Duncan Campbell (born 1955 or 1956), sometimes known as "the Quadfather", is a Canadian co-inventor of murderball. In the 1970s, Campbell invented the sport with four other Canadians before the sport was renamed to wheelchair rugby. In the sport, Campbell coached the Canadian team that went to the 2000 Summer Paralympics and organized the 2010 IWRF World Championship. Apart from wheelchair rugby, Campbell became a recreational therapist for the G. F. Strong Centre in 1986. His honours include an induction into the Canadian Paralympic Committee Hall of Fame in 2005 and receiving the Paralympic Order in 2013.
