Sean Stephane Martin (December 29, 1950 – August 3, 2020) was an American-Canadian cartoonist, illustrator, and graphic designer, best known for creating the long-running Doc and Raider comic strip which appeared in LGBT publications in the 1980s and 1990s, and online in the 2000 and 2010s. Early life Martin was adopted as a child. His adoptive mother, Elsie Martin, who died in 2017, estimated his birth date as 29 December 1960 based on the date he was taken from a Catholic-run orphanage in Montreal. She also believed that he was born in Canada. He was raised in Texas, and lived in New York City and San Francisco before moving to Canada in 1986 and gaining Canadian citizenship in 1989. Career Martin produced the first Doc and Raider strips for a Vancouver gay publication in 1987. The titular characters' namesakes come from western novels written by J.D. Hardin Although the issue featuring Doc and Raider turned out to be the final issue of that publication, the strip was quickly picked up by other LGBT publications, including the Xtra! newspapers in Canada. Martin's fee for the strip was turned over to charities and organizations, going to causes that included AIDS hospices in New Zealand, and an arts festival in Scotland, with total donations estimated to be close to a quarter million dollars (US) (Exact figures are unknown because of variances in the number of currencies and irregularity of reporting involved, but it is a reliable estimate). The characters have also been used to promote safer-sex practices and AIDS education, as well as rodeos, country dance conventions, and film festivals. His works have often alluded to other queer comics artists of the past such as Tom of Finland by dressing up his characters as authority figures and highlighting their sexuality. He has also written about domestic relationships, as can be seen in Gay Comix #16, through the bickering between Doc and Raider. Martin was an avid lover of cats and they often were woven into his narratives. He published two books collecting strips: Doc and Raider: Caught on Tape (1994) and Doc and Raider: Incredibly Lifelike (1996). He retired the regular strip in 1997, but drew two five-page stories for the Little Sister's Defence Fund anthologies What's Right and What's Wrong in 2002. The strip's archive is housed at the National Archives of Canada and the Pride Archives at the University of Western
