Frederik Pohl is one of the grand masters of science fiction with a career spanning over sixty years, both as a writer and an editor. He is adept whether writing on his own or in collaboration. His partnership with Cyril M. Kornbluth, which produced such classics as The Space Merchants (1953) and Wolfbane (1959), is legendary. He has also collaborated with Jack Williamson and I believe he is the only writer to have collaborated with both Isaac Asimov and Arthur C. Clarke. For much of the 1960s Pohl was tied up editing several SF magazines, most notably Galaxy and Worlds of If, but when he returned to writing fiction in the 1970s he produced a series of memorable books, including the Heechee series, which began with Gateway (1977), as well as Man Plus (1976), The Coming of the Quantum Cats (1986) and The World at the End of Time (1990). His work has won him many awards and accolades, including the following which won the Hugo in 1986.
