Al Capone, also known as "Scarface," was a notorious American gangster who led the Chicago Outfit during the Prohibition era, becoming one of the most infamous criminals of the 20th century. His criminal empire was involved in bootlegging, gambling, and various illicit activities, amassing immense wealth and power. Despite his criminal background, Capone opened one of the first soup kitchens in Chicago during the Great Depression, serving thousands of meals to the unemployed and hungry, which helped improve his public image. In 1931, Capone was convicted of tax evasion and sentenced to 11 years in prison, serving time at Alcatraz before being released in 1939 due to deteriorating health.
