Walter S. Bowman (1865-1938) was a professional photographer who worked in Pendleton, Oregon, from the late 1880s to the mid 1930s. Bowman's photographs document daily life in Eastern Oregon, including special events such as the Pendleton Round-Up. The collection consists of almost 800 negatives and prints representative of the span of the photographer's work, but his noted images of tribal people were largely destroyed after his death.
Photographs taken by Maj. Lee Moorhouse circa 1897- 1919 of Cayuse, Umatilla, and other Indians and their settlements in the Columbia River Basin and Umatilla County; landscapes in Oregon and Montana; and of the Round-Up in Pendleton, Or. and other locations.
