Arguably the greatest science fiction writer who ever lived, Isaac Asimov also possessed one of the most brilliant and original minds of our time. His accessible style and far-reaching interests in subjects ranging from science to humor to history earned him the nickname "the Great Explainer." I. Asimov is his personal story--vivid, open, and honest--as only Asimov himself could tell it. Here is the story of the paradoxical genius who wrote of travel to the stars yet refused to fly in airplanes; who imagined alien universes and vast galactic civilizations while staying home to write; who compulsively authored more than 470 books yet still found the time to share his ideas with some of the great minds of our century. Here are his wide-ranging thoughts and sharp-eyed observations on everything from religion to politics, love and divorce, friendship and Hollywood, fame and mortality. Here, too, is a riveting behind-the-scenes look at the varied personalities--Campbell, Ellison, Heinlein, Clarke, del Rey, Silverberg, and others--who along with Asimov helped shape science fiction.
