The Columbia River Plateau, in the interior Pacific Northwest, was populated for centuries by the Umatilla, Walla Walla, and Cayuse Indians. By the late nineteenth century, after the U.S. government had confined these peoples to a single reservation, their lives began to change irrevocably. Major Lee Moorhouse, a businessman and former militia officer, served as an Indian agent during this period. Believing that the Indians he encountered were a "dying race," Moorhouse was driven to collect their artifacts and, for posterity, take their photographs. Although he was not a professional photographer, Moorhouse produced more than 9,000 glass-plate negatives, one-third with Indians as his subjects. Some fifty of his images were published in 1906 in his popular Souvenir Album of Noted Indian Photographs, while others appeared as postcards, prints, or textual images. He reportedly sold 150,000 copies of his photograph The Cayuse Twins. While his works to some degree reflect a stereotypical view, they are an aid for tribal researchers and historians because they identify their subjects by name. In an era when others were seeing their Indian subjects as types, Moorhouse was aware that he was photographing people. In addition, his images record with some accuracy the everyday styles and dress of turn-of-the-century southern Plateau peoples." "This book marks the first major examination of Moorhouse and his work. Featuring eighty plates, it not only showcases Moorhouse's extensive photographs but also tells the story of the man and of the world in which he lived and worked.
