Stuart James Byrne (October 26, 1913 – September 23, 2011) was an American screenwriter and writer of science fiction and fantasy.

"[2] Favorite fiction memories of the time included Grimm's Fairy Tales, Alice in Wonderland, L. Frank Baum's Oz stories, the Rover Boys, the Boy Allies, Gernsback science fiction, and "the life-changing impact of the Edgar Rice Burroughs books.

Years later, he recalled that "many a summer night ... were spent in awe ... in the Pleiades and the great Orion Nebula, or surfing the moons of Jupiter and rings of Saturn.

It told how a young man sacrificed his life to send a passenger spaceship away from a fatal encounter with the sun.

According to Byrne, "The scenes and locale of the opening adventure in the Peruvian Andes are authenticated by the fact that I spent some years in those mouintains, following the trails of Pizarro while guided by archaic Spanish manuscript".

[2] Byrne also declared: "An ERB attorney once suggested to me that I try writing my own ERB-style fantasy adventures using my own characters.

He is credited as co-author with Clark Dalton of the two-part story called "Test Flight to Eden" (1975), which appeared in two consecutive Perry Rhodan books.

When there were financial problems publishing Perry Rhodan books due to a change in the exchange rate between German and US currencies, Byrne undertook to write the Star Man series, of which 11 appeared in print, published by Forrest J. Ackerman's Master Publications.
