Lennox Claudius Lewis, CM, CBE (born September 2, 1965) is a retired boxer and the most recent Undisputed World Heavyweight Champion. He holds dual British and Canadian citizenship. As an amateur he won gold representing Canada at the 1988 Olympic Games after defeating future World Heavyweight Champion Riddick Bowe in the final.
Professionally, Lewis rose through the rankings and knocked out Donovan Ruddock to take over the number one position in the World Boxing Council (WBC) rankings and eventually be declared WBC heavyweight champion. He was the undisputed champion after defeating Evander Holyfield by unanimous decision in 1999. Throughout his professional career, Lewis suffered only two losses, both of which he avenged in rematches, both by knockout. Upon retirement in 2004, he had defeated every opponent he had faced.
Along with Muhammad Ali and Evander Holyfield, Lewis is one of only three boxers in history to have won the heavyweight championship three times (Some people might also count Vitali Klitschko and Michael Moorer as 'three time champs', as these two men have twice held recognised major world titles, in addition to a less regarded WBO title, thus technically making them 'three time champions').
