Muhammad Ali standing over Sonny Liston after the first-round knockdown in their heavyweight title rematch, Lewiston, Maine. Ali had won his first heavyweight title against Liston in February 1964 while still fighting as Cassius Clay, but soon afterward converted to Islam and adopted the name Muhammad Ali, rejecting his former name as a "slave name."
