Milton Henry Erickson, MD (1901 - 1980) was a psychiatrist and psychologist regarded by many as the foremost practitioner of medical hypnosis in his time. He wrote "Hypnotic Realities" and many other books dedicated to the "Art of Hypnosis" and which document the many things he learned while treating the many patients he encountered. He was a scientist and deeply gifted hypnotist. Erickson knew how to hypnotize people and could do so in an instant.
He was noted for his often unconventional approach to psychotherapy, such as described in the book Uncommon Therapy by Jay Haley; for his extensive use of therapeutic metaphor and story as well as hypnosis; and for coining the term Brief Therapy for his approach of addressing therapeutic changes in relatively few sessions, often only a single session.
