Gertrude Stein (1874-1946) was a writer, art-collector, and advocate for the avant-garde. Born in Pennsylvania, she studied psychology at Harvard and attended medical school, dropping out in her fourth year to move to Paris with her brother Leo.

Here she played a crucial role in shaping the burgeoning European avant-garde, hosting literary salons that counted Pablo Picasso, Henri Matisse and Ernest Hemingway among the visitors. She was the author of countless poems, plays and shorter works, as well as books including Three Lives, The Making of the Americans, Tender Buttons and The Autobiography of Alice B. Toklas - a memoir written in the voice of her life partner of many decades, Alice.

Clement Hurd (1908–1988) is best known for illustrating Goodnight Moon and The Runaway Bunny, the classic picture books by Margaret Wise Brown. He studied painting in Paris with Fernand Léger and others in the early 1930s. After his return to the United States in 1935, he began to work in children's books.

He illustrated more than one hundred books, many of them with his wife, Edith Thacher Hurd, including the Johnny Lion books, The Day the Sun Danced, and The Merry Chase. A native of New York City, he lived most of his life in Vermont and California.
