As the iconic character of Sam-I-Am in the Seuss classic Green Eggs and Ham, the rhyming character is known by every child who has read a Dr. Seuss book.

One of Seuss’ beginner books, the culinary masterpiece of ham and some green eggs has made its way into millions of households around the world.

Sam-I-Am encourages his friend Guy-Am-I to enjoy a nice big plate of green eggs and ham. And he follows him around until Sam tries them.

While there’s not much of a moralistic undertone to Sam-I-Am’s story, it doesn’t stop him from being a special part of childhood history.

Perched on top of Whoville, the Grinch watches over Whoville with a disapproving eye. Unlike the people of Whoville, The Grinch is not a fan of Christmas.

Through the Grinch’s story, readers everywhere see the power of a little holiday spirit and a lot of love.

Many Dr. Seuss books include a layer of political and social commentary.

Most famous is the story of The Lorax.

The Lorax is the voice of the environment. He weaves a story about what happens when we don’t treat the environment like it should be treated.

As the voice for the trees in the forest, the character works to remind everyone of the destruction that can come if we ignore nature.

While the sweet Lorax is a favorite of children everywhere, his story was also a favorite of the author.

6. Cindy Lou Who

With her towhead, blonde hair and her angelic little smile, Cindy Lou Who melted the hearts of the Grinch and everyone who reads How the Grinch Stole Christmas!

A widely-known favorite, Cindy Lou Who represents the spirit of Christmas.

She is the one character who cared enough about the Grinch to look past his obvious faults.

Cindy Lou Who’s gentle nature and giving spirit give life to the town of Whoville and to the heart of the Grinch.

7. The Cat in the Hat

As a pivotal character in Oh, The Places You’ll Go! and — much more slyly — in each of Dr. Seuss’ books, you’re a favorite character as well!

In his children’s books, Dr. Seuss invites each reader along for the ride.

By encouraging ourselves to try new things or to think a little more about the world we all live in, all of us can often be the You in Seuss’ stories.

Whether you’re watching Whoville from above as the Grinch or making things right as Horton. Whether you’re melting the hardness from a green creature’s heart as Cindy Lou Who or causing mischief in the home of your new friends Conrad and Sally.

Or whether you’re encouraging your friends to try new things as Sam I Am or making big messes as Thing 1 or Thing 2… The most important character in Dr. Seuss’ books is you!

The Magic of Dr. Seuss Book Characters

As a prolific writer of children’s books and teller of tales, Dr. Seuss invites readers of all ages to hop into a sillier, more fun universe than the one they may find themselves living in.

All in all, he invites us to join the party. His characters show us the joy in making messes, in caring for people, and in using our imaginations.

From spinning tales of silliness in sitting rooms or jumping among the trees in a magical forest, the tales of Dr. Seuss are far and wide some of the most special books of all time.

There’s no shortage of Dr. Seuss books to enjoy. And there’s no shortage of Dr. Seuss characters to know and to love.

While the Grinch, Cindy Lou Who, the Cat in the Hat, and Thing 1 and Two are some of our favorites, Dr. Seuss’ books are chock full of many zany, interesting, and downright weird characters.
