The two Ali versus Liston fights for boxing's world heavyweight championship were among the most anticipated, watched and controversial fights in the sport's history. At the time of the first Liston-Ali fight on February 25, 1964, Sonny Liston was the world heavyweight champion, having beaten Floyd Patterson by a first round knockout in September 1962. With an impressive knockout record to that point, Liston was a fighter many other heavyweights were reluctant to meet in the ring. Henry Cooper said that if Cassius Clay won, he was interested in a title fight, but if Liston won, he was not... going to get in the ring with him. Cooper's manager Jim Wicks said, "We don't even want to meet Liston walking down the same street." Liston was an ex-con with ties to organized crime whose ominous, glowering demeanor was so central to his image that Esquire Magazine caused a controversy by posing him in a Santa Claus hat for its December 1963 cover. Cassius Clay, on the other hand, was a glib, fast-talking 22-year-old challenger who enjoyed the spotlight.
