Tom Waddell (born Thomas Flubacher; November 1, 1937 – July 11, 1987) was an American physician, decathlete who competed at the 1968 Summer Olympics, and founder of the Gay Olympics (later known as the Gay Games).
Adopted by former vaudeville acrobats, Waddell excelled in athletics and eventually attended medical school. He competed in the 1968 Summer Olympics, and after a career-ending injury, he started a successful medical practice in San Francisco. Inspired by his experience in a gay bowling league, Waddell founded the Gay Olympics, emphasizing sportsmanship, personal achievement, and inclusiveness. He also had a daughter with lesbian athlete Sara Lewinstein. Diagnosed with AIDS in 1985, Waddell died in 1987. His life and contributions to LGBTQ history have been posthumously honored in multiple ways.
