After turning professional in 1960, he compiled a record of 19-0 with 15 knockouts before defeating Sonny Liston for the world heavyweight championship in 1964. He changed his name after joining the Nation of Islam and forfeited his title after refusing to be drafted into the military during the Vietnam War. He regained the heavyweight title twice more during his career and remains the only three-time lineal champion of the heavyweight division. In 1999, The Associated Press voted him “Sportsman of the Century.” Along with world-renowned boxing promoter Don King, Ali helped bring iconic fights like “The Rumble in the Jungle” (1974) and “The Thrilla in Manila” (1975) to a global audience. In 1996, he was diagnosed with Parkinson’s disease, which slowly robbed him of his physical abilities and public appearances.

Turning professional shortly afterward, he compiled a string of knockout wins that culminated in a second-round knockout of then-undefeated boxing icon Muhammad Ali in 1974, which earned him the lineal and undisputed heavyweight titles. He lost these titles in 1980 to Ali in their highly publicized “Rumble in the Jungle” fight. After two more losses against Larry Holmes and Trevor Berbick, Foreman retired from boxing for 10 years and worked as a commentator for HBO’s boxing coverage.

In 1984, he made a comeback and regained the heavyweight title by defeating Pinklon Thomas via unanimous decision. He then lost these titles against Evander Holyfield by KO in 1991.
