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.
Randall Vause Mills joined the University of Oregon English faculty in 1938. In addition to his teaching responsibilities, Mills wrote two books and numerous articles on transportation in the Pacific Northwest. He also wrote articles on bridge construction and location. In addition, Mills was interested in folklore, and was the founder and first president of the Oregon Folklore Society. The collection largely consists of correspondence, manuscripts, research material and notecards, printed material, photographs, and scrapbooks pertaining to transportation in the Pacific Northwest and folklore.
