Foundation and Empire

"A true polymath, a superb rationalist, an exciting and accessible writer in both fiction and non-fiction, Isaac Asimov was simply a master of all he surveyed. Beloved entertainer, pioneer, author of many of the most endearing and lasting stories of the twentieth century, he will probably be best known as the creator of the idea that robots--our eternal servants--must play by the rules, even when they seem not to." -- Greg Bear
"Asimov served wondrous meals-of-the-mind to a civilization that was starved for clear thinking about the future. To this day, his visions spice our ongoing dinner-table conversation about human destiny." -- David Brin
"Isaac was still in his teens when I met him, a fan of mine before I was a fan of his. Writing for John W. Campbell back in the famous "golden age of science fiction," he became one of the founders of our field. With the robot stories and the Foundation stories, he helped to shape science fiction as we know it." -- Jack Williamson
"The extraordinary and grand concept which forms the basis of Asimov's trilogy was what drew me to science fiction originally." -- Brian W. Aldiss
"I grew up on the ABC's of science fiction--Asimov, Bradbury, Clarke. There's a reason Asimov's name comes first, and not just because of the alphabet!" -- Janis Ian
