George Kelly Barnes, better known by his nickname Machine Gun Kelly, was an American gangster from Memphis, Tennessee, active during the Prohibition era. His nickname came from his favorite weapon, a Thompson submachine gun. He is best known for the kidnapping of oil tycoon and businessman Charles F. Urschel in July 1933, from which he and his gang collected a $200,000 ransom. Urschel had collected and left considerable evidence that assisted the subsequent investigation by the Federal Bureau of Investigation (FBI), which eventually led to Kelly's arrest in Memphis on September 26, 1933. His crimes also included bootlegging and armed robbery.
