Original collection: There is significant biographical material in the collection. There are obituaries and tributes, interviews, discussions and dialogues with Bohm, including those at Ojai, California. Bohm's ideas attracted much interest and there are a significant number of articles and papers inspired by him. Material directly recording his life and career is comparatively slight, but there are papers relating to Bohm's difficulties with the House Committee on Un-American Activities 1949-1951. These are drafts by Bohm of papers and lectures, mostly unpublished, including some drafts on quantum theory, although the bulk are of a philosophical nature. There are also copies of a few of his published works; book reviews by others of Bohm's works; and drafts by F. D. Peat drawing on Bohms work, which were found with the papers. The correspondence is divided into two sequences. There is a sequence of general correspondence, including photocopies of correspondence with Einstein circa 1950-1954 which includes discussion of quantum theory as well as Einstein's advice on Bohm's career. Other significant correspondents are R. Karnette, H. M. Loewy and M. Phillips. The second sequence is photocopies of the voluminous correspondence on a wide range of philosophical and scientific subjects with the American artist and theorist Charles J. Biederman, 1960-1969.

Supplementary material: includes more biographical material; some personal correspondence; drafts, publications and lectures, which forms the largest component of this addition, including lectures On plasma physics, delivered at the University of Rome in May 1958 and on General theory of collective coordinates, University of Bristol; professional correspondence with the philosopher J.G. Bennett, A. Kahler, D.L. Schindler, F. Wilhelm, Miriam Yevick. Topics include wholeness and fragmentation and the implicate order; Bohm's difficulties with the Un-American Activities Committee and his move to Brazil; and the development of his ideas in quantum theory.
