"Jack Williamson was one of the great science fiction writers. He did a series of novels which affected me as a young writer with dreams. I met him at 19, and he became my best friend and teacher."
-Ray Bradbury, quoted in the Los Angeles Times
"I have no hesitation in placing Jack Williamson on a plane with two other American giants, Isaac Asimov and Robert Heinlein."
-Arthur C. Clarke, author of 2001: A Space Odyssey
"Even though we don’t have Jack to share our lives any more, aren't we all incredibly lucky to have had him with us for so very long?"
-Frederik Pohl, friend and collaborator for 67 years
