Al Capone (a.k.a. 'Scarface'), one of the most famous American gangsters, rose to infamy as the leader of the Chicago mafia during the Prohibition era. Before being sent to Alcatraz Prison in 1931 from a tax evasion conviction, he had amassed a personal fortune estimated at $100 million dollars and was responsible for countless murders.
While prohibition was intended to decrease crime and violence it actually served to create the opposite. Gangsters like Al Capone took advantage of the basic economic principle of "supply and demand" and made hundreds of millions of dollars bootlegging alcohol in major cities along the east coast.
Alphonse Gabriel "Al" Capone,1/17/1899 – 1/25/1947, was an American gangster who led a Prohibition-era crime syndicate. The Chicago Outfit, which subsequently also became known as the "Capones", was dedicated to smuggling and bootlegging liquor, and other illegal activities such as prostitution, in Chicago from the early 1920s to 1931.
