With a limited amateur background, former world heavyweight champion Big George Foreman won a gold medal at the 1968 Olympics in Mexico City.

He defeated Ionas Chepulis of the Soviet Union, stopping him in two rounds, and later walked around the ring carrying the American flag.

Foreman turned professional in June 1969. He defeated South American champion Gregorio Peralta 74-5-8 at Madison Square Garden to win his 28th fight.

In August 1970, he stopped iron chin Canadian George Chuvalo, 59-15-2, at Bagan. Prior to that, Chuvalo had only been stopped by 'Smokin' Joe Frazier and that was the only time in his career.

In January 1973, Foreman won the world heavyweight title by destroying Frazier 29-0 in two rounds in Kingston, Jamaica.

In September 1974, he stopped 30-2 Ken Norton in Caracas, Venezuela. In October, he lost his title 44-2 to former champion Muhammad Ali with a stop in Zaire, Africa.

Foreman returned in January 1976 in one of the biggest heavyweight fights ever, stopping 31-3-1 Ron Lyle for the NABF title in what Ring magazine called “Fight of the Year”. In June, in a rematch with Frazier, he stopped him in 5 rounds at the Nassau Coliseum, New York.

After four wins, Foreman was upset by Philly's Jimmy Young, 20-5-2, in San Juan, Puerto Rico. His entire life changed while in the dressing room when he saw a vision of Jesus that would eventually lead him to become a preacher.

In April 1991, Foreman won 26 consecutive fights before being defeated 25-0 by champion Evander 'The Real Deal' Holyfield in Atlantic City, New Jersey.

He then won three in a row before losing to Tommy 'The Duke' Morrison 35-1 in Las Vegas. In his next fight, he knocked out champion Michael 'Double M' Moorer 35-0 in Las Vegas to win the world title while trailing on all cards in ten rounds. At 45 he became the oldest boxer to win the title.

Foreman won a controversial majority decision over Germany's Axel Schulz, 21-1-1, in April 1995 in Las Vegas. Two fights and two years later, he defeated Lou Savarese 35-0 in Atlantic City. After refusing to grant Schulz a rematch, he was stripped of his title by winning the WBU title.

Later, in November 1997, in his last final fight, he lost a controversial majority decision to Shannon 'The Cannon' Briggs in Atlantic City and retired from boxing.

His final record was an impressive 76-5 with some 68 knockouts.
