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 a troubled childhood, Foreman took up boxing and was a gold medalist at the 1968 Olympics. He 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 unable to secure another title shot, and retired following a loss to Jimmy Young in 1977. Claiming to have had a religious epiphany, Foreman became an ordained Christian minister. Ten years later, he announced a comeback and, 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.
