George Edward Foreman (nicknamed "Big George") (born January 10, 1949) is a retired American professional boxer, former two-time World Heavyweight Champion, Olympic gold medalist, ordained Baptist minister, author and entrepreneur. After dropping out of school at the age of fifteen, later training in California as a boxer for a couple of years, he went on to be a gold medalist at the 1968 Olympics. Foreman won the World Heavyweight title with a second round knockout of then-undefeated Joe Frazier in Kingston, Jamaica in 1973. He made two successful title defenses before losing to Muhammad Ali in "The Rumble in the Jungle" in 1974. He was able to secure another title shot, but retired following a loss to Jimmy Young in 1977. He has said he was reborn following that fight, and subsequently became a practicing minister in the Houston area. Ten years later, Foreman announced a comeback. In November 1994, at age 45, he regained the Heavyweight Championship by knocking out Michael Moorer. He remains the oldest Heavyweight Champion in history. He retired in 1997 at the age of 48, with a final record of 76–5, including 68 knockouts.
