Theodor Seuss Geisel was an American writer and cartoonist best known for his children's books written under the pen name Dr. Seuss, Theo Lesiège and in one case, the Rosetta Stone. He has published 44 children, which are often characterized by fictional characters, rhymes, and the frequent use of the counter trisillabici. His most famous books are the best-selling book Green Eggs and Ham, The Cat in the Hat, Fish Two Fish Red Fish Blue, The 'egg Horton, Horton Hears a Who, and How the Grinch Stole Christmas. Many adaptations of his works were created, including eleven television specials, three movies and a Broadway musical.
Geisel also worked as an illustrator for advertising campaigns, particularly for Flit and Standard Oil, and as a political cartoonist for PM, a newspaper in New York. During World War II, he worked in an entertainment service of Holy U. Army, where he wrote Design for Death, a film that later won the 1947 Academy Awards Documentary Feature. Geisel's birthday, March 2, was adopted as the date of the annual National Reading Day America, an initiative created by the reading of the National Education Association.
