 Within a year he placed three more stories in Gernsback's pulp magazines and one in "Astounding Stories", then edited by Harry Bates.But his only science fiction publication between 1932 and 1938 was "The Creator" ("Marvel Tales" #4, March–April 1935), a story with religious implications, which was then rare in the genre.Once John W. Campbell, at the helm of "Astounding" from October 1937, began redefining the field, Simak returned and was a regular contributor to "Astounding Science Fiction" (as it was renamed in 1938) throughout the Golden Age of Science Fiction (1938–1950).
