The Angelus Studio was a professional photographic company located in Portland, Oregon. The collection includes works by George M. Weister (1862-1922) and Arthur M. Prentiss (circa 1865-1940) among the studio photographers; owner Fred Clark also acquired images by previous local photographers. The Angelus Studio collection provides extraordinary documentation of the city of Portland, the Lewis & Clark Exposition of 1905, Oregon landmarks, and commercial operations including logging and fish packing.
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.
