Joe Frazier corners Muhammad Ali during their WBC/WBA World heavyweight title fight on March 8, 1971 at Madison Square Garden in New York City. Referred to as The Fight of the Century, as it was the first time that two undefeated boxers fought each other for the heavyweight title, Frazier won by unanimous decision. Relentless, swarming and implacable with that terrible, swift left hook, “Smokin’ Joe” reigned as the undisputed heavyweight champion from 1970 to 1973, and as an amateur won a gold medal at the 1964 Summer Olympics. Frazier was born on Jan. 12, 1944 and died of liver cancer on Nov. 7, 2011. (Neil Leifer)
