Biographical / Historical

Paul Dirac was born 8 August 1902. In 1923 he went to Cambridge University as a mathematics research student under the theoretical physicist Ralph Fowler. Dirac then did graduate work in statistical physics and quantum theory. He completed his PhD degree at Cambridge in 1926. In 1926 he went to stay at Bohr's Institute in Copenhagen and continued his work. In 1927 he published ‘The Quantum Theory of the Emission and Absorption of Radiation’. From 1927 onwards Dirac lectured on quantum mechanics at Cambridge and in 1930 he published the textbook 'The Principles of Quantum Mechanics'. He was elected a fellow of the Royal Society in 1930 and Lucasian Professor of Mathematics at Cambridge University in 1932. He received (jointly) the Nobel Prize for his wave equation of the electron in 1933. Dirac married Margit Balazs in 1937. She had a son and a daughter from her previous marriage and they then had two daughters. After he retired in 1969 he went to the University of Miami and in 1971 took up a research professorship at Florida State University, Tallahassee. Dirac died there 20 October 1984.

Immediate Source of Acquisition

Dirac loaned his early papers while he was still Lucasian Professor of Mathematics at the University of Cambridge, in 1969, having already deposited the proof copy of Heisenberg's first paper on quantum mechanics earlier that same year. The rest of the collection came to the Archives Centre in September 1971. Dirac's widow removed the papers in 1987 to join the rest of his papers at the Florida State University, Tallahassee, USA. DRAC 4/1 was deposited by Dirac's daughter in 2013.

Existence and Location of Originals

The originals of these xeroxes are held at the Dirac Library in the USA:


This collection (fonds) level description was prepared by Louise King of Churchill Archives Centre in December 2004. Biographical information was obtained from Professor Dirac's entry in the Oxford Dictionary of National Biography (2004) and from the catalogue of the papers made in 1981. The catalogue was converted from typescript into electronic form by Lynsey Robertson in 2009. DRAC 4/1 was added to the catalogue by Madelin Terrazas in August 2013.
