Theodor Seuss Geisel was a prolific American children's author and illustrator, poet, and filmmaker. Under the pen name Dr. Seuss, Geisel wrote and illustrated over sixty books, many of which are considered classics of children's literature and continue to sell millions of copies.
Born in Springfield, Massachusetts, Geisel earned his B.A. from Dartmouth College in 1925. After earning his graduate degree at Lincoln College, Oxford, he worked as an illustrator and humorist for several publications including Vanity Fair and Life. In 1937, he published And to Think That I Saw It on Mulberry Street. During WWII, Geisel worked in the United States Army's animation and film department. In the decades following the war, Geisel released a string of classic Dr. Seuss books, such as The Cat in the Hat, Green Eggs and Ham, and One Fish Two Fish Red Fish Blue Fish. Most Dr. Seuss books are written in anapestic tetrameter.
Although Dr. Seuss Enterprises decided in 2021 to stop publication on several titles for racist depictions, other titles in the Dr. Seuss canon promote themes such as anti-consumerism, anti-authoritarianism, and racial equality. In 1984, Dr. Seuss was awarded the Pulitzer Prize for his contribution to children's literature.
