Cosmic Stories (also known as Cosmic Science-Fiction) and Stirring Science Stories were two American pulp science fiction magazines that published a total of seven issues in 1941 and 1942. Both Cosmic and Stirring were edited by Donald A. Wollheim and launched by the same publisher, appearing in alternate months. Wollheim had no budget at all for fiction, so he solicited stories from his friends among the Futurians, a group of young science fiction fans including James Blish and C. M. Kornbluth. Isaac Asimov contributed a story, but later insisted on payment after hearing that F. Orlin Tremaine, the editor of the competing science fiction magazine Comet, was irate at the idea of a magazine that might "siphon readership from magazines that paid",[1] and thought that authors who contributed should be blacklisted. Kornbluth was the most prolific contributor, under several pseudonyms; one of his stories, "Thirteen O'Clock", published under the pseudonym "Cecil Corwin", was very successful, and helped to make his reputation in the field. The magazines ceased publication in late 1941, but Wollheim was able to find a publisher for one further issue of Stirring Science Stories in March 1942 before war restrictions forced it to close again.
Other well-known writers who appeared in the two magazines included Damon Knight and David H. Keller. Knight's first published story, "Resilience", appeared in the February 1941 issue of Stirring Stories, but the story was ruined by a misprint in a crucial word in the first sentence. Keller was an established writer in the field, but Wollheim was aware that Keller occasionally donated material to fanzines, and was able to obtain a story from him. The quality of the artwork was variable; it included Elliot Dold's last artwork in the science fiction field, for the cover of the July 1941 issue of Cosmic Stories, and several covers and interior drawings by Hannes Bok, who later became a well-known artist in the field.
