Dennis Altman is a writer and academic who first came to attention with the publication of his book Homosexual: Oppression & Liberation in 1972.
This book, which has often been compared to Greer’s Female Eunuch and Singer’s Animal Liberation was the first serious analysis to emerge from the gay liberation movement, and was published in seven countries, with a readership which continues today.
Since then Altman has written twelve books, exploring sexuality, politics and their inter-relationship in Australia, the United States and now globally. These include The Homosexualization of America; AIDS and the New Puritanism; Rehearsals for Change, a novel (The Comfort of Men) and memoirs (Defying Gravity). His book, Global Sex (Chicago U.P, 2001), has been translated into five languages, including Spanish, Turkish and Korean. His most recent books are Unrequited Love  and God save the Queen
