Paul Castellano
Costantino Paul "Big Paul" Castellano (pronounced cas-TAY-llah-noh) (June 26, 1915 – December 16, 1985), also known as "The Howard Hughes of the Mob" and "Big Paulie" (or "PC" to his family), succeeded Carlo Gambino as head of the Gambino crime family, the nation's largest Cosa Nostra family at the time. The unsanctioned assassination of Castellano by John Gotti would spark years of animosity between the Gambinos and the other New York crime families. His nephew was actor Richard S. Castellano from The Godfather.
