Early Life & Family
Rocky Marciano was born Rocco Francis Marchegiano on September 1, 1923, in Brockton, Massachusetts, to Italian immigrant parents. He worked manual labor jobs as a young man and served in the U.S. Army during World War II before turning to boxing.
Rise to Fame
Marciano turned professional in 1947 and built an undefeated record through the following years, known for his relentless pressure and heavy punching power despite being shorter and having a shorter reach than many of his opponents. He won the world heavyweight title in 1952 by knocking out Jersey Joe Walcott.
Career History
Marciano defended his heavyweight title six times, defeating opponents including Ezzard Charles and Archie Moore, before retiring in 1956 with a perfect professional record of 49 wins and no losses, 43 of them by knockout. He remains the only heavyweight champion in history to retire undefeated.
How They Built Their Wealth
Marciano’s income came from boxing purses earned during his championship reign, along with paid personal appearances after his retirement. By the standards of boxing at the time, his purses were modest compared to those of later eras, and reports describe him as frugal, investing part of his earnings in real estate.
Personal Life
Marciano married Barbara Cousins in 1950, and the couple had two children. He was killed on August 31, 1969, one day before his 46th birthday, when the small private plane he was traveling in crashed near Newton, Iowa.
