The Williamson Effect

Jack Williamson has been writing groundbreaking science fiction since 1929, on topics as diverse as time travel (The Legion of Time), anti-matter (Seetee Shock), genetic engineering (Dragon's Island), and cybernetics (The Humanoids), earning him the title of Grand Master from the Science Fiction Writers of America. He's also produced seminal fantasies like Darker Than You Think and Golden Blood, a part of his oeuvre that won him the World Fantasy Award for Life Achievement.
Roger Zelazny, one of the most acclaimed writers of fantasy and science fiction, has brought together some of today's greatest SF writers to honor Williamson with terrific original stories either about Williamson himself or inspired by his works, coupled with original afterwords from the authors sharing their own fond remembrances of Williamson.
