On this day in 1904, Theodor Geisel, better known to the world as Dr. Seuss, the author and illustrator of such beloved children's books as "The Cat in the Hat" and "Green Eggs and Ham," is born in Springfield, Massachusetts.
Geisel, who used his middle name (which was also his mother's maiden name) as his pen name, wrote 48 books--including some for adults--that have sold well over 200 million copies and been translated into multiple languages.
