  remember what was of particular interest to him. something natural was not necessarily healthy . something acquired did not necessarily make them guilty . from a medical point of view , guilt or antipathy treatment of homosexuality was necessary because in adults it was  a definitely pathological phenomenon. it was compared to malformations such as the cleft palate , therefore not to be described as morbid , but as abnormal and pathological . for the  conversion of the homosexual sex drive psychological treatments such as self - education and suggestion were most favourable . visits to brothels should be advised against :  i have to admit that to me homosexuality still appears to be the lesser evil compared to an infection with syphilis. there was no established treatment , and in many cases it was advisable to refrain from the treatment of homosexuality , but not the homosexual , who was  often enough not a healthy person in general. in conclusion , moll advised  the decently thinking homosexual to  occlude himself to the praises that some exalted homosexuals sang on homosexuality. then they could count on  getting sympathy from among the heterosexuals and on destroying prejudices . however , this can not be achieved if homosexuals represent their disposition as the virtually perfect , which is neither of concern to the doctor nor to the judge. 

  two years later moll wrote  and this was cited by hirschfeld with satisfaction when he was vilified in public : 

 particularly agreeable is the matter - of - fact manner in which the objections of the opponents are fought . everyone who wants to support the movement for the abolition of paragraph 175 of the imperial penal code can only be advised to continue on the current path . sometimes otherwise their only other option would be : they would have to try to reach their goals over a mountain of corpses . particularly agreeable is the matter - of - fact manner in which the objections of the opponents are fought . no scolding like it can sometimes be found even in scientific journals  . everyone who wants to support the movement for the abolition of paragraph 175 of the imperial penal code otherwise their only other option would be : they would have to try to reach their goals over a mountain of corpses . some senior civil servant or influential politician , who thoroughly disdained homosexuals as  the most sordid scum in the world , might be surprised because suddenly his son or his friend , such a good and marvellous person , was found to be among those engaged in same - sex relationships . therefore , moll regarded it as even more laudable that the homosexuals had decided to agitate factually. this agitation had already led to successes , which he applauded . in conclusion , he stated that everyone who worked on homosexuality  not only had to know , but also study thoroughly the yearbook . moll s  period of involution [ involutionsperiode ] , as hirschfeld phrased it in his autobiographical reflections on the homosexual movement , which were published in the early 1920s , thus had  then not yet set in. 

  later , moll attacked hirschfeld time and again with increasing ferocity , especially with regard to issues of homosexuality . poison for every homosexual who was interested in  cure , and was worried about the seduction of young men . he thought the  danger of breeding homosexuality   much higher than at the time when he had signed the petition of the scientific  humanitarian committee . hence , he criticised , in albert eulenburg s  a german physician and sexologist ( 18401917 )  enzyklopdie that  pure scientific discussions were joined by fomenting interests , which are mainly represented by the so - called scientific  humanitarian committee , whose mastermind is magnus hirschfeld. allegedly , this committee had not only set itself the task of scientific research into the sexual intermediate stages [ sexuelle zwischenstufen ] , but also the abolition of paragraph 175 : thereby members of the committee were led to emphasise agitation and interpret or manipulate the findings of science according to their interest . one could justifiably argue that the committee has recently caused offence in wide circles and occasionally given the impression as if the glorification of homosexuality was essential . thereby members of the committee were led to emphasise agitation and interpret or manipulate the findings of science according to their interest . one could justifiably argue that the committee has recently caused offence in wide circles and occasionally given the impression as if the glorification of homosexuality was essential . such developments had to be opposed as well as the assumption that something hereditary could not be influenced . even if one felt greatest pity with the  victims of the paragraph 175 ,  science  could not allow itself  to be dominated by this. how much effort was made to  manipulate the facts moll discussed in detail , with the help of a statistic hirschfeld had used to identify  the percentage of homosexuals. 
  yet , subsequently , he emphasised again that thorough scientific studies had been published in the yearbook for sexual intermediate 
 stages . internationaler kongre  fr sexualforschung [  first international conference for sex research ] , which he organised from 10 to 16 october 1926 in berlin , was sabotaged  from a certain direction both domestically and abroad . 
   the intellectual initiator i know , wrote moll : it is the same figure who one day pushed into my consulting room to ask me  to be good again. at the time i explained to him unmistakably that it was not a matter of  being good again , but serious concerns i had about his character  . attempts to disrupt the conference failed , but continued even during the conference , and also afterwards this figure still tried to debase the conference : the conference which was the first international scientific conference since the start of the war on german soil , but also the very first international scientific conference for sex research . it is the same figure who one day pushed into my consulting room to ask me  to be good again. at the time i explained to him unmistakably that it was not a matter of  being good again , but serious concerns i had about his character  . attempts to disrupt the conference failed , but continued even during the conference , and also afterwards this figure still tried to debase the conference : the conference which was the first international scientific conference since the start of the war on german soil , but also the very first international scientific conference for sex research . 

