Katz appears in San Francisco to discuss his recently published book, Gay American History. Readings from Katz's book by the host are interspersed with clips of Katz's speech in SF. Katz lectures on a diverse number of topics, including gays and the Communist witch hunt; the history and psychiatric/corrective treatments to homosexuality; Lucy Ann Lobdell and lesbian feminism; gay Native Americans; Harry Hay and the founding of the Mattachine Society; medical studies of homosexuality from late 18th century to World War II; and Almada Sperry's correspondence with Emma Goldman. The show concludes with a reading from "Coming Out", a play written by Katz.
