On June 22, 1937, Louis knocked out James J. Braddock in the eighth round to become world heavyweight champion at age 23. A year later, his first-round demolition of German Max Schmeling in their 1938 rematch made him a national hero and a symbol of American defiance against Nazism.

Born in a sharecropper's cabin near Lafayette, Alabama, Louis moved with his family to Detroit. He took up boxing as a teenager and rose quickly through the amateur ranks before turning professional in 1934.

His 1938 rematch with Max Schmeling carried enormous political weight as war loomed in Europe. Louis ended it in just over two minutes, becoming a hero to Americans of all backgrounds and a powerful symbol against fascism.
Louis dominated the heavyweight division like no one before him, defending his title a record 25 times. He retired as champion in 1949 and remains one of the most influential and admired boxers in history.
