Today is Theodor “Dr. Seuss” Geisel’s birthday! With their whimsical illustrations and trademark Seussian silliness, Dr. Seuss’s books have inspired generations of children to become lifelong readers. They’re a staple in my children’s library and were in mine growing up.

Learn more about Theodor “Dr. Seuss” Geisel and find all his books in the Dr. Seuss Amazon Author Store.

Here are some favorites:

The Lorax – Long before saving the earth became a global concern, Dr. Seuss warned against mindless progress and the danger it posed to the earth’s natural beauty. The Lorax is an ecological warning that still rings true today amidst the dangers of clear-cutting, pollution, and disregard for the earth’s environment.

Horton Hears a Who and Horton Hatches the Egg – Surely among the most lovable of all Dr. Seuss creations, Horton the Elephant represents kindness, trustworthiness, loyalty and perseverance. Now, the two books that introduced the heroic Horton to the world – Horton Hears A Who! and Horton Hatches the Egg – are available together for the first time in the Dr. Seuss’s Horton Collection Boxed Set.

Green Eggs and Ham – We can’t leave out Sam I Am now, can we?

A great companion of any Dr. Seuss books is the Green Eggs and Ham Cookbook with its Seuss-inspired recipes.
