Jack Williamson published his first short story in 1928, and had been producing entertaining, thought-provoking science fiction ever since. The second person named Grand Master by the Science Fiction Writers of America, Williamson had 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 was a master of fantasy and horror as well as science fiction.
