Henry Valentine Miller (December 26, 1891 – June 7, 1980) was an American novelist. He broke with existing literary forms and developed a new type of semi-autobiographical novel that blended character study, social criticism, philosophical reflection, stream of consciousness, explicit language, sex, surrealist free association, and mysticism. His most characteristic works of this kind are Tropic of Cancer, Black Spring, Tropic of Capricorn, and the trilogy The Rosy Crucifixion, which are based on his experiences in New York and Paris (all of which were banned in the United States until 1961). He also wrote travel memoirs and literary criticism, and painted watercolors.
