Primary source materials for the history of quantum physics in the twentieth century, collected under the auspices of the APS and the American Physical Society, with a grant from the National Science Foundation. There are transcripts of the oral history interviews, as well as the working papers of the Committee. These include correspondence with famous figures in physics, with some memoirs, photographs, lectures, etc. On microfilm (see Mss. 530.1 Ar2 ) are manuscripts of Niels Henrick David Bohr and his scientific correspondence (62 reels from the Niels Bohr Archives, Universitets Institut for Teoretisk Fysik, Copenhagen). This collection is described and analyzed in Sources for the History of Quantum Physics: An Inventory and Report, by Thomas S. Kuhn, John L. Heilbron, Paul Forman, and Lini Allen (Philadelphia, 1967). The subject guide derived from the work has subsequently been digitized in its entirety and is available through the finding aid for Mss. 530.1 Ar2 .

The interviewers' questions have been omitted from this oral history, and no editorial insertions have been made other than the brief synopsis of the donor's activities and the index.
