Mark Jacobson is a writer and journalist based in Brooklyn, New York. He is known for his explorations of the seamy side of urban life, both here and abroad, and for his offbeat and witty take on popular culture. Mark is a Contributing Editor at New York Magazine and a frequent contributor to The Village Voice, National Geographic, Natural History Magazine, Men's Journal, and other publications.

Mark has written several articles on gangs. In 2000, he published a profile of Frank Lucas, "once the city's biggest, baddest heroin kingpin"; this formed the basis for the new Ridley Scott film, "American Gangster", starring Denzel Washington and Russell Crowe.
