when did dr seuss start writing children's books
Dr. Seuss Geisel adopted the name "Dr. Seuss" as an undergraduate at Dartmouth College and a graduate student at the University of Oxford. He left Oxford in 1927 to begin his career as an illustrator and cartoonist for Vanity Fair, Life, and various other publications. He also worked as an illustrator for advertising campaigns, most notably for FLIT and Standard Oil, and as a political cartoonist for the New York newspaper PM. He published his first children's book And to Think That I Saw It on Mulberry Street in 1937. During World War II, he took a brief hiatus from children's literature and worked in an animation department of the United States Army where he produced several short films, including Design for Death, which later won the 1947 Academy Award for Best Documentary Feature.[4]
