Rocky Marciano (born Rocco Francis Marchegiano; September 1 1923 – August 31 1969) was an American professional boxer and the World Heavyweight Champion from September 23 1952 to April 27 1956. Marciano is the only champion to hold the heavyweight title and go untied and undefeated throughout his career.
