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.
William Burke (dates unknown) photographed the Southern Oregon communities of Coos, Curry and Douglas counties from the 1900s to the 1930s. In 1912 Burke and F.F. Sasman traveled on a Pathfinder to demonstrate the need for better roads on the coast. The collection consists of 380 images, prints and negatives, of community events, shipping, railroads, logging, mining and ship-building, and the Pathfinder expedition.
