News that was released on Theodor Seuss Geisel’s (aka Dr. Seuss’) birthday that six of his books were being canceled for future publication unleased a torrent of criticism, support and ridicule on social media.

Six Dr. Seuss books — including “And to Think That I Saw It on Mulberry Street” and “If I Ran the Zoo” — will stop being published because of racist and insensitive imagery, the business that preserves and protects the author’s legacy said Tuesday.

“These books portray people in ways that are hurtful and wrong,” Dr. Seuss Enterprises told The Associated Press in a statement that coincided with the late author and illustrator’s birthday.

“Ceasing sales of these books is only part of our commitment and our broader plan to ensure Dr. Seuss Enterprises’ catalog represents and supports all communities and families,” it said.

The other books affected are “McElligot’s Pool,” “On Beyond Zebra!,” “Scrambled Eggs Super!,” and “The Cat’s Quizzer.”

The decision to cease publication and sales of the books was made last year after months of discussion, the company told the AP.

“Dr. Seuss Enterprises listened and took feedback from our audiences including teachers, academics and specialists in the field as part of our review process. We then worked with a panel of experts, including educators, to review our catalog of titles,” it said.

Books by Geisel, who was born in Springfield, Massachusetts, on March 2, 1904, have been translated into dozens of languages as well as in braille and are sold in more than 100 countries. He died in 1991.

He remains popular, earning an estimated $33 million before taxes in 2020, up from just $9.5 million five years ago, the company said. Forbes listed him No. 2 on its highest-paid dead celebrities of 2020, behind only the late pop star Michael Jackson.

As adored as Dr. Seuss is by millions around the world for the positive values in many of his works, including environmentalism and tolerance, there has been increasing criticism in recent years over the way Blacks, Asians and others are drawn in some of his most beloved children’s books, as well as in his earlier advertising and propaganda illustrations.

The National Education Association, which founded Read Across America Day in 1998 and deliberately aligned it with Geisel’s birthday, has for several years deemphasized Seuss and encouraged a more diverse reading list for children.

School districts across the country have also moved away from Dr. Seuss, prompting Loudoun County, Virginia, schools just outside Washington, D.C., to douse rumors last month that they were banning the books entirely.

“Research in recent years has revealed strong racial undertones in many books written/illustrated by Dr. Seuss,” the school district said in a statement.

In 2017, a school librarian in Cambridge, Massachusetts, criticized a gift of 10 Seuss books from first lady Melania Trump, saying many of his works were “steeped in racist propaganda, caricatures, and harmful stereotypes.”

In 2018, a Dr. Seuss museum in his hometown of Springfield removed a mural that included an Asian stereotype.

“The Cat in the Hat,” one of Seuss’ most popular books, has received criticism, too, but will continue to be published for now.

Dr. Seuss Enterprises, however, said it is “committed to listening and learning and will continue to review our entire portfolio.”
