Archival Collection 1: Office of the Principal Records, 1902-1970This collection contains administrative files related to the school’s Principals: Arthur L. Williston and Frederick E. Dobbs; and documentation related to the school’s founding. Most files relate to the distribution of scholarships, speeches, faculty meetings, war materials, relations with alumni, and the expansion of the Aircraft Engine Laboratory in the late 1940s. Most of these items are paper, with some photographs and newspaper clippings. The collection includes materials on the dispute over the expansion of the school to a three-year institution in the early 1920s. The collection also contains a large scrapbook collection, most of which focuses on the Evening School and Print Shop, and includes materials from newspapers, photographs, and other mixed media.
