Gerald Chapman (August, 1887 – April 6, 1926), known as "The Count of Gramercy Park", "The Gentleman Bandit", and "Gentleman Gerald", was an American criminal who helped lead an early Prohibition-era gang from 1919 until the mid-1920s. His nicknames came from his ability to pose as a member of the wealthy elite, which allowed him to fool potential victims and avoid scrutiny from investigators. Chapman was the first criminal to be dubbed "Public Enemy Number One" by the press.
