Ralph Greenson

In 1968 Ralph Greenson offered a developmental theory for homosexuality, which focuses on the need of boys to "dis-identify" from their mothers:

Greenson was named a clinical professor of psychiatry at the UCLA School of Medicine and served on the Board on Professional Standards and the Committee on Institutes in The American. He published fifty-three papers in psychoanalytic journals. The Technique and Practice of Psychoanalysis, published in 1967, has been described as "a thorough, highly technical textbook, with an instructive treatment of the working alliance," and stands "among the classic writings ... relating to the technique of psychoanalysis." In it "Greenson says that it's important for the patient to distinguish between his transference relations to the analyst and his realistic perceptions of him ... 'the non-transference relationship'" – views criticized however by Charles Brenner as "what Brenner calls resistive myths – myths that analysts who are unable to tolerate analytic abstinence have invented to justify their lapses from neutrality."

He published psychoanalytic material often dealing with analyzability, beginning of analysis, interpretations, dreams, working through, acting out, countertransference, and termination. His article On Gambling drew on his own "observations on gambling in the U. S. Army from 1942 to 1946, primarily among officers." In retrospect, "Greenson's essay is interesting because, unlike many other analysts, he considers cultural and historical material to be relevant, while accepting the overriding importance of the Oedipal conflict."

Ralph R. Greenson (born Romeo Samuel Greenschpoon, September 20, 1911 – November 24, 1979) was a prominent American psychiatrist and psychoanalyst. Greenson is famous for being Marilyn Monroe's psychiatrist, and was the basis for Leo Rosten's 1963 novel, Captain Newman, M.D. The book was later made into a movie starring Gregory Peck as Greenson's character.
