This day in sketchtory, L. Ron Hubbard's published Dianetics: The Modern Science of Mental Health. With this book, Hubbard introduced a branch of self-help psychology called Dianetics, which quickly caught fire and, over time, morphed into a belief system boasting millions of subscribers: Scientology.

Hubbard was already a prolific and frequently published writer by the time he penned the book that would change his life. Under several pseudonyms in the 1930s, he published a great amount of pulp fiction, particularly in the science fiction and fantasy genres. In late 1949, having returned from serving in the Navy in World War II, Hubbard began publishing articles in the pages of Astounding Science Fiction, a magazine that published works by the likes of Isaac Asimov and Jack Williamson. Out of these grew the elephantine text known as Dianetics: The Modern Science of Mental Health.

In Dianetics, Hubbard explained that phenomena known as "engrams" (i.e. memories) were the cause of all psychological pain, which in turn harmed mental and physical health. He went on to claim that people could become "clear," achieving an exquisite state of clarity and mental liberation, by exorcising their engrams to an "auditor," or a listener acting as therapist.
