About Ingri and Edgar Parin d'Aulaire
Ingri d'Aulaire and Edgar Parin d'Aulaire were writers and illustrators of children's books who worked primarily as a team, completing almost all of their well-known works together. The couple immigrated to the United States from Europe and worked on books that focused on history such as Abraham Lincoln, which won the 1940 Caldecott Medal. They were part of the group of immigrant artists composed of Feodor Rojankovsky, Roger Duvoisin, Ludwig Bemelmans, Miska Petersham and Tibor Gergely, who helped shape the Golden Age of picture books in mid-twentieth-century America. The d'Aulaires won the third annual Caldecott Medal in 1940 for Abraham Lincoln, a picture-book life of the 16th U.S. They won the 1953 Boy's Club award for their version of Buffalo Bill (1952).
