From about 1959 until 1969, Pohl edited "Galaxy" and its sister magazine "If"; the latter won three successive annual Hugo Awards as the year's best professional magazine. His 1977 novel "Gateway" won four "year's best novel" awards: the Hugo voted by convention participants, the Locus voted by magazine subscribers, the Nebula voted by American science-fiction writers, and the juried academic John W. Campbell Memorial Award. He won the Campbell Memorial Award again for the 1984 collection of novellas "The Years of the City", one of two repeat winners during the first 40 years. For his 1979 novel "Jem", Pohl won a U.S. National Book Award in the one-year category Science Fiction, and it was a finalist for three other year's best novel awards. He won four Hugo and three Nebula Awards, including receiving both for the 1977 novel "Gateway".
