A celebrated academic and authority on Geisel's work, Pease presents a comprehensive look into the life of the artist and author best known as Dr. Seuss. Born into a prominent German family and raised in Springfield, Mass., young Geisel demonstrated his linguistic creativity early on, mixing German and English to create nonsense names for toys and imaginary animals; he also drew cartoons on the walls in every room of his childhood home, improbably encouraged by his mother. As a student at Dartmouth, Geisel had limited enthusiasm for his studies, but fell in love with the Jack-O-Lantern, the college newspaper he wrote for and edited. It was at the Jack-O-Lantern Geisel would develop the whimsical Dr. Seuss persona that would define his profession and, to a great extent, his life. On a tour of Geisel's prolific career (he was, among other roles, an advertiser and political cartoonist), Pease analyzes the appeal and impact of Geisel's game-changing children's books (The Grinch Who Stole Christmas, Green Eggs and Ham, The Cat in the Hat, etc.) clearly and succinctly; the intricacies of Geisel's tumultuous personal life provide a sobering counterpart.
