Don Freeman was introduced to the world of children's literature when William Saroyan asked him to illustrate several books. Soon after, he began to write and illustrate his own books, a career he settled into comfortably and happily. Through his writing, he was able to create his own theater: "I love the flow of turning the pages, the suspense of what's next. Ideas just come at me and after me. It's all so natural. I work all the time, long into the night, and it's such a pleasure. I don't know when the time ends. I've never been happier in my life!"

Don died in 1978, after a long and successful career. He created many beloved characters in his lifetime, perhaps the most beloved among them a stuffed, overall-wearing bear named Corduroy.

Don Freeman was the author and illustrator of many popular books for children, including Corduroy, A Pocket for Corduroy, and the Caldecott Honor Book Fly High, Fly Low.
