Carl Selwyn

Carl Selwyn was the pen name of Carl Selwyn Pugh Jr., an American science fiction writer remembered for his energetic pulp adventures. Reliable online sources available here connect him especially with Planet Stories and identify him as active in the 1940s.

His fiction includes titles such as Revolt on the Earth-Star, Exiles of the Three Red Moons, Venus Has Green Eyes, The Citadel of Death, Space Bat, Earth Is Missing!, and Ice Planet. Readers who enjoy classic magazine-era science fiction often find his work appealing for its quick pace, imaginative settings, and old-school sense of wonder.

A later critical overview describes his career as unusually sudden and prolific, noting that he quickly became one of the notable contributors to Planet Stories. Even though biographical details are limited in the sources I could confirm, his stories have remained visible through reprints and public-domain editions, which have helped keep his name alive for modern pulp SF readers.
