Otto Rank (1884-1939) served as Freud's closest partner in the psychoanalytic movement from 1906 to 1926. From 1923 on, Rank, initially with Ferenczi, focused on making analysis more therapeutic, emphasizing current experience in the session over historical exploration and interpretation. Rank settled on will as a missing factor, and wrote extensively about it after the break with Freud in 1926, when he moved to Paris. He emphasized the here-and-now, redefined “resistance” as a positive aspect of counter-will, and suggested a time limit for analysis. Ousted from analytic circles in 1930, he eventually moved to New York, continuing to treat patients and teach until his unexpected death at 55 in 1939. After decades of obscurity, Rank has gained readers and therapists whose orientation is interpersonal, client-centered, relational, humanistic, or existential. His influence on post-Freudian ego-psychology is finally being acknowledged as are his ideas about creativity, will, life-fear and death-fear, guilt, and ethics.
