Jan 17, 1942 to Jun 3, 2016
U.S.born Cassius Marcellus Clay Jr(January 17, 1942 – June 3, 2016) was an American professional boxer, activist, and philanthropist. He is nicknamed "The Greatest" and is widely regarded as one of the most significant and celebrated sports figures of the 20th century and as one of the greatest boxers of all time.
By late 1963, Clay had become the top contender for Sonny Liston's title. The fight was set for February 25, 1964, in Miami Beach. Liston was an intimidating personality, a dominating fighter with a criminal past and ties to the mob. Based on Clay's uninspired performance against Jones and Cooper in his previous two fights, and Liston's destruction of former heavyweight champion Floyd Patterson in two first-round knock outs, Clay was a 7–1 underdog.
In March 1966, Ali refused to be inducted into the armed forces. He was systematically denied a boxing license in every state and stripped of his passport. As a result, he did not fight from March 1967 to October 1970—from ages 25 to almost 29—as his case worked its way through the appeals process before his conviction was overturned in 1971.
Ali defended his title against former heavyweight champion Floyd Patterson on November 22, 1965. Before the match, Ali mocked Patterson, who was widely known to call him by his former name Cassius Clay, as an "Uncle Tom", calling him "The Rabbit". Ali won the fight in the 12th round through technical knockouts.
Ali and Frazier's first fight, held at the Garden on March 8, 1971, was nicknamed the "Fight of the Century", due to the tremendous excitement surrounding a bout between two undefeated fighters, each with a legitimate claim as heavyweight champions.
The defeat of Frazier set the stage for a title fight against heavyweight champion George Foreman in Kinshasa, Zaire, on October 30, 1974—a bout nicknamed The Rumble in the Jungle. Ali won by knockout in the 8th round.
Following this win, on July 27, 1979, Ali announced his retirement from boxing. His retirement was short-lived, however; Ali announced his comeback to face Larry Holmes for the WBC belt in an attempt to win the heavyweight championship an unprecedented fourth time. The fight was largely motivated by Ali's need for money.
