33. Frank J. Wilson was the man who brought down Al Capone
Although Eliot Ness and the Untouchables got the credit for ending Al Capone’s reign as the king of organized crime in Chicago, it was really Frank J. Wilson, an agent of the Treasury Department, who lead the tax evasion investigations which led to Ralph and Al Capone being charged with federal income tax evasion. Wilson’s work led to Al Capone being indicted on more than twenty charges of not paying taxes on over a quarter of a million dollars of income, and he was convicted and sentenced to eleven years in prison. Wilson later participated in the investigation following the Lindbergh kidnaping, and served as the head of the Secret Service under FDR and Harry Truman.
