He left Oxford University early because he had a great opportunity as an illustrator for "Vanity Fair." He ended up doing work for some major magazines as a cartoonists and illustrator. They considered him a genius. He published his first book in 1937 and when WWII began, he worked in the Army as an illustrator and movie producer; he even won an Academy Award for a documentary he did on the war.
Dr. Seuss was a great person and everyone knew that in one way or another he'd become famous and they were right. He was married to his first wife for 40 years before her death and he was then married for 23 years to his second wife up until he died at the age of 87 in 1991.
Dr. Seuss's honors include two Academy Awards, two Emmy Awards, a Peabody Award, the Laura Ingalls Wilder Medal, and the Pulitzer Prize. What's ironic is that a man who reached so many children with his books never had children of his own.
