When we think of children's books, a lot of categories come to mind.

Picture books, board books, books for learning the alphabet or counting, and wordless books are the most appropriate for pre-readers aged between 0 to 5 years. Early reader books are meant for children aged between 5 to 7 years. Children in the age group of 7-12 years can read short and long chapter books and teenagers can read young adult fiction.

The most widely known books for children are written by Theodor Seuss Geisel, an American cartoonist and writer popularly known under the pen name Dr. Seuss. Children are an impressionable brood and so they must be exposed to a careful and an understanding choice of literary material. Geisel's children's books have imaginative characters and rhyme and they are the best reading material for children.

Geisel's books have even crossed the frontiers of children's domain. For example, The Lorax by Dr. Seuss, is a children's book that every business student must read. This book stresses the significance of preserving the natural resources carefully and delves on the importance of balance and vision in developing a business.

What is so special about Geisel's books? What makes Geisel's children's books so popular? Here are some exciting answers that will gratify your curiosity.

How Many Books Did Geisel Theodore Write?

Geisel wrote and published 40 books between the years 1937 and 1991. According to a study, his books have sold more than half a billion copies, possibly even more than Harry Potter books. His most popular books are Cat in the Hat published in 1957 and Green Eggs and Ham published in 1960. Most readers find Cat in the Hat hilarious, naughty, and funny. Green Eggs and Ham is a book that children and parents enjoy alike. The words in the Green Eggs and Ham book rhyme and stream.

Did Geisel's Writing Have An Impact On Children's Books?

Geisel's writing influenced the style of writing children's books. He transformed run-of-the-mill heroes into rebellious and defiant heroes. His books contain twisted plots and clever rhymes. The mutinous heroes in his books do something unexpected that stirs the ecstasy in children's minds. Dr.Seuss books are such a rave that one in every four American children receives Seuss as their first book.

Did He Write Any Controversial Book?

Geisel's Butter Battle Book published in 1984 is a controversial book. This book was removed from the public libraries during the cold war because it contains covert references to the arms race. The core theme of this book is the satirical depiction of a deadly war over something as trivial as breakfast food. The dispute is centred around an issue on how to eat the bread, whether with the butter side up or with the butter side down. This controversy is between Yooks and Zooks who live on the opposite sides of a long curving wall; a covert reference to the Berlin Wall. This children's book, though targeted for adults, remained on the New York Times best seller list for six months and also became New York Times Notable Book of the Year.

There are very talented authors and illustrators around, but when it comes to children's paperback, books by Theodore Geisel a.k.a Dr. Seuss take the cake.
