Herbert Asbury (September 1, 1889 – February 24, 1963) was an American journalist and writer who is best known for his true crime books detailing crime during the 19th and early 20th century such as Gem of the Prairie: An Informal History of the Chicago Underworld, The Barbary Coast: An Informal History of the San Francisco Underworld and The Gangs of New York. The Gangs of New York was later adapted for film as Martin Scorsese's Gangs of New York (2002). However, the film adaptation of Gangs of New York was so loose that Gangs was nominated for "Best Original Screenplay" rather than as a screenplay adapted from another work.In earlier decades, Asbury was known for his self-described "informal histories", which included descriptions of various cities, focusing on violence, crime, prostitution and lurid events.
