Marguerite de Angeli, née Lofft, was born in Lapeer, Michigan, and grew up in Philadelphia. At age 15, she began to sing professionally and left high school for more musical training. In 1910, she married John Dailey de Angeli, a violinist, with whom she had six children. In 1921, she began studying drawing and soon went on to illustrate first a Sunday school paper and then national magazines such as The Ladies' Home Journal. She illustrated books for authors including Dorothy Canfield Fisher. She published her own first book, Ted and Nina Go to the Grocery Store, in 1935. Over her 50-year career, she became one of the best-known and most highly-acclaimed author/illustrators in American children's literature. She won the Newbery Medal in 1950 for her most famous book, The Door in the Wall. She published her autobiography, Butter at the Old Price, in 1971.
