Lester del Rey (1915-1993) was born Leonard Knapp (but this became known only long after his death). After a spotty, abbreviated education and itinerant existence, he headed to New York where he became almost immediately a significant constituent of Astounding and John Campbell's celebrated Golden Age.Del Rey sold his first story to John Campbell in the first months of Campbell's editorship, and over the next several years he sold him many more, including his female-android story Helen O'Loy (1938), perhaps the first true science fiction romance, and Nerves (1942, novelized in 1956), a brilliant novella of atomic pile disruption, amazingly prescient of Three Mile Island and Chernobyl. Del Rey's apostolic and profoundly controversial short novel For I Am A Jealous People (1956), positing a malevolent Deity, is also very well known.Del Rey worked in the Scott Meredith Fee Department in the late 40s, edited science fiction magazines in the early 50s, published some noted juveniles (The Runaway Robot) in the mid-50s, and eventually became the founding editor of Del Rey Books, a fantasy and science fiction imprint under the aegis of Ballantine.In collaboration with his third wife, Judy-Lynn, del Rey's imprint became the most successful fantasy and science fiction publisher in history. The two of them nurtured fantasy writers like Stephen Donaldson, Anne McCaffrey, and Terry Brooks to bestselling status. In 1991, del Rey was named a Grand Master of the Science Fiction Writers of America. He died only a few months after his retirement from Ballantine.
