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.
Frederick Wallace Wilson (1872-1955) was an attorney and Circuit Court Judge in The Dalles, Oregon. The papers include correspondence, a letterpress copybook, legal papers, a manuscript, photographs, addresses and publications by Wilson as well as personal correspondence of Joseph G. Wilson, and certificates of Elizabeth Millar Wilson.
