John J. (John Joseph) McGuire

Born in Altoona, Pennsylvania, on August 25, 1917, John J. McGuire was an American science fiction writer active during the pulp and digest-magazine era. He died on August 1, 1981.

He is most often remembered for collaborating with H. Beam Piper. Together they wrote works that later appeared as Crisis in 2140 and Lone Star Planet—stories known for mixing action, satire, and large-scale speculative ideas.

McGuire's name is closely tied to the rich world of 1950s science fiction magazines, where collaboration and serialization were a big part of the field. Even though he is less famous than some of his contemporaries, his fiction remains of interest to readers who enjoy classic space-age adventure and the history of science fiction.
