It's pretty much impossible to think of children's literature without thinking of Dr. Seuss, but in reality, his first wife, Helen Palmer Geisel, played a large role in the author's success.
Geisel helped Seuss write some of his most popular books, from creating the "Whos down in Whoville" from How the Grinch Stole Christmas, to writing the ending lines of When Horton Hears a Who. Geisel later became the vice president at Beginner Books, which was Seuss's publisher. While people in the industry knew of Geisel's influence on her husband's work, she rarely received recognition for helping to turn him into a literary sensation.
Despite the pair's literary success, Geisel faced several health challenges throughout her life. A surgery at age 33 removed her ovaries, and Seuss was often questioned by the media about why the pair didn't have any children. Geisel also struggled with Guillain-Barre syndrome, which attacks healthy cells.
After 40 years of marriage, Geisel felt trapped in a marriage that was no longer bound by love, but by business. She died by suicide, leaving behind a note that read, “I didn’t know whether to kill myself, burn the house down, or just go away and get lost." In the months following Geisel's death, it was revealed that Dr. Seuss had been having an affair with Audrey Stone Dimond, a close friend of the couple. The pair married less than a year later.
In recent years, Seuss's books have faced criticism for including characters with racial stereotypes from a Chinese character with lines for eyes to African men wearing grass skirts.
