Vincent Drucci (born Ludovico D'Ambrosio; January 1, 1898 – April 4, 1927), also known as "The Schemer", was an American mobster during Chicago's Prohibition era who was a member of the North Side Gang, Al Capone's best known rivals. A friend of Dean O'Banion, Drucci succeeded him by becoming co-leader. He is the only American organized crime boss to have been killed by a policeman. Early years Drucci was born Ludovico D'Ambrosio in Chicago, Illinois, on January 1, 1898, to Italian parents from northern Italy. After serving in the U.S. Navy, he returned to Chicago and started committing small-time crimes such as breaking open pay telephone coin boxes. He joined Dean O'Banion's North Side Gang, which had taken over the formerly legal breweries and distilleries in that part of the city giving them massive profits from illicit production of alcohol, in addition to shakedowns and other rackets. Often described as mainly Irish-American, after O'Banion's death the North Side Gang was successively headed by Hymie Weiss, Drucci and Bugs Moran who were respectively of Polish, Italian and French descent, while the most influential members who never became leader were Louis Alterie, of Spanish parentage, Samuel Morton who was from a Jewish background, and the German Albert Kachellek. Though a leading member of the relatively small gang, Drucci acted as enforcer and was actively involved in numerous violent incidents; on one occasion when ambushed in the street by gunmen with a Capone trademark driveby, he charged at the assailants and tried to give chase in a hijacked car.

One female shop owner who refused to pay was beaten up by a husky woman as Drucci looked on. Drucci, whose practical jokes including making salacious comments to couples on the street while dressed as a priest, performed in a 1923 pornographic film called Bob's Hot Story. Drucci was believed to have been responsible for a November 30, 1926 incident at a Chicago North Side garage.
