A physicist and social activist, Edward G. Ramberg contributed to the early development of electron microscopy and color television, and devoted much of his life to pacifist and Quaker causes. Born in Italy to an American mother and German father, Ramberg experienced the losses of war firsthand during the First World War when his father was killed while serving with the German army. After moving to the United States with his mother, Ramberg attended Reed College and Cornell University before returning to Germany for postdoctoral study under Arnold Sommerfeld. Employed at RCA for most of his career (1935-1972), Ramberg refused any involvement in military or war-related research, and as a conscientious objector during the Second World War, was assigned to duty in Civilian Public Service camps. He continued to work in fostering social harmony until late in life. With his wife, Sarah Sargent, a Swarthmore graduate whom he met through the American Friends Service Committee, Ramberg helped to establish Bryn Gweled, a cooperative community in which people of various religious, social, and racial backgrounds lived and worked together. The bulk of the Ramberg papers consists of files pertaining to his work with Amnesty International, the American Friends Service Committee, and peace groups in the Philadelphia and Bucks County region. Of particular note is a bundle of correspondence with Sommerfeld.
