Cyril M. Kornbluth (July 2, 1923 – March 21, 1958) was an American science fiction author and a member of the Futurians. He used a variety of pen-names, including Cecil Corwin, S. D. Gottesman, Edward J. Bellin, Kenneth Falconer, Walter C. Davies, Simon Eisner, Jordan Park, Arthur Cooke, Paul Dennis Lavond, and Scott Mariner. The "M" in Kornbluth's name may have been in tribute to his wife, Mary Byers; Kornbluth's colleague and collaborator Frederik Pohl confirmed Kornbluth's lack of any actual middle name in at least one interview.
