Collection Summary

Title: Paul A. M. Dirac Collection
Dates: 1788-1999
Extent: 190 linear feet
Repository:        Paul A. M. Dirac Library, Florida State University
Abstract: The Paul A. M. Dirac Collection consists of the personal and family papers, photographs, manuscripts, galley proofs, and published papers, scientific calculations, lecture notes, and office files of Dr. Paul A. M. Dirac, winner of the Nobel Prize (Physics, 1933). Materials relating to his professorships at St. John's College at Cambridge University where he held the Lucasian Professor of Mathematics chair from his election in 1932 until his retirement in 1969 and then as Professor of Physics at Florida State University from 1972 until his death in 1984, comprise the bulk of the Collection. A small group of audio recordings, certificates, realia, Collection administration materials, and selected published items transferred from his office at the time of his death are also included.

 

Administrative Information

The materials in the Paul A. M. Dirac Collection were donated by Professor Paul A. M. Dirac and his wife to Florida State University over a period of years from 1984 to 1997.

 

Access Restrictions

The Paul A. M. Dirac Collection, except for a small group of materials, is open for research. Until declassification of some World War II era papers occurs, they cannot be made available. A small additional collection of medical papers relating to living persons is also closed to researchers in consideration of their privacy.

 

Usage Restrictions

Duplication of materials for publication may require permission. For those items which the Florida State University does not own the literary property or copyright, it is the responsibility of the researcher to secure permission from the appropriate copyright owners.

 

Preferred Citations

Manuscripts, Photographs, and Realia: Item description, date, series number, box number, folder number, Paul A. M. Dirac Collection, Florida State University Libraries, Tallahassee, FL.

 

Processing Information

To ensure the preservation of the materials and their accessibility to researchers, nonprint materials (photographs, negatives, memorabilia, and recordings) have been removed from their original locations among the papers and collected into appropriate locations. Manuscripts, galley proofs, and published materials by P. A. M. Dirac similarly have been brought together. His office collections of reprints and books have been maintained as transferred.

Processed by: Charles Wm. Conaway, Joseph R. McElrath, Jr., Billie B. Oakes, and Burton H. Altman.

Very little of the deposited material has been removed, mainly envelopes not needed to establish dates or the identity of correspondents. Likewise journals, multiple copies of reprints, and other published materials, easily found in libraries' holdings, have been removed unless there was evidence of Dirac's use. All other items received have been retained. There is no evidence that it was Dirac's practice to keep a file of outgoing correspondence. Except for occasional notes on incoming letters to guide his assistants in replying, the content of his outgoing letters must be inferred from his actions and from subsequent incoming letters or by examining the correspondence of the recipients in other repositories. A small quantity of materials of unknown, but presumably personal, content has been retained by his widow, Margit (known as "Manci") Dirac, with the expectation that they will ultimately be donated and incorporated into the Collection.

Regrettably, much of the original order of the Collection was disrupted prior to deposit as a consequence of arriving at various times from Dirac's office, home, and elsewhere and the reintegration of a collection materials temporarily on loan to the Churchill College Archives. A trans-Atlantic relocation of the Dirac possessions from Cambridge to Tallahassee in 1972 undoubtedly had a similar effect. However, during the processing of this collection, the original order of the files was preserved as closely as possible. The general arrangement is into four major segments: the first consisting of family papers and photographs, regardless of date, and materials relating to this educational activities through his being awarded his doctorate at Cambridge in 1926. The second, and largest, segment is comprised of his "professional" papers dealing with his scientific work, lecturing, and teaching. Materials dealing with his extensive travel, membership in professional associations, and awards are also in this section. The third component contains realia, honorary certificates, and similar items. The fourth series deals with the acquisition, arrangement, and description of the Collection and subsequence analysis incidental to its organization and use, e.g., bibliographies, biographies, obituaries, memorial and building dedication materials, Project Archivist-produced genealogical charts, a perpetual calendar, etc.

 

Biographical Information

1902, Aug. 8 Born in Bristol, England to Charles Adrein Ladislas Dirac a Swiss-born French teacher and Florence Hannah Holten, a library clerk.
 
1908-1918 Attended the Bishop Road elementary school and the Merchant Venturers' Technical College (a secondary school) where his father taught. As an elderly man, he recalled that he excelled in mathematics, chemistry, and physics, but was disadvantaged by his age and size in sports activities.
 
1918-1923 He studied Electrical Engineering at the University of Bristol, with first class honors and stayed on to study mathematics, completing his examinations with first class honors after two additional years.
 
1923-1926 He was admitted to St. John's College at Cambridge, studying with Ralph A. Fowler. During this time he published several technical papers and in 1926 he was awarded his Ph.D. with a thesis: Quantum Mechanics and traveled to other European centers where modern physics was being investigated.
 
1927-1933 He progressed rapidly in his research positions being successively elected as:
  • Fellow at St. John's College of Cambridge University, 1927
  • Praelector in Mathematical Physics, 1929
  • Fellow of the Royal Society, 1930
  • Lucasian Professor of Mathematics, 1932
  • Nobel Prize for Physics in 1933 along with Edwin Schroedinger.
     
