For decades, readers have enjoyed the stories and illustrations of Theodor Seuss Geisel—Dr. Seuss. Famous for his children’s books, Dr. Seuss’s political cartoons have remained largely unknown. From 1941 to 1943, Seuss served as chief editorial cartoonist for the New York liberal newspaper PM, and his work commented on issues of the day. His political cartoons during World War II denounced isolationism, racism and anti-Semitism. They sold war bonds and attacked Hitler, Mussolini and the Japanese in a manner that melded message, fantasy and reality in a uniquely Seussian style. The influence of Dr. Seuss’s work at PM could later be seen throughout his whimsical children's books, where he employed serious themes such as fairness, tolerance and democracy in his quest to enlist everyone to help make a better world.
