  • Abstract: "sporadic and limited correspondence, lecture notes, speeches, reprints, photocopies of unclassified correspondence and documents relating to the U. S. Atomic Energy commission Tolman Committee on Declassification".
  • Biographical note (archive's own account): born 4 March 1881, West Newton MA; MIT BS chemical engineering 1903; a year in Berlin; MIT PhD 1910; faculties of Michigan, Cincinnati, California (Berkeley) and Illinois before WWI; Chemical Warfare Service in WWI; associate director then director of the Fixed Nitrogen Research Laboratory 1919-1922; Caltech from 1922 (professor of physical chemistry and mathematical physics; dean of the graduate school). "Tolman became interested in relativity theory early in his career and published several key papers." WWII: vice chairman of the National Defense Research Committee (NDRC; armor and ordnance, proximity fuse, rockets); scientific adviser to General Leslie R. Groves on the Manhattan Project; US adviser to the Combined Policy Committee; chief technical adviser to the US delegation to the UN Atomic Energy Commission; chairman of the AEC Declassification Committee at his death (September 1948). National Academy of Sciences 1923.
  • Access: "open for research. Researchers must apply in writing." The folder-level list (Collection Contents) was not read this run.
  • Finding aid derived from a 1977 Word document, encoded 1999 by the American Institute of Physics (AIP) Center for History of Physics; updated 2001; last indexed 2025-12-03.
  • Google snippets (not opened): Caltech holds Tolman correspondence inside other collections: Robert F. Bacher Papers (Tolman, 1946-1948), Horace N. Gilbert Papers (1942), Robert A. Millikan Papers (1944, 1946); a "Richard C. Tolman, 1915-1921" file in Box 40 of an unnamed collection; Howard P. Robertson Papers (Robertson brought into defence work by Tolman, 1939). AIP Niels Bohr Library lists the same finding aid ("Richard C. Tolman papers, 1735-1958").

Bearing on the claims

  • Priority 1 (inventor's own work): the course lecture notes, technical notes and manuscripts are the only places where drafts of the 1917 book, Tolman's Berkeley relativity lectures (1912-1916), or his notes on the moving-body temperature (claim 4) or the lever (claim 3) could survive. Whether they do is unknown until the folder list is read.
  • Priority 4 (historical record): the record of Tolman's career does not go silent; it continues into war and government work (Chemical Warfare Service, Fixed Nitrogen Laboratory, NDRC, Manhattan Project, AEC). No "absence of evidence" anomaly for the man; the 1917 book was followed by Relativity, Thermodynamics and Cosmology (1934) [memory, high].

  • The "Richard C. Tolman, 1915-1921" Box 40 file (which collection; likely Millikan or Hale correspondence).
