Grace Purdie Moon (1877-1947) and Carl Moon (1879- 1948) were American authors and illustrators of children's books about Native Americans. Carl Moon spent six years' apprenticing with various photographers in Cincinnati, Ohio, and Wheeling, West Virginia, before opening his own studio in Albuquerque, New Mexico. He met Grace Purdie in 1909, on a trip to the Grand Canyon where he had moved to work for the Fred Harvey Company. After their marriage, they moved to Pasadena, California, to open their own studio.
