Otto Rank was an Austrian psychoanalyst, writer, and philosopher. Born in Vienna, he was one of Sigmund Freud's closest colleagues for 20 years, a prolific writer on psychoanalytic themes, editor of the two leading analytic journals of the era, managing director of Freud's publishing house, and a creative theorist and therapist. In 1926, Rank left Vienna for Paris and, for the remainder of his life, led a successful career as a lecturer, writer, and therapist in France and the United States.

Henry Valentine Miller was an American novelist, short story writer and essayist. 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 City and Paris. He also wrote travel memoirs and literary criticism, and painted watercolors.
