The Llewellyn Hilleth Thomas Papers include research and lecture notes, class notes, personal papers, research papers (published and unpublished), some correspondence, documentation of consulting work, drafts of supervised student theses and dissertations, course outlines, examinations, memoranda, laboratory notes, symposiums, and miscellaneous papers. The bulk of this collection documents Thomas' academic teaching career, consisting of holograph and typed notes, most undated, on research for Thomas' physics lectures at Columbia University, Ohio State University, and North Carolina State University; also his student notes (2 boxes), taken at Cambridge University (England) physics lectures, 1921-1925, given by Bromwich, Eddington, Fowler, Littlewood, Pollard, and Ramsay, among others; published work (research published in journals), 1929-1982 (1 box); consulting for IBM and Timken Steel and Tube Company; symposiums, 1980-1985 (3 folders); personal papers (1 folder): professional diplomas and certificates as well as Lewis/Thomas family genealogy; and biographical information (1 folder). Topics: atomic physics, computer capacity, difference equations, electrodynamics, electron scattering, electronic structure of atoms and molecules, Fourier analysis, general dynamics, group theory, hydrodynamics, mathematics, physics, plasma (physics) quantum electrodynamics, quantum theory, quantum mechanics, relativity field theory, statistical mechanics, theoretical phy sics, among others. Correspondents: G. Bessis, Biedenharn, Dahl, Eichelberger, Grosch, Andrew Kollchoubey, Rolf Landauer, Lief, Robert Newton, among others.

Llewellyn Hilleth Thomas (1903-1992). Physicist (atomic physics, nuclear, atomic and molecular structure, astrophysics). On the physics faculty at Ohio State University (1929-1943, 1945-1946); physicist and ballistician, Ballistic Research Laboratory, Aberdeen Proving Ground, MD (1943-1945); on the physics faculty at Columbia University from 1950, member of senior staff of Watson Scientific Computing Laboratory established by IBM at Columbia; professor at North Carolina State University from 1968. Thomas is best remembered for his work on atomic physics, particularly the development of the statistical model of the atom; concurrently developed by Enrico Fermi the model is known as the Thomas-Fermi model.

Box 2
Binder Files 1921-1961, undated (MC 210 Series 3)

This series represents class notes chiefly taken while a student at Cambridge University in England. There also are lecture notes from his years at Ohio State University and a few course outlines from Columbia University. Dr. Thomas kept these notes in binders that he labeled by subject. The folder titles listed are exactly as appeared on the spine of the binder. If the label was illegible, a photocopy of the label is kept at the beginning of that folder. The folder titles appear in quotation marks in the folder by folder inventory. Dated files are arranged chronologically. Undated files are arranged alphabetically by binder title after the dated files.

Numbered Files 1935-1974, undated (MC 210 Series 4)

Dr. Thomas kept an extensive filing system for his research notes, problem-solving, and his classes. There is no key to the numbering system. Therefore, the filing system has been retained in its original order. The folder numbers are listed in the inventory, along with a brief description of the contents of each file folder. Dr. Thomas' labels for each folder appear in quotation marks in the inventory. "No label," refers to the fact that the folder was numbered, but not labeled.
