Cleve Cartmill

Cleve Cartmill (June 21, 1908 in Platteville, Wisconsin – February 11, 1964 in Orange County, California) 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.
