Jack Nichols co-founded the Mattachine Societies of Washington DC in 1961 and of Florida in 1965. Nichols helped organize the first protest demonstration at The White House on April 17, 1965. He was among the first gay activists to challenge the American Psychiatric Association's position that homosexuality was a mental illness. In 1967, he appeared as a self-affirming gay male in an interview by Mike Wallace. That was CBS' first documentary on homosexuality.
From 1969 to 1973, Nichols and his partner, the late Lige Clarke, were the editors of GAY, America's first gay weekly newspaper from 1969-1973. Together they wrote the first non-fiction memoir by a male couple, I Have More Fun with You than Anybody. Nichols authored several books including Men's Liberation: A New Definition of Masculinity and The Gay Agenda: Talking Back to the Fundamentalists. Nichols' latest book is an account of his youthful indiscretions, The Tomcat Chronicles. Since 1997, he has edited the Internet news magazine, GayToday.com. He has been chronicled in 45 histories. Jack Nichols' biography appears in Dr. Vern Bullough's new history Before Stonewall: Activists for Gay and Lesbian Rights in Historical Context.
Jack Nichols passed away on May 2, 2005, in Florida at the age of 67.