1930 He published the first edition of The Principles of Quantum Mechanics.
 
1933-1969 He continued his research activity and traveled widely, teaching and lecturing frequently in Europe, Asia, and North America, interrupted only during the time he was involved in War-related work, often taking short-term lecturing positions at major universities until his retirement from Cambridge in 1969. In 1937, he married Margit ("Manci") Wigner, the sister of Eugene P. Wigner a Hungarian colleague at Princeton's Institute for Advanced Study. He adopted her two children, Judith and Gabriel. They had two daughters: Mary Elizabeth and Florence Monica.
 
1972-1984 He accepted an appointment at Florida State University and moved to Tallahassee where he continued his active research and travel until near the end of his life on 20 October 1984. He is buried in Tallahassee.
 

 

Scope and Content

The Paul A. M. Dirac Collection covers material from the period 1788-1999, documenting his personal life and career as a student, premiere theoretical physicist, Nobel Prize winner, worker in the World War II effort, noted lecturer and world traveler, holder of the Lucasian Professor of Mathematics chair at Cambridge University from 1932 until 1969, and Research Professor at Florida State University from 1972 until his death in 1984. The collection consists of more than 190 linear feet of correspondence and other papers, manuscripts of scientific papers, calculations, books, photographs, sound recordings, framed certificates, and realia.

Series 1 -- Family Papers, Student Papers, and Photographs
The Family Papers include a few items dealing with Paul Dirac's father's family in Switzerland, but the majority deal with his parents and their families, his brother and sister, his wife and their children, and his in-laws (including his brother-in-law, Eugene P. Wigner, who also won the Nobel Prize in Physics). The Family Papers include a few examples of juvenalia, but mainly consist of materials associated with his student days at the Bishop Road primary school, the Merchant Venturers' secondary school, the University of Bristol (1918-1921), and at St. John's College at Cambridge University (from 1921 through the awarding of his doctorate in 1926). These are arranged in acid-free folders and Hollinger boxes, generally by topic and then in chronological order. About 450 photographs and reprints (and a few negatives) from all periods of Dirac's life are also included in this segment, each of them in acetate sleeves or in four presentation albums. There are few personal financial records in the Collection, here or elsewhere.

Series 2 -- Professional Papers
The Professional Papers include those non-family-related papers reflecting Paul Dirac's life as productive scholar, Nobel Prize laureate, and lecturer as the holder of the Lucasian chair at Cambridge (1932-1969) and as Professor at Florida State University (1972-1984). It includes materials associated with appointments at Princeton University's Institute for Advanced Studies (1934-1935), and War-related employment (1941-1945). It also contains materials dealing with his extensive travels and lecturing in Western Europe, the Soviet Union, the United States, Japan, China, and briefer visits to Canada, Italy, the Vatican, India, Israel, and elsewhere. His attendance at the conferences for holders of the Nobel Prize in Physics held at Lindau in Bavaria is also well documented. Dirac's topical and correspondence files are also in this section. The "subject" files have been kept intact, but the potential archival value of the context of correspondence files was lost by a previous arrangement effort and they are currently arranged chronologically. It was not his practice to keep copies of out-going correspondence, but there is a large collection of letters that he received, often with brief notes indicating the nature of his responses.

There is an extensive collection of calculations, usually in pencil and often on undated and on whatever paper was readily at hand. Dirac's publications are arranged by the dates and numbers as listed in the Dalitz bibliography (see below). The convention used is as follows: The date and number is followed by an "m" for a draft or manuscript, a "p" for a proof, and a "w" for the work as published. A "*" indicates an item not listed in Dalitz. Publications by others are arranged by their authors' names.

In addition, papers associated with his employment at Florida State University, insurance-related matters (including medical records for himself and family members), and financial matters related to his retirement and death benefits are also found here. Finally, condolences, obituaries, memorials, and items incidental to the dedication of the Paul A. M. Dirac Science Library on campus are included in this group of papers.

Series 3 -- Framed Certificates, Realia, Sound Recordings, and Office Collections of Books and Journals
A group of 22 certificates of membership, recognition, etc. have been framed in a unified style and are incorporated in this section. Realia is limited to a few items transferred from his office at the time of his death (including his desk pen set, a magnifying glass, a pillow, a framed section of a blackboard with an equation in his hand, etc.), and a bronze bust on a pedestal are among them. There is also a Japanese fan decorated and signed by Werner Heisenberg made during their visit to Japan in 1929. A small group of reel-to-reel audio tapes of Dirac lecturing and books and journals transferred from his office after his death are also included here along with a brief listing of each. Similarly, there is a list of framed photographs on permanent display elsewhere in the Dirac Library building.

Series 4 -- Materials dealing with P. A. M. Collection Arrangement and Description Project Administration
This section includes copies of the proposal to the National Science Foundation for funding the Project to arrange and describe the Paul A. M. Dirac Collection, supporting documentation and correspondence, descriptions of the provenance of the collection, donation agreements and financial appraisals, previous finding aids, biographical and bibliographic materials, etc. Additionally, some Project staff-produced genealogical charts and tables, a perpetual calendar, and similar utilitarian tools are also to be found here along with disks including the computerized Microsoft Access database and input for the on-line searchable database and text files for the creation of the Web-based finding aid.
