Yes. Before the publication of Dianetics: The Modern Science of Mental Health in 1950 and the founding of Scientology in 1954, Mr. Hubbard enjoyed a successful two-decade career as a fiction writer. A luminary to the millions of pulp fiction devotees in the 1930s and 1940s, Mr. Hubbard was also one of the genre’s most prolific writers. He authored more than 200 short stories, novellas and novels under his own name and 15 pen names. His published works from that era encompassed adventure, detective, science fiction, western and fantasy. He also wrote Hollywood screenplays in that same time period─most notably the 15-part serialized Secret of Treasure Island for Columbia Pictures.
