History of Dianetics begins around 1950. During the late 1940s, L. Ron Hubbard began developing a mental therapy system which he called Dianetics. Hubbard had tried to interest the medical profession in his techniques, including the Gerontological Society, the Journal of the American Medical Association, and the American Journal of Psychiatry, but his work was rejected for not containing sufficient evidence of efficacy to be acceptable. In April 1950, he published his ideas in Astounding Science Fiction where he was well-known as a science fiction writer. The article generated a lot of interest and the following month Hubbard published the book Dianetics: The Modern Science of Mental Health. The book brought in money and Hubbard began teaching courses through the Hubbard Dianetic Research Foundation. The scientific and medical communities were critical of Dianetics — the American Psychological Association called on psychologists to not use the techniques and complaints were made against local Dianetics practitioners for allegedly practicing medicine without a license. Financial problems ensued, but despite the influx of financial support from some wealthy followers, the first foundations resulted in bankruptcy and the loss of the name and copyrights to Dianetics. Around 1952, Hubbard went on to create Scientology, eventually regaining the rights to Dianetics which he incorporated into Scientology. Today, Dianetics is a part of Scientology and is used as a beginning promotion to new people. Origins The ideas of Dianetics originated in unpublished research L. Ron Hubbard supposedly performed in the 1920s and 1930s. He recorded the results and his conclusions in an unpublished 1938 manuscript, Excalibur, the contents of which formed the basis for some of his later publications. After Hubbard's service in the United States Navy during World War II, he was admitted to the Oak Knoll Naval Hospital in Oakland, California. While there, he claimed to have carried out research into endocrinology "to determine whether or not structure monitors function or function monitors structure ... using nothing but Freudian Psychoanalysis and using a park bench as a consulting room", spending a great deal of time in the hospital's library, where he would have encountered the work of Sigmund Freud and other psychoanalysts. The emergence of Dianetics In January 1949, Hubbard informed his literary agent, Forrest J. Ackerman, that he was writing a book on the "cause and cure of nervous tension", which he was going to call either The Dark Sword or Excalibur or Science
