John Hoffman's career as a bona fide fringe writer began with the publication of his cult classic, The Art and Science of Dumpster Diving. His previous employment is equally checkered - he has worked as a psychiatric counselor, printer's assistant, security guard, pizza cook, soldier, activist, newspaper reporter, hotel clerk, apartment manager and city councilman. He is now studying for a law degree.
