Smith was an active contributor to Astounding Science Fiction during the Golden Age of Science Fiction in the 1940s. His collaboration with the magazine's editor, John W. Campbell, Jr. was interrupted when Campbell's first wife, Doña, left him in 1949 and married Smith. Smith continued regularly publishing science fiction novels and stories until 1960. He was given the First Fandom Hall of Fame award in 1980. He was a member of the all-male literary banqueting club the Trap Door Spiders, which served as the basis of Isaac Asimov's fictional group of mystery solvers the Black Widowers.
