Who is Dr. Seuss?
Dr. Seuss was the pen name of Theodor Seuss Geisel, an American children’s author, illustrator, animator and cartoonist. He picked up the name as a student at Dartmouth College and at Oxford, then worked as an illustrator and cartoonist for Vanity Fair, Life and advertising campaigns.
His first children’s book, And to Think That I Saw It on Mulberry Street, came out in 1937. After World War II he wrote the books that made him a household name, including Horton Hears a Who!, The Cat in the Hat, How the Grinch Stole Christmas!, Green Eggs and Ham, The Lorax and Oh, the Places You’ll Go! His books had sold more than 600 million copies by the time he died.
On Tuesdays with Stories #679, Green Eggs and Ham comes up twice: an SNL sketch built on the book went viral, and one host has been doing a bit about reading it as a parent for years.
