Editor and agent Pohl started a career as a literary agent in 1937, but it was a sideline for him until after World War II, when he began doing it full-time. Pohl stopped being Asimov's agent—the only one the latter ever had—when he became editor from 1939 to 1943 of two pulp magazines, Astonishing Stories and Super Science Stories. In his autobiography, Pohl said that he stopped editing the two magazines at roughly the time of the German invasion of the Soviet Union in 1941.
