Frank Capone (January 1895 – April 1, 1924) was a Chicago mobster who participated in the attempted takeover of Cicero, Illinois by his brother Al Capone's criminal organization.
Born Salvatore Capone, Frank was the son of Gabriele Capone, an Italian immigrant who settled with his wife Teresina in New York City in 1894. Besides Al, Frank had another brother who became a mobster, Ralph Capone. Growing up in New York, both Frank and Al became involved in the infamous Five Points Gang with mobster John Torrio. By 1918, Torrio had moved to Chicago to help a relative defend his rackets, and Torrio soon asked Al and later Frank to join him there.
By 1920, Torrio had taken charge of the South Side Gang and the Prohibition era had started. As the gang increased in power and wealth, so did Al and Frank. Although Al was prone to violence, Frank was reportedly considered much worse. Whereas Al usually wanted to negotiate, Frank opted to use violence immediately, explaining that, "You never get no back talk from a corpse.
In 1923, Chicago voters elected a new mayor, William Dever, who proceeded to crack down on Torrio, the Capone brothers, and their South Side Gang.
