Rocco Francis Marchegiano grew up in Brockton, Massachusetts, and turned to boxing after Army service in World War II. A relentless puncher, he drew national attention in 1951 by knocking out an aging Joe Louis. He became champion in 1952, winning the heavyweight title with a dramatic come-from-behind knockout of Jersey Joe Walcott.

Rocco Marchegiano was born in Brockton, Massachusetts, in 1923 to Italian immigrant parents. After serving in the Army during World War II, he took up boxing seriously and turned professional in 1947. Shortened to 'Rocky Marciano,' his name soon became feared in the heavyweight ranks.

Marciano's relentless pressure and devastating right hand, nicknamed the 'Suzie Q,' overwhelmed opponents. He knocked out Joe Louis in 1951 and won the title from Jersey Joe Walcott in 1952. Over four years as champion he turned back every challenger, including Ezzard Charles and Archie Moore.
Marciano retired in 1956 with a flawless 49-0 record, 43 of those wins by knockout, the only heavyweight champion ever to go out unbeaten. He was inducted into boxing's Hall of Fame in 1959. He died in a plane crash near Newton, Iowa, in 1969 at age 45.
