Baraka also worked as editor and critic for the literary and arts journal "Kulchur" (1960–65). With Diane di Prima he edited the first twenty-five issues (1961–63) of their small magazine "The Floating Bear". In October 1961, the U.S. Postal Service seized "The Floating Bear #9"; the FBI charged them for obscenity over William Burroughs' piece "Roosevelt after the Inauguration". In the autumn of 1961 he co-founded the New York Poets Theatre with di Prima, the choreographers Fred Herko and James Waring, and the actor Alan S. Marlowe. He had an extramarital affair with di Prima for several years; their daughter, Dominique di Prima, was born in June 1962.
