Alphonse Gabriel “Al” Capone 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.
Capone was convicted on federal charges of tax evasion in 1931 and sentenced to federal prison; he was released on parole in 1939. His incarceration included a term at the then-new Alcatraz federal prison. In the final years of Capone’s life, he suffered mental and physical deterioration due to late-stage neurosyphilis, which he had contracted in his youth. On January 25, 1947, he died from cardiac arrest after suffering a stroke.
