"The Weapon" is a short story by the American science fiction writer Isaac Asimov. Written in September 1938 when Asimov was 18, it was first published in the May 1942 issue of Super Science Stories under a pseudonym, H.B. Ogden. Because of the pseudonym, Asimov forgot that this story had ever been published and so, assuming that it had been rejected and believing that he no longer had a copy of it, he omitted it from The Early Asimov (1972), a collection of his earliest stories. In that book he listed "The Weapon" among eleven of his short stories that had been lost forever. However, while writing the first volume of his autobiography, In Memory Yet Green (1979), Asimov came across an entry in his diary which reminded him that the story had indeed been published. Obtaining a copy of the relevant magazine, he ensured that the story was published in chapter 30 of that book. Source: Wikipedia (en)
