Cleve Cartmill (1908 1964) was an American writer of science fiction and fantasy short stories. He is best remembered for what is sometimes referred to as "the Cleve Cartmill affair", when his 1944 story "Deadline" attracted the attention of the FBI by reason of its detailed description of a nuclear weapon similar to that being developed by the highly classified Manhattan Project. Before embarking on his career as a writer for pulp magazines, Cartmill had a number of jobs including newspaperman, radio operator and accountant, as well as, ironically, a short spell at the American Radium Products Company.
