In 1972, Kameny and Barbara Gittings convinced the American Psychiatric Association (APA) to hold a debate, "Psychiatry: Friend or Foe to the Homosexual?; A Dialogue" at their annual meeting in Dallas. It was for this debate that Dr. John E. Fryer, a gay psychiatrist in disguise as "Dr. Henry Anonymous", testified as to how homosexuality being listed as a mental disease in the APA's "Diagnostic and Statistical Manual of Mental Disorders" (DSM) affected the lives of gay psychiatrists and other homosexuals. Kameny had approached numerous gay psychiatrists, but Fryer was the only one who agreed to testify, and even he would only do so in disguise for fear of losing his position at Temple University, where he did not have tenure. The following year, the APA removed homosexuality from the DSM. Kameny described that day - December 15, 1973 - as the day "we were cured en masse by the psychiatrists."
