Lennox Claudius Lewis (born 2 September 1965) is a boxing commentator and former professional boxer who competed in the heavyweight division from 1989 to 2003. He was a three-time world champion, a two-time lineal champion, and held the undisputed championship. Holding dual British and Canadian citizenship, Lewis represented Canada as an amateur at the 1984 and 1988 Olympics, winning the super-heavyweight gold medal in 1988. Lewis is regarded by many as one of the greatest heavyweight boxers of all time, and is considered among the greatest British boxers and among the greatest Canadian boxers in history.
In his first three years as a professional, Lewis won several regional heavyweight championships, including the European, British, and Commonwealth titles. After winning his first 21 fights, he defeated Donovan Ruddock in 1992 to take over the number one position in the World Boxing Council (WBC) rankings. He was declared WBC heavyweight champion later that year after Riddick Bowe gave up the title, refusing to defend it against Lewis. He defended the title three times before an upset knockout loss to Oliver McCall in 1994. Lewis avenged the loss in a 1997 rematch to regain the vacant WBC title.
