History: The North American Indian By Edward S. Curtis

Around 1922 Curtis moved to Los Angeles with his daughter Beth, and opened a new photo studio. To earn money he worked as an assistant cameraman for Cecil B. DeMille and was an uncredited assistant cameraman in the 1923 filming of The Ten Commandments. On October 16, 1924 Curtis sold the rights to his ethnographic motion picture In the Land of the Head-Hunters to the American Museum of Natural History. He was paid $1,500 for the master print and the original camera negative. It had cost him over $20,000 to film.

In 1927 after returning from Alaska to Seattle with his daughter Beth, he was arrested for failure to pay alimony over the preceding 7 years. The total owed was $4,500, but the charges were dropped. For Christmas of 1927, the family was reunited at daughter Florence's home in Medford, Oregon. This was the first time since the divorce that Curtis was with all of his children at the same time, and it had been thirteen years since he had seen Katherine. In 1928, desperate for cash, Edward sold the rights to his project to J.P Morgan's son. In 1930 he published the concluding volume of The North American Indian. In total about 280 sets were sold of his now completed opus magnum. In 1930 his ex-wife, Clara, was still living in Seattle operating the photo studio with their daughter Katherine. His other daughter, Florence Curtis, was still living in Medford, Oregon with her husband Henry Graybill. In 1932, Clara, drowned while rowing in Puget Sound, and his daughter, Katherine moved to California to be closer to her father and her sister, Beth.
