Precursors The phenomenon of wearing clothing typical of the other sex was referred to in the
Hebrew Bible.
Karl Heinrich Ulrichs was a German lawyer and pioneer of sexology and gay rights. In 1862, he came out to friends and family that he was gay, coining the German term to describe himself (English:
Uranian). Ulrichs coined various terms to describe different sexual orientations, including Urning for a man who desires men (English "Uranian"), and Dioning for one who desires women. Ulrichs published urning pamphlets under his own name as an apologist for the cause, and is thus unique at that time and for some time thereafter. In 1868, the Austrian writer
Karl-Maria Kertbeny coined the word
homosexual in a letter to Ulrichs, and from the 1870s the subject of
sexual orientation (in modern terms) began to be widely discussed.
Karl Westphal quoted Ulrichs's writings in the first psychiatric paper on 'contrary sexual feeling' and largely used Ulrichs's theoretical framework. Ulrichs also corresponded for many years with psychiatrist Richard von Krafft-Ebing, who later acknowledged his debt to Ulrichs, stating that it was "only the knowledge of your books which motivated me to study this highly important area".
Richard von Krafft-Ebing was a German psychiatrist and author of the foundational work
Psychopathia Sexualis (1886). Krafft-Ebing had particular significance for the scientific study of homosexuality.
Karl Heinrich Ulrichs' theory of the "Urning" (Uranian) as a third sex greatly influenced Krafft-Ebing's thinking on the subject. Being part of the homosexual movement of Weimar Germany in the beginning, a first transvestite movement of its own started to form since the mid-1920s, resulting in founding first organizations and the first transvestite magazine,
Das 3. Geschlecht (''''). The rise of
National Socialism stopped this movement from 1933 onwards.
Magnus Hirschfeld Hirschfeld believed that clothing was only an outward symbol chosen on the basis of various internal psychological situations. Hirschfeld also clearly distinguished between transvestism as an expression of a person's "contra-sexual" (transgender) feelings and
fetishistic behavior, even if the latter involved wearing clothes of the other sex. Aware of Hirschfeld's studies of transvestism but disagreeing with his terminology, in 1913 Ellis proposed the term
sexo-aesthetic inversion to describe the phenomenon. In 1920 he coined the term
eonism, which he derived from the name of a historical figure, the
Chevalier d'Éon. Writing to sexologist
Norman Haire in 1925 while writing his book on
Eonism, Ellis wrote:
John Money coined
gender role in 1955, and
Robert J. Stoller introduced
gender identity in 1964. During this period, the term
transvestism was generally used in medical contexts to describe a disorder and not merely a behavior, and was considered deviant behavior found predominantly among homosexuals. was an American
transgender woman and
transgender activist. She published
Transvestia magazine from 1960 to 1980, and founded
Tri-Ess for male heterosexual cross-dressers. Prince has been considered a major pioneer of the transgender community. By the early 1970s, Prince and her approaches to crossdressing and transvestism were starting to gain criticism from transvestites and transsexuals, as well as sections of the gay and women's movements of the time. Controversy and criticism has arisen based on Prince's support for conventional societal norms, such as marriage and the traditional family model, as well as the portrayal of traditional gender stereotypes. Her attempts to exclude transsexuals, homosexuals, or fetishists from her normalization efforts of the practice of transvestism have also drawn much criticism. Prior to arriving in the United States in 1914, Benjamin studied at Hirschfeld's
Institut für Sexualwissenschaft in Berlin. From about this time onward he began to encounter and treat patients who he would later describe as transsexuals. In the 1930s he studied in Austria with
Eugen Steinach. Benjamin was asked by
Alfred Kinsey, a fellow sexologist, to see a young patient who was anatomically male but insisted on being female. Kinsey had encountered the child as a result of his interviews for
Sexual Behavior in the Human Male, which was published that year. This case rapidly caused Benjamin's interest in what he would come to call transsexualism realizing that there was a different condition to that of transvestism, under which adults who had such needs had been classified to that time. ==As a disorder==
