Sexual Anomalies and Perversions  

"I was in my early twenties when I first came upon Dr Magnus Hirschfeld’s Sexual Anomalies and Perversions, subtitled ‘A textbook for students, psychologists, criminologists, probation officers, judges, educationalists and all adults . This impressive description was obviously an attempt to forestall a prosecution for pornography - the book was usually to be seen in the windows of shops that sold rupture trusses, sex aids and encyclopedias of sexual behaviour. In those days before the permissive society, such works would never have been found in respectable bookshops."--The Misfits: A Study of Sexual Outsiders (1988) by Colin Wilson

“One of the first pioneers in the systematic investigation of sexual aberrations was Dr. Kahn, a Ruthenian physician who, though living in straitened circumstances, with few opportunities for research, nevertheless enriched the science of sexual pathology by many important discoveries. Another pioneer who deserves recognition was August Forel, who in his monumental work analyzed sexual aberrations with the same objectivity and attention to detail that he applied to his work on ants. Krafft-Ebing's Psychopathia Sexualis is still an inexhaustible storehouse of cases, to which modern investigators return again and again, in spite of the immense amount of more recent material. Havelock Ellis in his classic work dealt with the physiological determination of sadomasochistic phenomena, while Moll, Schrenk-Notzing, Fere, and Bloch, the great sexual physiologists of the late nineteenth century, were already able to lay the foundations of a general theory of the sexual sciences."--Sexual Anomalies and Perversions (1938) by Norman Haire
