During his amateur career the young Cassius Clay registered 100 wins and five losses, competed in the famous Golden Gloves tournament, and finally as an amateur in the 1960 Olympic games before turning pro. The opponent of his first professional fight remembers him as being lightening fast, and delivering the hardest body blow he'd ever taken. His first title fight was against Sonny Liston, on Feb 25th, 1964 in Miami Beach. Clay won, becoming the heavyweight champion of the world. In March of '64 he celebrated his joining the Fellowship of Islam by changing his name to Muhammad Ali. In 1966 Ali became a conscientious objector to the war in Vietnam, refusing to fight due to his religious beliefs, and took his personal battle to court. Toward the end of the '70's, Ali was firmly established as a cultural phenomenon, his views on politics, fate, society and life sought by the media and public. It's hard to think of another athlete that so many have looked to, in such a way. Ali retired in June, 1979. He was examined at the Mayo Clinic and diagnosed with Parkinson's disease in 1983. Since retiring he has worked endlessly for various humanitarian causes, including the search for a cure for Parkinson's sufferers.
