Isaac Asimov (1920-1992) was a prolific science fiction writer and biochemist. During his lifetime, Asimov authored or edited over 500 books and served as president of the American Humanist Association. He also sported one of history's meanest set of mutton chops.

“Science fiction writers foresee the inevitable, and although problems and catastrophes may be inevitable, solutions are not.” -Isaac Asimov