  in the following paragraph mr magnus hirschfeld was mentioned ; no doubt , he was  the same figure. moll alluded to hirschfeld s  character and  its problematic nature. 
  whether this referred to professional , commercial or sexual  misconduct remained unclear . factual , can be seen in the following sentence :  who does not understand the difference [ between ] a conference for sexual reform and a conference for sex research , is lost to science. 
  in moll s eyes , hirschfeld was an agitator who was  dangerous to public safety. 
  therefore , moll was also convinced that he had organised the very first scientific conference for sex research . this conference was supported by the internationale gesellschaft fr sexualforschung [ international society for sexual research , hereafter ingese ] , which had been founded at the end of 1913 and was dominated by the german economist julius wolf ( 18621937 ) , moll , and the german sexologist max marcuse ( 18771963 ) . ingese distanced itself from the rztliche gesellschaft fr sexualwissenschaft und 
 eugenik [ medical society for sexual science and eugenics ] , which had been founded in early 1913 , in which albert eulenburg , magnus hirschfeld and iwan bloch dominated . the ingese conference was indeed international and very scientific. 
  yet hirschfeld had already organised a big conference  on german soil five years earlier in 1921 , the  1 . internationale tagung fr sexualreform auf 
 sexualwissenschaftlicher grundlage [  first international conference for sexual reform on sexological basis ] , 
  which moll neither recognised as  scientific nor as  international , and probably out of resentment continuously postponed to 1922 . moll fiercely rejected speculation that hirschfeld had not been invited to the ingese conference because he represented , in contrast to himself ,  the more radical view. if the accusers were right , the conference ( would ) have been tendentious ; a terrible thought for the privy councillor of health . after all , thirty - five years ago , in 1891 , he had  argued fiercely against paragraph 175 , when it was still  very much frowned upon to advocate the  liberation of homosexuals. when the bund fr 
 mutterschutz [ association for the protection of mothers ] was founded he had been one of the first members ; also , with regard to the question of women s rights , he had  when it was not modern yet made his views  clear in the most definite way. all these differences between himself and hirschfeld , moll claimed , were constructed . therefore a plainly spoken word : he was not invited because it had to be assumed after certain statements that important figures would not have attended the conference if hirschfeld had received an invitation . yet the reason is not that mr magnus hirschfeld has a more radical view , but because many serious scientists do not regard him as an objective pursuer of truth , since  he does not approach science without presuppositions , but  confuses agitation with science . additionally , another reason for not inviting magnus hirschfeld was his problematic nature , on this i have a lot of material , which i am not prepared to publish today and without compulsion . therefore a plainly spoken word : he was not invited because it had to be assumed after certain statements that important figures would not have attended the conference if hirschfeld had received an invitation . yet the reason is not that mr magnus hirschfeld has a more radical view , but because many serious scientists do not regard him as an objective pursuer of truth , since  he does not approach science without presuppositions , but  confuses agitation with science . additionally , another reason for not inviting magnus hirschfeld was his problematic nature , on this i have a lot of material , which i am not prepared to publish today and without compulsion . when the nazis came to power in germany , moll did not carry out his threat to publish this  material , but did something more terrible . on 31 january 1934 he wrote a letter to gustave roussy ( 18741948 ) , dean of the medical faculty in paris , and sent a copy to the german foreign secretary . on 9 february 1934 the nazi minister had his  most profound thanks sent to moll for his friendly. 
