Collection contains photographs of faculty, staff, and students, 1910-1973, with the bulk of the images from 1965-1973. Most of the photos appear to be identification images, some of which show signs of having been posted on display. There are also images of Prof. William Webster Hansen; the farewell party for Ed. A. Wright (mechanician) in 1942; Prof. Fernando Sanford with a group on the steps of a house ca. 1910; and undated portraits of 19th century German physicists: Max Planck, Gustav Kirchhoff, Hermann von Helmholtz, and two others.
