Jack Williamson published his first short story in 1928, and he's been producing entertaining, thought-provoking science fiction ever since. The second person named Grand Master by the Science Fiction Writers of America--the first was Robert A. Heinlein--Williamson has always been in the forefront of the field, being the first to write fiction about genetic engineering (he invented the term), anti-matter, and other cutting-edge science. A renaissance man, Williamson is a master of fantasy and horror as well as science fiction. He lives in Portales, New Mexico.
