Alphonse Gabriel "Al" Capone (January 17, 1899 – January 25, 1947) was an Chicago gangster who led the Chicago Mob. The Chicago Outfit, which subsequently also became known as the "Capones," smuggled liquor, and other illegal activities such as prostitution, in Chicago from the 1920's and 1930's.
Capone became a highly visible public figure. He made donations to various charitable endeavors using the money he made from his activities, and was viewed by many to be a "modern-day Robin Hood". Capone's public reputation was damaged in the wake of his supposed involvement in the 1929 Saint Valentine's Day Massacre, when seven rival gang members were executed.
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.
