I’m a biographer, novelist, and critic based in Oak Park, Illinois. My books include Astounding: John W. Campbell, Isaac Asimov, Robert A. Heinlein, L. Ron Hubbard, and the Golden Age of Science Fiction, which was a Hugo Award finalist and an Economist best book of the year; Inventor of the Future: The Visionary Life of Buckminster Fuller, a New York Times editors’ choice and one of Esquire’s fifty best biographies of all time; and Collisions, my upcoming biography of the physicist Luis W. Alvarez.
