Robert Silverberg has written more than 160 science fiction novels and nonfiction books. In his spare time he has edited over 60 anthologies. He began submitting stories to science fiction magazines when he was just 13. His first published story, entitled "Gorgon Planet," appeared in 1954 when he was a sophomore at Columbia University. In 1956 he won his first Hugo Award, for Most Promising New Author, and he hasn't stopped writing since. Among his standouts: the bestselling Lord Valentine trilogy, set on the planet of Majipoor, and the timeless classics "Dying Inside" and "A Time of Changes". Silverberg has won the prestigious Nebula Award an astonishing five times, and Hugo Awards on four separate occasions; he has been nominated for both awards more times that any other writer. In 2004, the Science Fiction and Fantasy Writers of America gave him their Grand Master award for career achievement, making him the only SF writer to win a major award in each of six consecutive decades.
