Lennox Claudius Lewis, CM, CBE (born 2 September 1965) is a former professional boxer who competed from 1989 to 2003. He is a three-time world heavyweight champion, a two-time lineal champion, and remains the last heavyweight to hold the undisputed title. Holding dual British and Canadian citizenship, Lewis represented Canada as an amateur at the 1988 Summer Olympics, winning a gold medal in the super-heavyweight division after defeating future world champion Riddick Bowe in the final.
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 WBC rankings. He was declared WBC heavyweight champion later that year after Riddick Bowe gave up the title to avoid defending 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 win back the vacant WBC title.
