John J. (John Joseph) McGuire

Born in Altoona, Pennsylvania, in 1917, John J. McGuire was an American science fiction writer whose work appeared during the lively magazine-and-paperback era of the genre. He is especially associated with H. Beam Piper, with whom he wrote several well-known stories and novels.

Among the books linked to his name are Crisis in 2140, Lone Star Planet (also known as A Planet for Texans), Four-Day Planet, and The Return. His fiction is often remembered for its brisk storytelling, adventurous setups, and classic mid-century science fiction feel.

McGuire died in 1981. Reliable biographical information on him is fairly sparse, but the available sources agree on his dates and on his importance as one of Piper's key collaborators.
