John Herbert Dillinger (June 22, 1903 - July 22, 1934) was an American gangster in the Depression-era United States accused of robbing 24 banks and four police stations. In the heyday of the Depression-era outlaw Dillinger was the most notorious of all. He courted publicity, styling himself as a Robin Hood figure, and the media of his time ran accounts of his bravado and colorful personality. In response, the Director of the Bureau of Investigation, J. Edgar Hoover, developed a more sophisticated Federal Bureau of Investigation as a weapon against organized crime. After evading police in four states for almost a year, Dillinger was wounded and returned to his father's home to recover. On July 22, 1934 the police and Division of Investigation closed in on the Biograph Theater. Federal agents, led by Melvin Purvis and Samuel P. Cowley, moved to arrest Dillinger as he exited the theater. He pulled a weapon and attempted to flee but was shot four times and killed. He was 31 years old.
