Robert Silverberg (b. 1935) sold his first science fiction stories to the lower-grade pulps in the mid-fifties, moved swiftly to the three prestigious magazines ( Astounding, Galaxyand The Magazine of Fantasy & Science Fiction) and as his style deepened and themes expanded in through the next reached the first rank of science fiction writers. He is regarded as the greatest living writer of science fiction, an SFWA Grandmaster, ex-President (in the 1960's) of that organization, winner of five Nebulas, four Hugos and many other domestic and foreign awards. Among his famous novels are Dying Inside, The Book of Skulls, Downward to the Earth, A Time of Changes; his novella Born with the Dead(1974) is perhaps the finest work of that length published within the genre. Shifting to a predominating fantasy in the late 1970's ( Lord Valentine's Castleand the attendant Majipoor Series), Silverberg continued to write science fiction and won a Nebula in 1986 for the novella Sailing to Byzantium, and Hugos for the novelettes Gilgamesh in the Outbackand Enter a Soldier: Later, Enter Another. He was editor of the long-running original anthology series New Dimensions and of important reprint anthologies such as The Science Fiction Hall of Fame, Alpha, and The Arbor House Treasury of Modern Science Fiction.
