Ingri d'Aulaire (December 27, 1904 – October 24, 1980) and Edgar Parin d'Aulaire (September 30, 1898 – May 1, 1986) were American 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. Background Edgar Parin, originally of Swiss citizenship, was born in Munich, Germany to an Italian portrait painter Gino Parin and Ella Auler, a talented artist and musician who had moved from St. Louis to Paris. His parents separated when Parin was six years old and he grew up spending time with each, travelling around Europe with his father. Edgar Parin took his mother's maiden name when she changed it from Auler to d'Aulaire. After studying architecture for a year in Munich, he began art studies at its School of Arts and Crafts (German:Kunstgewerbeschule). Edgar, a pupil of Hans Hofmann and Henri Matisse, studied fresco in Florence, painted murals in France and Norway, and exhibited in Paris, Berlin and Oslo. He illustrated many books in Germany from 1922 to 1926 and painted frescoes in Norway from 1926 to 1927. Ingri Mortenson was born in Kongsberg, Norway into an artistic family. Her uncle, for instance, was a clergyman and poet who translated the Icelandic Eddas into Norwegian and set his own poetry to music by Edvard Grieg. When she was 15, the Norwegian painter Harriet Backer encouraged her to pursue art as a career, and Ingri later studied at art schools in Norway, Germany and France. Ingri and Edgar met in Munich when Ingri was an art student. They were married in 1925. A modest insurance settlement following a near-fatal bus–trolley collision in Paris provided the seed money for Edgar's steerage-class voyage to the U.S. to scout for opportunities. He garnered enough commissions illustrating books to send for Ingri and they moved into a cold-water walk-up flat in Brooklyn in 1929. At first they pursued separate careers. Edgar concentrated on illustrating books using wood block engravings and stone lithography; Ingri garnered commissions to paint portraits of prominent businessmen. Their
