Clyde Brown

Clyde Brown appears to be an American science fiction writer known primarily for the short story First Man. Reliable catalog sources available here point to that story as his best-documented work, first published in Galaxy Science Fiction in April 1958.

Bibliographic records suggest First Man was reprinted and translated over time, which helps explain why Brown's name still surfaces in science fiction databases and public-domain collections. Beyond that, I couldn't confirm many personal biographical details from dependable sources, so this overview sticks to the published record rather than guessing at his life story.
