Muhammad Ali (born Cassius Marcellus Clay, Jr.; January 17, 1942) is an American former boxer and three-time World Heavyweight Champion. As an amateur, he won a gold medal in the light heavyweight division at the 1960 Summer Olympics in Rome. After turning professional, he went on to become the first and only boxer to win the lineal heavyweight championship three times.
The two Ali versus Liston fights for boxing’s world heavyweight championship were among the most anticipated, watched and controversial fights in the sport’s history. Sports Illustrated magazine named the first Clay–Liston fight (Ali had not yet changed his name from Cassius Clay) as the fourth greatest sports moment of the twentieth century.
The first bout was held in February 1964 at Miami Beach, Florida, and the second in May 1965 in Lewiston, Maine.
