Robert Edward Duncan (January 7, 1919 in Oakland, California– February 3, 1988) was an American poet and a devotee of H.D. and the Western esoteric tradition who spent most of his career in and around San Francisco. Though associated with any number of literary traditions and schools, Duncan is often identified with the poets of the New American Poetry and Black Mountain College. Duncan saw his work as emerging especially from the tradition of Pound, Williams and Lawrence. Duncan was a key figure in the San Francisco Renaissance.
