News • A newly discovered Dr. Seuss manuscript will celebrate America’s 250th anniversary • Oct. 28, 2025, 12:56 PM ET (AP)Dr. Seuss (born March 2, 1904, Springfield, Massachusetts, U.S.—died September 24, 1991, La Jolla, California) was an American writer and illustrator of immensely popular children’s books noted for their nonsense words, playful rhymes, and unusual creatures.
Early career and first Dr. Seuss booksAfter graduating from Dartmouth College (B.A., 1925), Geisel did postgraduate studies at Lincoln College, Oxford, and at the Sorbonne. He subsequently began working for Life, Vanity Fair, and other publications as an illustrator and humorist. In addition, he found success in advertising, providing illustrations for a number of campaigns. Geisel was especially noted for his work on ads for Flit insect repellent. Some of his characters later appeared in his children’s works.
After illustrating a series of humor books, Geisel decided to write a children’s book, which was reportedly rejected by nearly 30 publishers. After his chance meeting with a friend who was an editor at Vanguard Press, And to Think That I Saw It on Mulberry Street was finally released in 1937. The work centers on a young boy who transforms his ordinary walk home from school into a fantastical story. Later, however, he describes only the facts of his walk to his father, who frowns on the boy’s imaginative nature. Geisel used the pen name Dr. Seuss, planning to publish novels under his surname; the Dr. was a tongue-in-cheek reference to his uncompleted doctorate degree. However, his first book for adults, The Seven Lady Godivas (1939), fared poorly, and thereafter he focused on children’s books, which he preferred. (In many profiles and articles, he is often quoted as hing said, “Adults are obsolete children, and the hell with them.” In 1986 he published a humor book on aging “for readers of all ages,” You’re Only Old Once! A Book for Obsolete Children.)
After publishing several more children’s works, Geisel released Horton Hatches the Egg in 1940. With it, he introduced the features that would come to define his books: a unique brand of humor, playful use of words, and outlandish characters. It centers on an elephant who is duped into sitting on the egg of a bird who goes on vacation. Despite various hardships, Horton refuses to lee: “I meant what I said, and I said what I meant. An elephant’s faithful one hundred percent!” In the end, he is rewarded when the egg hatches, and a creature with bird wings and an elephant’s head emerges.
World War II and documentariesDuring World War II Geisel’s focus shifted to politics. In the early 1940s he was an editorial cartoonist at PM magazine in New York City. Although his political cartoons pointedly critiqued American isolationism and “America First” attitudes, some of them also contained xenophobic and sexist tropes and racist depictions of Asians (in particular, Japanese people), Arabs, and Africans. Geisel then served (1943–46) in the U.S. Army, where he was assigned to the documentary division. In 1945 he wrote Your Job in Germany, which was directed by Frank Capra; it was later remade as the Academy Award-winning Hitler Lives (1945), though Geisel was not credited. After his service ended, he continued to make films. With his first wife, Helen Palmer Geisel, he wrote the Oscar-winning documentary feature Design for Death (1947). His animated cartoon Gerald McBoing-Boing (1950) also won an Academy Award.
