George Hoben Estabrooks (December 16, 1895 â December 30, 1973) was a Canadian-American psychologist and an authority on hypnosis during World War II. He was a Harvard University graduate, a Rhodes Scholar, and chairman of the Department of Psychology at Colgate University. By the 1920s, a handful of scientists, Estabrooks claimed, âÂÂhad learned how to split certain complex individuals into multiple personalities like Jeckyl-Hydes.â This technique was the most âÂÂfascinating and dangerous applications of hypnosis...used in military intelligence.âÂÂ
Estabrooks joined the First Canadian Division before he turned 20 becoming the youngest commissioned officer at that time. Years later, he became a 32nd degree Knight Templar Mason. He wrote 6 books throughout his life: Spiritism (1927), Man: The Mechanical Misfit (1941), Hypnotism (1943), The Future of the Human Mind (1961), Hypnosis: Current Problems (1962), Death in the Mind (1945).
Estabrooks consulted with the FBI regarding the effectivness of hyposis in interrogations of juvenile delinquents. During WWII, he helped the US military create "hypnotic couriers"âÂÂagents who could carry secret information in their subconscious without knowing they were doing so, making them "un-interrogatable."
In an interview with the Village Voice, Jane Roberts revealed that "Dr. Instream" was a pseudonym for Estabrooks in the Seth Material.
