Dr. Seuss is quite simply the most beloved children's book author of all time. Charles D. Cohen is a graduate of Haverford College and the Tufts University School of Dental Medicine and has been a practicing dentist for more than 18 years. Dr. Cohen first became enchanted with the works of Dr. Seuss as a child and he began purchasing early edition of Seuss books in college. Today, Dr. Cohen's trove of Seussiana is likely the most comprehensive private collection in the world. It is his hope to create a museum to preserve the full Seuss legacy by protecting the pieces for posterity. He is the author of the The Seuss, the Whole Seuss, and Nothing But the Seuss, and lives in South Deerfield, Massachusetts.
