Paul Hoffman is the author of a memoir called King’s Gambit and two biographies, The Man Who Loved Only Numbers and Wings of Madness. Formerly the publisher of Encyclopaedia Britannica and the long-time editor in chief of Discover magazine, Hoffman has performed mathematical paper-folding tricks on David Letterman and strapped Oprah into a virtual hang-glider while she accused him of ogling her butt.
The winner of the first National Magazine Award for Feature Writing, he has written for the New Yorker, Atlantic Monthly, TIME, The New York Times, Seed, and Wired. He has delivered essays on NPR’s All Things Considered and hosted the five-part PBS series Great Minds of Science. Under the pseudonym Dr. Crypton, he has created mind-numbing puzzle contests. Chicago magazine once called Dr. Crypton “the smartest man in the world,” but they evidently caught him on a particularly good day.
