Dr. Seuss

Acclaimed American writer born Theodor Seuss Geisel (March 2, 1904 – September 24, 1991) was an American children's author and cartoonist. He is known for his work writing and illustrating more than 60 books under the pen name Dr. Seuss. His work includes many of the most popular children's books of all time, selling over 600 million copies and being translated into more than 20 languages by the time of his death. From Wikipedia.

After attending Dartmouth College and Oxford University, he began a career in advertising. His advertising cartoons, featuring Quick, Henry, the Flit!, appeared in several leading American magazines. Dr. Seuss's first children's book, titled "And To Think That I Saw It On Mulberry Street", hit the market in 1937, changing the face of children's literature forever. It was rejected 27 times before it was finally published by Vanguard Press in 1937.
