Joseph P. Gill (July 13, 1919 - December 17, 2006) was an American magazine writer and highly prolific comic book scripter. Most of his work was for Charlton Comics, where he co-created the superheroes Captain Atom, Peacemaker, and Judomaster, among others. Comics historians consider Gill a top contender as the comic-book field's most prolific writer. Per historian and columnist Mark Evanier, Gill "wrote a staggering number of comics. There are a half-dozen guys in his category. If someone came back and said he was the most prolific ever, no one would be surprised."
