Dr. John Fryer, a Philadelphia psychiatrist credited with declassifying homosexuality as an illness, died Saturday at age 65. In 1972, Fryer appeared on a panel at the American Psychiatric Assn. in disguise announcing: "I am a homosexual. I am a psychiatrist. I am a member of the APA. I could be any one of more than 100 gay psychiatrists at this convention." In 1973, the APA declassified homosexuality as an illness.
