dr. seuss most memorable characters

Theodor Seuss Geisel, the man most of us know as Dr. Seuss came up with oodles of characters, most of whom are the greatest of all time.

He created characters like Bartholomew Cubbins, Thidwick the Big-Hearted Moose, The Grinch, The Lorax, and countless others.

Dr. Seuss was, undoubtedly, one of the greatest character creators and constructed his characters whose names typified not only their behaviors or attitudes but their physical appearance. The way you illustrated the characters made you agree that their given name was truly theirs.

Hats off!

I found it befitting to honor such a genius by coming up with a Dr. Seuss character list, a list that has his most memorable characters.

He wrote dozens of books and I assure you, you won’t know all these characters, but if you’re a super fan, you might know more than half.

Who Was Dr. Seuss?

Dr. Seuss was born Theodor Seuss Geisel on March 2, 1904, in Springfield, Massachusetts, U.S. His father’s name is Theodor Robert Geisel and his mother was Henrietta Seuss Geisel. Dr. Seuss was his pen name and it’s way more famous than his real name. Throughout his career, Dr. Seuss published over 60 books, the first of which was a children’s book called And to Think That I Saw It on Mulberry Street, which was published in 1937.

As a young man, Geisel’s life had already started following a trajectory that’d eventually lead him to fame as a writer. While at Dartmouth College, he became the editor-in-chief of its humor magazine, Jack-O-Lantern which later dropped him after a drinking misdemeanor but managed to contribute to the magazine using the pseudonym “Seuss.”

Geisel later attended the University of Oxford in England but he dropped out. Geisel married Helen Palmer, a lady he met while studying at Oxford.

The couple later returned to America and Geisel decided to become a full-time writer and cartoonist, working for several institutions including LIFE and Vanity Fair, Saturday Evening Post, the New York Weekly Judge, Standard Oil, and Viking Press, among others.

Several of Geisel’s books were adapted into animated films during his lifetime and posthumously. His works also won Geisel numerous awards, including a Pulitzer in 1984, three Emmys, three Grammys, and an Academy Award.

Geisel’s and Palmer’s story wasn’t a ‘happy ever after’ because by October 1967, Geisel was having an affair with the couple’s longtime friend Audrey Stone Dimond, and cancer-stricken Palmer decided to end the emotional pain caused by an affair by committing suicide.
