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.
Bailey Millard (1859-1941) was a printer, journalist and publisher who published works by upcoming authors like Jack London and Joaquin Miller. The collection includes correspondence, an autobiography, a biography of Edwin Markham, two albums of Oregon life in the 1880s-1890s, and eight images of literary figures including Jack London, Frank Norris, Edwin Markham, David Graham Phillips, and Robert Louis Stevenson.
