Frederik Pohl
Pohl began writing in the late 1930s, using pseudonyms for most of his early works. His first publication was the poem "Elegy to a Dead Satellite: Luna" under the name of Elton Andrews, in the October 1937 issue of "Amazing Stories", edited by T. O'Conor Sloane. (Pohl asked readers 30 years later, "we would take it as a personal favor if no one ever looked it up".) His first story, the collaboration with C.M. Kornbluth "Before the Universe", appeared in 1940 under the pseudonym S.D. Gottesman.
