Tony DeMarco (January 14, 1932 – October 11, 2021), born Leonardo Liotta,[1] was an American boxer and World Welterweight Champion.
[2] Born to Sicilian immigrants from Sciacca (AG), Vincent and Giacomina, DeMarco grew up in the North End neighborhood of Boston.
DeMarco was also, for a short time, a resident of Phoenix, Arizona,[3] where he was a business owner and where he suffered the death of his young son by way of a car-bicycle collision.
Due to the minimum age of eighteen, in order to box professionally, Liotta used the baptismal certificate of Tony DeMarco so that he could compete.
DeMarco was also featured in "The Flame and Fury of Fleet Street," a segment of the documentary, Boston's North End: An Italian American Story.
