Correspondence, reports, lectures and research notes, educational materials, minutes, published matter, photographs, glass plate negative, slides, ephemera, artifacts, newspaper clippings, postcards, and wire sound recordings. The collection encompasses the wide range of Dodge's interests and activities. The material from 1910 through the 1920s is primarily technical and scientific including lecture and research notes, classroom materials, work on patents, and writings based on his research. From the mid-1920s the papers reflect Dodge's contributions to the teaching of physics and promotion of its significance in education and in society. Detailed topics include his work at the University of Oklahoma; the founding of the American Association of Physics Teachers (AAPT) in 1930 and the American Insitute of Physics (AIP) in 1931, the establishment of the American Physics Teacher (later the American Journal of Physics), the development of programs in engineering physics, the improvement of graduate education and college teaching, and the establishment of the University of Oklahoma Research Institute in 1941. Dodge's notes, reports and correspondence document his work on the two patents he was granted, one in 1920 for an improved rheostat, and the other in 1924 for a porous damper for acoustical instruments; his administrative work during World War II in ensuring the optimum utilization of scientists for the war effort as Director of the Office of Scientific Personnel of the National Research Council; the growth of Sigma Pi Sigma; the findings of the ASEE engineering education mission to Japan in 1951; and his trip to the U.S.S.R. in 1955 to survey Soviet scientific education. Much of the personal materials relate to Dodge's enthusiasm for camping, canoeing, and conservation. Among his correspondents were: Henry A. Barton, Alfred Bailey, Karl T. Compton, Carroll Dodge, Harold Hazen, Elmer Hutchisson, Fred Kent, Paul Klopsteg, Atwood Manley, Charles A. Plumley, Floyd Richtmyer, Duane Roller, William Schriever, Wallace Waterfall, William S. Webb, and Marsh White. Dodge's papers also include correspondence and other materials from friends Fred W. Kent and Clyde Smith, son Fletcher Dodge, mother Isabella Donaghue Dodge, and wife Margaret Wing Dodge.
