Al Capone was one of the most famous American gangsters. Also known as "Scarface," Capone rose to infamy as the leader of the Chicago mafia during Prohibition. Before being sent to Alcatraz Prison in 1931 from a tax evasion conviction, he had amassed a personal fortune estimated at $100 million and was responsible for countless murders.
