Dr. Seuss was born Theodor Geisel in Springfield, Massachusetts, on March 2, 1904. After graduating from Dartmouth College in 1925, he went to Oxford University, intending to acquire a doctorate in literature. At Oxford, Geisel met Helen Palmer, whom he wed in 1927. Upon his return to America later that year, Geisel published cartoons and humorous articles for Judge, the leading humor magazine in America at that time. His cartoons also appeared in major magazines such as Life, Vanity Fair, and Liberty. Geisel gained national exposure when he won an advertising contract for an insecticide called Flit. He coined the phrase, "Quick, Henry, the Flit!" which became a popular expression.

Geisel published his first children's book, And to Think That I Saw It on Mulberry Street, in 1937, after 27 publishers rejected it.

Winner of the Pulitzer Prize in 1984, an Academy Award, three Emmy Awards, three Grammy Awards, and three Caldecott Honors, Geisel wrote and illustrated 44 books. While Theodor Geisel died on September 24, 1991, Dr. Seuss lives on, inspiring generations of children of all ages to explore the joys of reading.
