Stephen A. Mitchell (1946-2000) was a leader in the field of modern psychoanalysis. An adjunct professor and clinical supervisor at New York University's postdoctoral program in psychotherapy and psychoanalysis, Mitchell's emphasis on the relational perspective shaped the way that American psychoanalysts practice their profession. He was the founding editor of the journal Psychoanalytic Dialogues and the author of several influential books, including Object Relations in Psychoanalytic Theory and Hope and Dread in Psychoanalysis.
