John Archibald Wheeler (1911-2008) was a leading theoretical physicist of the twentieth century, contributing particularly to the fields of general relativity, gravitation, and quantum mechanics. Wheeler was a pioneer in the study of black holes, celestial phenomena which he named. (He had a penchant for creating new terms in physics, and is credited with naming other phenomena such as geons, wormholes, and quantum foam.) Wheeler is also known for his work in atomic and nuclear physics. In 1939, he and Niels Bohr co-authored a paper that gave the basis for recognizing that Uranium 235 and Plutonium 239 are highly fissile, a milestone in the understanding of atomic energy. Wheeler believed in the importance of public service, assisting in the U.S. war effort to develop the atomic and hydrogen bombs, and served as a scientific advisor to numerous government agencies. During a prolific academic career that spanned seventy years, Wheeler taught physics to thousands of undergraduate students at Princeton University and the University of Texas, and mentored more than fifty Ph.D. students. The Wheeler Papers provide an extensive look into the expansive career of John Archibald Wheeler, the pioneering and award-winning theoretical physicist. Comprised of 150 linear feet, this large collection contains a wide array of materials including correspondence, subject files, manuscripts by Wheeler, papers by colleagues and students, research notes and notebooks, photographs, awards, and audiovisual materials. The collection provides much insight in to Wheeler's lengthy career as a scientist, scholar, and teacher. The bulk of the material is from the 1950s to the 1990s and covers the wide scope of his professional endeavors, from his teaching at Princeton University and the University of Texas, to his many publications, to his consultation work with government agencies, industry, and atomic energy projects, to his numerous public talks and lectures.

Primary source materials for the history of quantum physics in the twentieth century, collected under the auspices of the American Philosophical Society and the American Physical Society, with a grant from the National Science Foundation.

Edward Uhler Condon was a theoretical physicist at Princeton University and Westinghouse Laboratories who later served as director of the National Bureau of Standards (1945-1951), and as the director of research and development (1951-1954) and consulting physicist (1954-1974) at Corning Glass Works. The Condon Papers includes correspondence, notebooks, writings, photographs, and other materials concerning Condon's education, teaching, and his government, industrial, and academic.
