CAMBRIDGE, MA.- The Harvard University Art Museums presents Classified Documents: The Social Museum of Harvard University, 1903-1931, an exhibition featuring more than 100 original exhibition boards with photographs and graphical illustrations from the Social Museum collection, on display from January 20 through April 22, 2007 at the Arthur M. Sackler Museum. Established during the turbulent Progressive Era as the cornerstone of Harvard University’s new Department of Social Ethics, the Social Museum promoted a comparative study of social conditions and institutions—from health to housing, industry to government, education to crime, welfare to recreation, and race to religion—in America and abroad. The exhibition presents a compelling case study for a broader understanding of the development and use of social documentary photography, the graphic illustration of reform subjects, the techniques and strategies of exhibition display, and the role such museums played in the formation of the modern research university.
