Henry Cooper was a famous name in the 60s in which sport?

Heavyweight boxer Sir Henry Cooper's fight against Cassius Clay (Muhammad Ali) in 1963 was one of the greatest events in British boxing history. Cooper was defeated but the match was very close, only ending when a cut opened up on Cooper's forehead. Cooper was left-handed and had a strong left hook. His long and successful career began when he was a teenager, competing in the 1952 Helsinki Olympics. In 1970, he was the British, European, and Commonwealth heavyweight champion. Incredibly popular in Britain, Cooper was the first person to win the BBC Sports Personality of the Year twice, in 1967 and 1970.
