Science fiction and mystery author Philip Wylie sounds, from his Wikipedia page, like an interesting guy. His stories and novels (When Worlds Collide is the best known, and the only one Ive read) have been credited with inspiring some of popular entertainments most famous characters Superman, Flash Gordon, Doc Savage, and Travis McGee. Hes been both hailed as a feminist and condemned as a misogynist for his writings on women (I havent read the writings in question and so cant render a verdict).
But my present concern is with the following rather alarming anecdote:
As early as 1939, [Wylie] had written a story about the Germans making plutonium bombs in a cave in Colorado. The Paradise Crater, written for American Magazine, was, as Sam Moskowitz points out, rejected as too fantastic, but later was accepted by Bluebook, which turned the magazine over to Washington for approval. When Washington balked, the editor of Bluebook returned the manuscript to Harold Ober, Wylies agent, who had already been contacted by the CIA. Wylie, who had been put under house arrest, was told by an aggressive major that he [the major] would take Wylies life if necessary, to plug the leak. Wylie agreed to tear up the manuscript. But the decision was made to hold back publication instead. According to Moskowitz, Four months later, the Atom Bomb was dropped on Hiroshima and Bluebook asked to have the story back. It was published in the October, 1945 number. Wylie, through his own research, had learned enough about atomic weaponry to become a security risk [John W. Campbell, Jr., editor of Astounding Science Fiction, went through a similar experience when one of his authors submitted a story featuring an atomic bomb].
