Biographical History

Edward Arthur Milne was a distinguished mathematician and one of the founders of modern theoretical astrophysics.

Milne was born in Hull, Yorkshire on 14 February 1896. He was educated at Hymers College, Hull, and Trinity College, Cambridge. He became Assistant Director of the Solar Physics Observatory, Cambridge (1920), Beyer Professor of Applied Mathematics at Manchester (1925-1928) and the first holder of the Rouse Ball Professorship at Oxford (1928-1950). Milne served in both World Wars, on ballistics and sound-ranging at the Anti-Aircraft Experimental Station at Portsmouth 1916-1918 (holding an R.N.V.R. Commission), and for the Ministry of Supply at the Ordnance Board as a 'Key Scientist' for much of the Second World War (1939-1944).

W.H. McCrea, in his memoir of Milne for the Royal Society, distinguishes three principal phases in Milne's work: atmospheric problems in astrophysics (1920-1929), stellar structure (1929-1935) and the discovery and development of kinematic relativity (from 1932). Other topics on which he wrote and lectured include thermodynamics, statistical mechanics and pulsating stars.

Milne died suddenly, in Dublin, in 1950, while preparing to give a series of lectures. These can be found in one of his last published books: Modern Cosmology and the Christian Idea of God (1952).

An annual Milne lecture was founded under the auspices of Wadham College, Oxford, the first being given in 1978.

Scope and Content

Milne died suddenly, away from home, in 1950, at the relatively early age of fifty-four. He had been twice widowed and had three still young children. In these circumstances there were more urgent tasks than the care of his papers, and the present collection, assembled after a considerable lapse of time, has many gaps. In particular, there is little record of Milne's overseas travel for research and conferences, or of his committee and editorial work. The surviving correspondence, interesting though it is, is clearly no more than a fraction of the original corpus.

The lecture notes and drafts in Sections B and C indicate the range of Milne's mathematical and astrophysical interests reasonably well, if not as fully as could be wished. Perhaps the main interest is to be found in the correspondence. The letters to his parents and brother in Section A are revealing of his personality as well as of his work as a young man in the First World War. The letters to Chandrasekhar in Section D, while mainly on technical subjects and especially Milne's growing belief in his theory of kinematic relativity, also contain many insights into his family life, bereavements, and daily struggles. There is clearly to be seen in both these sequences of correspondence Milne's deep love for Trinity College, Cambridge, whose traditions and ceremonies he accepted wholeheartedly and took part in whenever he could.

Acquisition

The collection has been assembled from several sources.

The personal letters at MS. Eng. misc. b. 423/A.6 - MS. Eng. misc. b. 423/A.20 and the note on Geoffrey Milne at MS. Eng. misc. b. 423/A.21 are the gift of Mrs. M.K. Milne, widow of Geoffrey and sister-in-law of Arthur Milne.

The correspondence at MS. Eng. misc. b. 429/D.58 - MS. Eng. misc. b. 429/D.61 is the gift of Professor and Mrs. Theodore Dunham, friends with whom Milne's daughters stayed during the Second World War.

The photocopies of letters to H. Davenport at CSAC 102.6.84/D.53A were made available by Mrs. Anne Davenport.

The remainder of the material was assembled and given by Mrs. Margaret (Meggie) Weston-Smith and Miranda Weston-Smith (daughter and grand-daughter), who were also responsible for obtaining the photocopied documents and transcripts at MS. Eng. misc. b. 427/D.2 - MS. Eng. misc. b. 429/D.50, MS. Eng. misc. b. 429/D.51 - MS. Eng. misc. b. 429/D.53, and MS. Eng. misc. b. 429/D.63 - MS. Eng. misc. b. 429/D.68.

A fuller account of Milne's career can be found in the memoir by W.H. McCrea, Obituary Notices of Fellows of the Royal Society, 7, 1950-51, pp.421-443.

A little correspondence remains in family hands.

The manuscript of Milne's Edward Cadbury Lectures, 'Modern Cosmology and the Christian Idea of God', is held in the Library of Trinity College, Cambridge (Ref.: Add. Ms. a.228). The lectures were to have been given in the University of Birmingham in 1950 but Milne died in September of that year. The manuscript was edited by G.J. Whitrow and published in 1952.

Six letters by Milne to Sir Joseph Larmor written between 1930 and 1933 are held in the Royal Society, London.

A list of additional locations of letters by and to Milne can be found at MS. Eng. misc. b. 427/D1.

Typescript with manuscript corrections and additions, in a black spring-back folder.