  as a matter of fact it was a denunciation , which was intended to prevent hirschfeld from building a new existence in his french exile . in his letter to gustave roussy , moll claimed that hirschfeld did not have to leave germany because of the persecution of the jews or for other political reasons . always had such a bad reputation that he would not have been accepted , even in the professional body  where otherwise every untainted doctor finds admittance. 
  additionally , he described him as an opportunist who had his social democratic convictions  discovered only on 9 november 1918 , the day of the revolution in berlin , whereas he had been a strict militarist before. 
  now , however , he acted  as the persecuted martyr. moll wrote : under these circumstances i regard it as my duty   to make you aware of these facts , so that dr magnus hirschfeld can not present himself in respectable french scientific circles under the banner of the persecuted israelite and social democrat , who had to leave germany because of such persecution . as i am told , he has already made this attempt in france . 
  under these circumstances i regard it as my duty   to make you aware of these facts , so that dr magnus hirschfeld can not present himself in respectable french scientific circles under the banner of the persecuted israelite and social democrat , who had to leave germany because of such persecution . moll did not forget to mention his life - long  love for french psychology and his contacts with eminent french politicians and scientists , from his friend pol bouin ( 18701962 ) , professor of histology in strasbourg , who had advised him to write the letter , to the politician duard herriot ( 18721957 ) , and jean - martin charcot ( 182593 ) . he finished his letter with the invitation  to use these lines in any suitable way. so much malice , one can assume , was founded in hatred , disdain , patriotism , sense of honour , belief in science , or more general blindness . medical qualities have been celebrated by the medical historian heinz goerke because he had been a champion of high ethical standards in the medical profession , 
  would use denunciation . apparently , moll defended his highest values : patriotism , honour , science . for him , hirschfeld not only discredited their shared scientific interests , which were struggling for acceptance anyway , he also damaged the reputation of the fatherland abroad , particularly in france , to whose scholars moll owed so much , according to himself . in this situation , the impulse to divert damage from fatherland and science went hand - in - hand with ignorance about the political realities and certainly about the necessity to adapt to the new powers . moll had  always proved his german - nationalist patriotism in word and deed and joined the far - right deutsche vaterlandspartei [ german fatherland party ] in 1917 . 
  according to a membership card which can be found in moll s papers , and which has been recovered by winkelmann , 
  he was indeed a member of the party which was founded by kapp and von tirpitz in 1917 but disbanded in december 1918 . in 1927 , moll emphasised : i do not belong to any political party. when he had been invited by the deutsche volkspartei [ german people s party ] to join , he refused because this party had done nothing  to make the masses of workers national. 
  in the german people s party , which was founded by the banker and politician hjalmar schacht ( 18771970 ) , gustav stresemann ( 18781929 ) and others at the end of 1918 , it was mainly followers of the former nationalliberale partei [ national liberal party ] that came together . moll stated that he did not join this party because he did not want to lose his academic freedom of speech and the ability to talk , for example , in front of the unabhngige sozialdemokraten [ independent social democrats ] , which he had done previously . in his autobiographical reflections he insisted that he had never been a social democrat ,  not even a democrat ; his position had always rested  on the grounds of the old national liberal party of benningsen. 
  to his fatherland , which had  given him so much when it was happy , he of course remained faithful , especially  during unfortunate times. 

