L. Ron Hubbard (1911–1986) was an American author of science fiction, fantasy, and adventure stories, as well as the founder of Church of Scientology. Before his later religious writings, he was a prolific pulp science fiction writer in the 1930s and 1940s and later returned to science fiction late in his career.

Hubbard’s early science fiction helped support the pulp magazine era, while his later Writers of the Future contest has helped launch the careers of many new authors. His legacy is complex, as he is both remembered as a genre writer and as a controversial religious figure.

Some of his notable works

  • Battlefield Earth – A large-scale science fiction novel about humanity’s rebellion against alien conquerors.

  • Mission Earth series – A ten-book satirical science fiction series.

  • Numerous pulp-era science fiction and adventure stories published in magazines.
