Watch The Dentist and Dr. Suess

Meet Charles D. Cohen, a dentist by day and a world-class Dr. Suess expert by night. As a self-proclaimed Suessologist, he authored one of the best-known books on Dr. Suess, "The Seuss, The Whole Seuss, and Nothing But the Seuss." One of Cohen's biggest finds were some "lost" stories of Suess originally published in Redbook magazine. With his tenacity, those stories were published anew in 2011.
