Just after college in 1927, Geisel and his wife moved to New York City where he became an illustrator for various publications and ads.
One of his most well-known accounts was Flit, a bug spray manufactured by Standard Oil; the campaign’s catchphrase “Quick, Henry, the Flit!” became part of pop culture vernacular and increased his demand and wealth tenfold.
His first book, “Boners,” topped The New York Times non-fiction bestseller list in 1931. However, his subsequent attempts at writing books failed to interest any publishers.
It was only through an old Dartmouth connection that he would finally publish “And to Think That I Saw It on Mulberry Street,” after nearly 40 rejections, in 1937.
