Thirteen trustees of the American Psychiatric Association sat around a table. They voted, one by one. The tally was thirteen to zero. On December 15, 1973, the APA’s board approved a resolution removing homosexuality from the second edition of its Diagnostic and Statistical Manual of Mental Disorders. The action reclassified homosexuality as a ‘sexual orientation disturbance’ only for those distressed by it, effectively de-pathologizing same-sex attraction for the vast majority. The decision was ratified by a 58% majority of the APA’s full membership in April 1974, but not without fierce opposition from a significant psychoanalytic minority.
The vote was not a sudden medical enlightenment but the culmination of sustained activist pressure. Psychiatrist and gay activist Dr. John E. Fryer, disguised in a mask and using the pseudonym ‘Dr. Henry Anonymous,’ had addressed the APA’s annual meeting in 1972, describing the professional and personal toll of stigma. Groups like the Gay Liberation Front and the Gay Activists Alliance had been protesting APA conventions since 1970, heckling speakers and demanding a seat at the table. Scientific data, like Alfred Kinsey’s surveys and Evelyn Hooker’s 1957 study showing no psychological difference between homosexual and heterosexual men, provided the intellectual ammunition, but activism forced the institution to load the gun.
This event mattered because it transferred a condition from the realm of medicine to the realm of identity. By stripping the official label of illness, the APA removed the primary justification for discrimination in employment, child custody, immigration, and licensing. It undermined the legal basis for police entrapment and the medical rationale for coercive ‘treatments’ like aversion therapy. The vote did not end prejudice, but it disarmed a central, authoritative argument of the prejudiced.
The impact was both immediate and slow-burning. Some psychiatrists resigned from the APA in protest; conservative groups cited the ‘sickness’ model for decades. Yet the decision created a domino effect. Major health and professional organizations followed suit. It provided a legal foundation for subsequent civil rights arguments. The APA’s vote did not grant rights, but it revoked a diagnosis, transforming a medical ‘fact’ into a civil disagreement. That shift was the prerequisite for every political battle that followed.
