Murray Leinster (1896-1975) (born William Fitzgerald Jenkins) was a mainstay of the pulp magazines of the 1920s and 1930s, and following World War II he broadened his audience by writing for radio, television, and Hollywood. Among his accomplishments, Leinster is credited with popularizing the notion of parallel universes and the concept of the internet.