  hence , during the great war he took care of the replacements for doctors who had been conscripted , the training of red cross assistants , the organisation of military hospitals , and the provisions for the civilian population . when two doctors , whom he had asked to join his kriegsausschuss fr volksernhrung [ war committee for people s nutrition ] , said that they first had to talk to their parties , he was disgusted . instead he was approached by the auswrtige amt [ foreign office ] , the reichskolonialamt [ imperial colonial office ] , oberkommando in 
 den marken [ the high command of the marken ] and the groer generalstab [ general staff ] , for which he also worked on issues of psychological warfare . he was equally hostile to pacifism as he was to expert opinions given out of courtesy . apparently , when scheidemann declared the republic ,  even though he had been permanent secretary and therefore an imperial civil servant and given his oath of loyalty , 
  moll s universe collapsed . yet he stuck to his principles , be it as mediator between the arbeiter- und soldatenrat [ workers and soldiers council ] and the war ministry when he organised a militia [ volkswehr ] against the spartacists , or when he gave a man  asylum and protection , who played a prominent role in the november revolution but later feared  an arrest  la liebknecht. 

  this german nationalist and incorruptible man , who had founded and presided over the zentralverband der kassenrzte von gro - berlin [ association of panel doctors of greater berlin ] and other organisations of the medical profession , who mingled with the  great in medicine such as charcot and rudolf virchow ( 18211902 ) , ernst von bergmann ( 18361907 ) as well as robert koch ( 18431910 ) , and philosophers such as eduard von hartmann ( 18421906 ) , max dessoir and max scheler ( 18741928 ) , was treated by the nazis like all the other jewish doctors. in 1938 , moll lost his medical licence and was thereby banned from the medical profession . kristallnacht and the attack on poland and died lonely and impoverished on the same day as his great rival sigmund freud . access to the cemetery chapel was refused ; the priest in charge refused to speak at moll s grave . the scientific world , who had honoured him in 1932 with a festschrift , remained silent . there are even hints that towards the end of his life his catholic housekeeper had to hide him from the nazis . this housekeeper died , according to schultz , in 1944 in the concentration camp ravensbrck . 

  since the eulenburg trial libellous pamphlets , in which he was vilified as a pervert , especially as a disgusting boot - licker , had already circulated in the 1910s . the police kept secret dossiers on him , which were either full of denunciations or completely banal . 
  on 4 october 1920 , the media had already reported his death . 
  shortly after hitler had come to power , hirschfeld s institut fr sexualforschung [ institute for sex research ] in berlin was repeatedly harassed by the police and the sturmabteilung until it was ravaged and ransacked by nazi students on 6 may 1933 . four days later , books , among them hirschfeld s , were burnt in public and a bust of his was symbolically speared . in the nazi inflammatory pamphlets , hirschfeld was vilified , together with freud and other prominent jews . the caption under a photo of him , for example , read :  protector and promoter of pathological sexual aberrations , also in his physical appearance probably the most disgusting of all jewish monsters. 
  for the nazis , hirschfeld represented the perfect example of degeneration : racially , sexually , morally and politically . hirschfeld had still not returned to germany from a trip around the world , which he had started in november 1930 . via austria and switzerland he arrived in france in 1933 . in his letter to the german foreign secretary in early 1934 moll was outraged : [ t]hat the previous local doctor , mr dr magnus hirschfeld , tells in paris and also in lyon , that he was forced to leave germany because of the persecution of jews and also for political reasons  . according to my information magnus hirschfeld has left germany for completely different reasons , not because he is discriminated against as a jew , also not because he is a social democrat , but because rumour has it that there had been misconduct in a totally different direction . [ t]hat the previous local doctor , mr dr magnus hirschfeld , tells in paris and also in lyon , that he was forced to leave germany because of the persecution of jews and also for political reasons  . according to my information magnus hirschfeld has left germany for completely different reasons , not because he is discriminated against as a jew , also not because he is a social democrat , but because rumour has it that there had been misconduct in a totally different direction . magnus hirschfeld died on 14 may 1935 in exile , weakened by diabetes mellitus and malaria . he had tried again , unsuccessfully , to found an institute for sex research in france . albert moll , deeply identifying with the german fatherland and its culture , apparently could not allow himself to see clearly the situation that jews in nazi germany were in and what the situation of the jew hirschfeld was like in exile .
albert moll was one of the most influential sexologists during the first three decades of the twentieth century . 
 in contrast to his rivals sigmund freud and magnus hirschfeld , his achievements have not yet been recognised adequately . 
 the author gives a comparative account of the work of these three protagonists . 
 this shows that moll formed some ideas which are regarded as psychoanalytical today before freud , and that he , in contrast to hirschfeld , was able to reflect critically on contemporary discourses , such as the debates on racial improvement through eugenics . as scientific theories , 
 freud s psychoanalysis represented the unconscious , fantasy , experience and latency , while moll s sexology represented consciousness , ontological reality , behaviour and manifestation . 
 moll s major disagreement with hirschfeld s sexology was his advocacy of apolitical and impartial science , whereas hirschfeld s aim was to achieve sexual reforms politically . 
 added to these differences were strong personal animosities . 
 freud called moll a 
 beast and  pettifogger ; and moll complained about hirschfeld s  problematic character . 
 when hirschfeld escaped the nazi terror and went to paris , moll denounced him in order to prevent him rebuilding a new existence in exile .
