This is a timeline of asexual history worldwide. The briefness of this timeline can be attributed to the fact that acceptance of asexuality as a sexual orientation and field of scientific research is still relatively new.
1869: Karl-Maria Kertbeny, in the same pamphlets arguing against Prussian sodomy law where he coined the terms "homosexual" and "heterosexual", also used the word "monosexuals" to refer to people who only masturbate.
1890s
1896: German sexologist Magnus Hirschfeld wrote the pamphlet Sappho und Sokrates, which mentions people without any sexual desire and links them to the concept of "anesthesia sexual".
1897: German sexual reformist Emma Trosse gave the first definition of asexuality in her work Ein Weib? Psychologisch-biographische: Studie über eine Konträrsexuelle (A woman? Psychological-biographical study of a contrary-sexual) under the term Sinnlichkeitslosigkeit (Asensuality) and counted herself as such, stating "Verfasser hat den Mut, sich zu jener Kategorie zu bekennen (Author has the courage to admit to this category)."
20th century
1900s
1907: Reverend Carl Schlegel, a German immigrant living in New Orleans, was found guilty by the city Presbytery on charges of "homosexualism, Sodomy, or Uranism." Schlegel was quoted as advocating for "the same laws" for "homosexuals, heterosexuals, bisexuals asexuals."
1920s
1922: Jennie June, an American author on sexual and gender nonconformity, wrote "The Female Impersonators." In it, June describes people known as "anaphrodites," people who do not experience sexual attraction. Says June: "their minds are devoid of hero-worship and they shudder violently at the very thought of any kind of association grounded on sex differences. Their anaphroditism is either an after-effect of an illness in childhood or congenital." June also mentions that "Sir Isaac Newton and Immanuel Kant appear to have been anaphrodites."
1940s
1948: The Kinsey Scale included the category "X" for males who reported no socio-sexual contacts or reactions; according to the research, 1.5% of adult male subjects fell into this category.
1950s
1953: The Kinsey Scale included the category "X" for females who reported no socio-sexual contacts or reactions; according to the research, 19% of female interviewees fell into this category.
1960s
1969: Anton Szandor LaVey in his book The Satanic Bible referenced asexuals and asexuality, stating that "Satanism condones any type of sexual activity which properly satisfies your individual desires – be it heterosexual, homosexual, bisexual, or even asexual".
1970s
1972: Lisa Orlando, on behalf of the Asexual Caucus of the New York Radical Feminists, published The Asexual Manifesto, describing an asexual person as someone "relating sexually to no one" and asexuality a philosophy in which sex is rejected unless it is both "congruent with our values and totally incidental and unimportant to our relationships". The article further outlines particular harmful myths associated with the importance of sex in relationships, broadly aligned with the concepts of amatonormativity and compulsory sexuality.
1973: Activists at Barnard College were pictured to include "asexual" on a board advocating to "choose your own label" and had their picture featured in February/March 1973 edition of Off Our Backs. The picture was intended to be released in the previous article which described asexuality to be "an orientation that regards a partner as nonessential to sex, and sex as nonessential to a satisfying relationship."
1977: Myra Johnson wrote one of the first academic papers about asexuality as part of the book The Sexually Oppressed. She described "asexuality" as a complete lack of sexual desire, while those who do experience sexual desire but have no wish to satisfy it with others were labeled as "autoerotic". Johnson focused on the problems experiences by such women, who she felt were often ignored by the sexual revolution and feminist movements of the time.
1979: In a study published in Advances in the Study of Affect, Michael D. Storms reimagined the Kinsey Scale as a two-dimensional map which included asexuality, defined as exhibiting little to no homo-eroticism nor hetero-eroticism. This type of scale accounted for asexuality for the first time. Storms conjectured that many researchers following Kinsey's model could be mis-categorizing asexual subjects as bisexual, because both were simply defined by a lack of preference for gender in sexual partners.
1980s
1980: Publication of the DSM-III, which was the first version of the DSM to include a disorder relating to low sexual desire. This category was initially called Inhibited Sexual Desire (ISD) and later subdivided into Hypoactive Sexual Desire Disorder (HSDD) and Sexual Aversion Disorder (SAD) in the revision published in 1987 (DSM-III-R), the former relating to a lack of interest in sex and the latter a phobic avoidance.
1983: The first study that gave empirical data about asexuals was published in 1983 by Paula Nurius, concerning the relationship between sexual orientation and mental health. The study used a variant of Kinsey's model, and scored participants according to sexual behaviour and desire for it.
1989: American talk show host Sally Jesse Raphael interviewed Toby (alias of Jim Sinclair), a then self-described androgynous and nonsexual person.
1990s
1993: The book Boston Marriages: Romantic but Asexual Relationships Among Contemporary Lesbians by Esther D. Rothblum and Kathleen A. Brehony was released.
1997: Activist Jim Sinclair posted in their website the essay Personal Definitions of Sexuality, originally written in response to a class assignment in 1987, where they defined themself as asexual.
1997: Zoe O'Reilly published the article My life as an amoeba in the StarNet Dispatches webzine, a first-person exploration of asexuality that sparked responses through the late 90s and early 2000s by people who identified with it.
