1970 - Joe Frazier knocked out Jimmy Ellis in the second round of their New York fight and became the world heavyweight boxing champion.  

Joseph William "Joe" Frazier, known as Smokin' Joe, born January 12, 1944, is a former Olympic and World Heavyweight boxing champion, whose professional career lasted from 1965 to 1976, with a brief comeback in 1981.

Frazier emerged as a contender in the mid-1960s, defeating Jerry Quarry, Oscar Bonavena, Buster Mathis, Eddie Machen, Doug Jones and Jimmy Ellis en route to becoming undisputed heavyweight champion in 1970, and followed up by defeating Muhammad Ali in the highly-anticipated "Fight of the Century" in 1971. Two years later Frazier lost his title when he was knocked out by George Foreman. He launched a comeback, beating Joe Bugner, losing a rematch to Ali, and beating Quarry and Ellis again.

Frazier's last world title challenge came in 1975, but he was beaten by Ali in their brutal rubbermatch. He retired in 1976 following a second loss to Foreman. He made a comeback in 1981, fighting just once, before retiring for good.
