Paul Hoffman

Paul Hoffman is the CEO of Liberty Science Center, the creative director of the Rubik's Cube Exhibition, and a co-owner of Rucola, a Northern Italian restaurant in Brooklyn. He is the author of the memoir King's Gambit: a Son, a Father, and the World's Most Dangerous Game and two biographies, The Man Who Loved Only Numbers and Wings of Madness, which Chris Wedge is turning into a feature film.

Paul 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. Under the pseudonym Dr. Crypton, he has created elaborate puzzle contests. Chicago magazine once called him "the smartest man in the world," but Paul says they caught him on a particularly good day.
