Dr. Seuss

Dr. Seuss, the pen name of Theodor Geisel, drew in a rubbery cartoon style honed in advertising. The Cat in the Hat of 1957, written from a limited word list after a challenge from his publisher, showed early readers could be wild and funny, and Green Eggs and Ham used only 50 different words. Some early books and wartime cartoons contain racist caricatures, and six titles were withdrawn by his estate in 2021.