C   Notes and drafts


Scope and Content:

These are undated sequences for lectures and papers, some belonging to the Cambridge period and probably contemporary with the material at MS. Eng. misc. c. 870/B.5 - MS. Eng. misc. c. 872/B.7 (see especially MS. Eng. misc. c. 425/C.3) but with later additions and updatings.

The material was received grouped under the three main headings of thermodynamics, statistical mechanics and relativity and these have been retained, though it is clear from Milne's descriptive titles for some of his notes that they no longer necessarily correspond to their original state. Item MS. Eng. misc. b. 426/C.58 is a later analysis of a statistical problem posed by Milne.

Some sequences of notes are paginated by Milne, others were clipped together and have been retained in Milne's order. Sometimes he used the backs of examination scripts or class exercises for his notes, but much of the material is written on the cream-laid large quarto paper used for the 1920s lectures. Additional pages and later work are usually on smaller format paper.

C.1   Thermodynamics


Scope and Content:

Various sequences of notes and narratives, undated, the majority probably from the 1920s when Milne was working on atmospheric problems in astrophysics. The material was mainly intended for lectures and class problems but also in part for Milne's article 'Thermodynamics of the Stars' published as part of the Handbuch der Astrophysik (Berlin, 1930), or for other published work. Milne continued to lecture and publish on stellar thermodynamics throughout the 1930s, revising and updating his material accordingly. All the sequences, and the titles or opening phrases below, are Milne's.

D   Correspondence


Scope and Content:

The surviving correspondence is regrettably scanty. Attention is drawn to MS. Eng. misc. b. 427/D.1, an itemised list of letters to and from Milne now located in other manuscript collections; this was compiled, and kindly made available, by Professor K. Hufbauer, University of California, Irvine.

The extensive folders of letters to S. Chandrasekhar at MS. Eng. misc. b. 427/D.3 - MS. Eng. misc. b. 429/D.50 and MS. Eng. misc. b. 429/D.51 - MS. Eng. misc. b. 429/D.53 consist of photocopies from the originals in the Chandrasekhar archives deposited at the Joseph Regenstein Library, Chicago, and typed transcripts made by Miranda Weston-Smith. Similar photocopied material appears at MS. Eng. misc. b. 429/D.6 - MS. Eng. misc. b. 429/D.68, from originals at Churchill College, Cambridge, and at MS. Eng. misc. b. 429/D.53A.

MS. Eng. misc. b. 427/D.3 - MS. Eng. misc. b. 429/D.50 is a chronological sequence of photocopies and typed transcripts (two copies) of Milne's contribution to an extensive exchange of letters and postcards with Subrahmanyan Chandrasekhar, 1929-1950. Occasionally, letters to others occur in the sequence and this is indicated in the entries. Exceptionally, there are also letters from Chandrasekhar, at MS. Eng. misc. b. 427/D.16, MS. Eng. misc. b. 428/D.24, MS. Eng. misc. b. 428/D.43 MS. Eng. misc. b. 428/D.45, MS. Eng. misc. b. 429/D.47, and MS. Eng. misc. b. 429/D.49.

The transcripts and photocopies are not exact duplicates: see MS. Eng. misc. b. 427/D.6, MS. Eng. misc. b. 427/D.8, MS. Eng. misc. b. 427/D.21, and MS. Eng. misc. b. 428/D.23 for material occurring in one form and not the other. The transcripts often leave space for the insertion of technical terms or formulae which are of course present in the letters. There are also many errors of transcription of technical terms, proper names, and of ordinary manuscript readings.

The transcripts should always be checked against Milne's original as preserved in the photocopies.

The communications are frequent and often voluminous. The content is primarily research problems and publications or visits and lectures, generally somewhat formally expressed and dry in tone. From about 1939, with the heavy pressure on Milne of war-work, life in London, the care of his family, the loss of his second wife, brother and several old colleagues, he become less reserved and spoke more freely of his circumstances. The simple family life of the Milnes, and their joyful pleasure in the gifts (usually food) sent by Chandrasekhar, are touching, especially in contrast with the wholly abstract problems of Milne's professional life.

Most of Milne's letters are signed 'E.A. Milne'; later he relaxed to 'E. Arthur Milne' or occasionally 'Arthur Milne', and addressed his letters to 'My dear Chandrasekhar' or 'Dear Chandra' and his Christmas letters 'Dear Chandra and Lalitha'.

MS. Eng. misc. b. 429/D.51 - MS. Eng. misc. b. 429/D.51/D.53 is a separate sequence (transcripts only) of personal correspondence, principally of letters to Chandrasekhar from Margaret and Eleanor Milne, 1933-1976.
