It is the birthday of pulp fiction writer L. Ron Hubbard (1911), who wrote for sci-fi and fantasy magazines in the 1930s. Hubbard also wrote romances, westerns, adventures, travel, and mysteries. His first full-length novel was Buckskin Brigades (1937).

His 10-volume Mission Earth series (1985-1987) tells the story of a CIA agent on the planet Voltar who exposes a plot by aliens to conquer Earth to use it as a base for invasion of the rest of the universe. The Voltar Confederacy sends a mission to Earth to prevent earthlings from destroying their own planet through pollution before it can be conquered. Hubbard also created the controversial Scientology religious movement.
