Cassius Marcellus Clay Jr. was born in 1942 in Louisville, Kentucky. He took up boxing after a stolen bicycle led him to coach Joe Martin. Winning light-heavyweight gold at the 1960 Rome Olympics, he turned professional with flamboyant predictions and footwork that defied heavyweight norms. In 1964 he upset Sonny Liston to claim the world title and announced his conversion to Islam, adopting the name Muhammad Ali.
Ali refused induction into the U.S. Army during the Vietnam War, citing religious objection and racial injustice. Stripped of his title and facing prison, he spoke on college campuses while legally fighting the conviction, which the Supreme Court overturned in 1971. He regained the championship in epic bouts—the 'Rumble in the Jungle' against George Foreman in Zaire and the 'Thrilla in Manila' against Joe Frazier.
Parkinson's syndrome, likely linked to ring trauma, slowed his speech in later decades, yet Ali remained a global ambassador, lighting the 1996 Atlanta Olympics cauldron. He died in 2016 in Scottsdale, Arizona, mourned as a champion who placed conscience alongside athletic genius.
