Robert J. Cashman Papers, 1928-1988 19 boxes (including two legal size) Series 11/3/21/4 Cashman, Robert J., 1906-1988 This collection documents the work of Robert J. Cashman, who served as a professor of physics at Northwestern University from 1936 to 1975. His early research interests focused on photovoltaic and photoemissive cells. Later, he developed a more stable thallous sulfide photoconductive cell. His cells were widely used in optical communications systems and in infrared astronomy. These papers fill 19 boxes and span the period 1928-1988. The papers are organized in six main categories: biographical materials, education files, correspondence, teaching files, research and consulting files, and publications.

Robert Joseph Cashman was born on September 27, 1906, in Wilmington, Ohio. After obtaining his B.A. (physics) at Bethany College in 1928, he entered Northwestern University where he earned his M.A. (1930) and Ph.D. (1935) in physics.

In 1936 Cashman joined the Northwestern faculty as an assistant professor of physics. He was promoted to associate professor in 1941 and professor in 1947. He retired in 1975 as professor emeritus.

Cashman's early research interests in photovoltaic and photoemissive cells culminated in the development of cells which were used early in World War II. The gradual deterioration of these cells, however, led him to develop a stable thallous sulfide photoconductive cell which was more useful. During and after the War Cashman directed several military research projects along these and related lines. His cells were widely used in optical communications systems and in infrared astronomy. He obtained seven patents for these cells.

On June 8, 1940, Cashman married Agnes E. Jones (see Series 25/5), an assistant professor of physical education at Northwestern. The couple had two children, John and Linda Cashman Modine.

Robert J. Cashman died on September 27, 1988.

 Scope and Contents of Collection

The Robert J. Cashman Papers fill 19 boxes and span the period 1928-1988. The papers are organized in six main categories: biographical materials, education files, correspondence, teaching files, research and consulting files, and publications.

The biographical materials include curricula vitae, clippings (primarily about his research, although there are here several articles setting Cashman's work in the development of the related fields), and programs of meetings at which he spoke.

The education files consist primarily of Cashman's notes on lectures and reading, and laboratory experiments.

The general correspondence concerns teaching, research, and other professional matters; there is little personal correspondence. Of interest is a small collection of letters related to Cashman's joint work with Walter S. Huxford on a "sunburnometer."

The teaching files include lecture notes, problems, grade and registration records, examination sheets, and some student subject guides.

The research and consulting files occupy nine boxes and form the largest category in the papers. The bulk of these materials consists of reports, correspondence, experimental data, and material relating to administrative matters. In addition to his research for the Navy, Army Air Force, and the National Defense Research Committee, Cashman worked as a consultant for Capehart-Farnsworth Corp., General Electric Co., and the Research Corp. Four substantial folders of correspondence and patent materials concern Cashman's legal advisors, Mann and Brown. The documents in these files deal with infringements, potential infringements, and other procedures. Users interested in these aspects of Cashman's work should also consult specific patent records (Box 16, Folders 1-9) and pertinent periods in the general correspondence. Eleven of Cashman's laboratory notebooks (or sections thereof) are located in the two legal size boxes (Boxes 18 and 19).

The publications contain drafts and reprints of some of Cashman's articles and related correspondence.

 Provenance and Acquisition Information

The Robert J. Cashman Papers were donated to the University Archives by John E. Cashman (son) and Linda Cashman Modine (daughter) on August 28, 1989, June 19, 1992, May 13, 1993, July 16, 1993, and July 20, 1993 as Accession nos. 89-166, 92-57, and 93-67, and 93-95.

 Processing Information

This collection was processed by William K. Beatty in June - December 1993.

 Materials Separated from Collection

Several group and individual photographs of Cashman were transferred to the Archives' photographic collection. A disk for a prototype electronic organ (which was to utilize a photovoltaic cell) was transferred to the Archives' audiovisual collection. Approximately 20 linear inches of materials related to Northwestern University, but not to Cashman, were transferred to the Archives general files. Approximately 50 linear inches of duplicate and 30 linear inches of extraneous materials were discarded.
