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.
John A. Winter (dates unknown) was one of Eugene's earliest photographers and maintained a studio there 1864-1886 in addition to working in Albany and Brownsville. His son, Clarence, kept the Eugene studio from 1886-1907 and then moved north to Portland and Seattle. The Winter studio collection consists of 37 images, primarily portraits.
