Arnold Castle
A little-known science fiction writer whose short stories appeared in American genre magazines in the 1950s and 1960s, he wrote brisk, idea-driven tales like The Perfectionists and When Day is Done. Because so little biographical information survives online, his work tends to speak louder than his personal history.

About the author
Arnold Castle is credited online as an American science fiction author active around 1960. Public-domain library and catalog pages link him to stories including The Invisible Enemy, A Mixture of Genius, The Perfectionists, and When Day is Done, which appeared in magazines such as Imagination, IF, and Amazing Science Fiction Stories.
What makes Castle interesting today is partly the mystery around him. Reliable biographical details are scarce, and I could not confirm basics such as his birth and death dates from the sources I found. What is clear is that his fiction has remained accessible through archival and public-domain projects, helping modern readers rediscover his compact, mid-century science fiction.
If you enjoy magazine-era SF with strong premises and a quick pace, Castle is one of those authors worth stumbling across. Even with only a handful of readily available stories, he offers a snapshot of the imaginative, economical storytelling that defined much of classic pulp and digest science fiction.
