Blackett CSAC 63/1/79 6 GENERAL INTRODUCTION TO THE COLLECTION PROVENANCE The material was assembled from various sources: from Blackett's flat in London and his house in Wales, via Lady Blackett; from his room at Imperial College, London, via the Royal Society and Professor H. Elliot. Lady Blackett currently retains Blackett's diaries of his service in the Navy 1914-16 (see A.11), four bound volumes of press-cuttings, photographs and other family documents. CONTENT The collection is extensive, relating to almost every aspect of Blackett's long and varied career in science and in public life. Blackett himself frequently used the material for lectures and writings on matters of particular personal or historical interest such as his period of research at the Cavendish Laboratory, Cambridge, under Rutherford, operational research and other controversies in the second world war, aspects of India's development, and the like. Furthermore, it is apparent that, towards the end ofhis life, he was assembling material for one or perhaps two books: a collection of writings and an autobiography.” The clearest statement of his intentions is in a letter to M.M. Gowing dated 22 May 1972, in which he says: '... | am considering the possibility of publishing a volume of my collective papers, essays, lectures, etc.' (see D. 183); in November 1973 he writes in similar vein to the Director, National Maritime Museum: 'I am writing up a good deal about my activities during the war ...' (see D.58); the note in H.123 would also seem to be part of a draft introduction to such a work. With this in view, Blackett obtained published or typed copies of the writings chosen for inclusion, revised and emended them, and sometimes added new linking material. Documents of this kind can be found in D.58, D.110, D.183 (quoted in part above) G.23-G.31, G.72, G.84 H.1, H.64, H.77, H.96, H.109, H.110, H.119, H.124. It will be seen that none of these refers to any of Blackett's 'scientific' work in the narrow sense. * See ADDENDUM on p.11. P.M.S. Blackett CSAC 63/1/79 7 As a result of these activities, and of the multiple provenance, the collection when received was in doubtful order. Although most of the folders bore Blackett's own note of the contents, this was not always a reliable guide, as he often 'cannibalised' previous work when preparing a lecture or paper, removing earlier work to a new folder or adding later material to the originals. While every attempt has been madeto retain Blackett's preferred order in so far as it can be discerned, his headings and descriptions being preserved and indicated by inverted commas in the catalogue entries, some re-organisation was undertaken to bring the material under the broad headings of the List of Contents. The introductory notes to the Sections and sub-sections of the catalogue indicate the main areas of interest in the collection. References to the ‘Tizard Committee’ and the 'Tizard-Cherwell controversy’ are listed under Tizard in the Index of Correspondents; similarly, material on Rutherford (see esp. H.80), E.J. Williams, Nehru and others, can be located from the Index. Various episodes in Blackett's career can be clarified, or more accurately dated, from the manuscripts, and are briefly noted here in chronological order. Fuller accounts appear in the catalogue entries. J.35, correspondence with A.V. Hill on the date of Blackett's appointment as Scientific Adviser to General Sir Frederick Pile, A.A. Command; D.84, Blackett's paper, ‘Scientists at the operational level’, leading to his appointment as Chief Adviser Operational Research, later Director, Naval Operational Research; D.174, J.3, correspondence with C.R. Attlee and others on Blackett's paper on the international control of atomic energy; B.48, correspondence with C.D. Anderson on the discovery and naming of V-particles; E.24, E.33, papers and correspondence on the 'Gaitskell Group! of Labour Party advisers. P.M.S. Blackett CSAC 63/1/79 8 There are also the text of, or material relating to a substantial numberof publications by Blackett omitted from the Bibliography accompanying the Memoir by A.C.B. Lovell (Biographical Memoirs of Fellows of the Royal Society, 21, 1975, 1-115, also available as a separate publication). They are listed here in catalogue sequence. B.115, B.116, B.120 C.197-C.199 D.104, D.108 F.19-F.21, F.30, F.58, F.63, F.72-F.74 G.4 (lackett's report on the organisation of the armed forces of India), G.66, G.71, G.110 H.8, H.45, H.74, H.77, H.105, H.122, H.132, H.136, H.137, H.139 J.6, J.116 There are in addition many unpublished writings throughout the collection. For all the wealth of material in certain areas, there are lacunae elsewhere. No documents survive, for example, relative to Blackett's long service with the National Research and Development Corporation 1949-64, or the Department of Scientific and Industrial Research 1955-60; and, of his correspondence in the war years, only that for 1942 survives (D.126 - D.147). Blackett always had a fondness for acronyms and abbreviations, and this grew stronger with age; some ofhis later notes and drafts bristle with clusters of initials which, in conjunction with his increasingly cramped hand andhis habit of paginating by beginning with Roman | (on a page often later removed) and con- tinuing in Arabic numbers 2...n, make them difficult to follow or attribute with confidence. Conversely, one can only admire his determination to maintain a presence in the world of scientific research despite great pressures of public life, and, later, of failing powers; the documents and correspondenceonhis last research (C.182 - C.185) conveythis especially clearly. P.M.S. Blackett CSAC 63/1/79 PRESENTATION 9 The material in Sections A - H is presented chronologically within the sub-sections designated in the list of contents. Section J. Correspondence, is in alphabetical order. Many of the Sections and sub-sections include a brief introductory note summarising their contents and drawing attention to material of particular interest. Scientific research notes and data Blackett's scientific fame rests in part on the versatility of mind which enabled him to make significant contributions to knowledge in several areas of research (particle disintegration, magnetic spin, rock magnetism) as well as to develop the technique of operational research. Nevertheless, these contributions emerged from a gradual evolution in Blackett's thinking, and there is no sharp switch from one to another even when there is a discontinuity in time (such as the long period of war service) or place (such as the various moves from Cambridge to Birkbeck, Manchester and Imperial College). The distinction between Sections B and is therefore to some extent an artificial one, and cases of overlapping material are noted in the entries. Almost all the material was received in Blackett's own folders, usually with his note of the contents in some abbreviated form, e.g., 'C.R.' (= Cosmic Rays), 'R.M.' (© Rock Magnetism). The contents of the folders may be any or all of the following: laboratory experiments, datasheets, graphs and calculations; notes, drafts and comments for talks or publications; Blackett's or others’ off- prints, sometimes annotated; correspondence. Bulky folders have beensplit into more manageable units, but kept together with a note of their original grouping. Blackett's titles and descriptions of the folders are given in inverted commas. Blackett kept various sequencesof his notes clipped or pinned together. These sequences have beenretained in his order, although the pagination, size of paper, etc. are often heterogeneous. Manyof Blackett's own notes were made on the backs of previous notes, drafts, proofs, etc. No attempt has been made to give an account of such material. P.M.S. Blackett CSAC 63/1/79 Lectures and publications 10 Manuscript notes, typed drafts or offprints of Blackett's extensive output of lectures and writings are to be found throughout the collection. Those on specific research topics were kept by him with the data in Sections B and C and have beenleft there; similarly with material on operational research in Section D and on India in Section G. Section F groups together talks on three topics arising from Blackett's involvement in public life, and Section H contains the sequence of all other surviving documents of this type, including his Anniversary Addresses as President of the Royal Society and his speeches in the House of Lords. Correspondence Correspondence dealing with a specific research topic, lecture or publication was usually kept by Blackett in the same folder as his notes and drafts on the subject. Such material has been left in place wheneverpossible, or, if it has been re-allocated, a note has been madeto that effect. The corres- pondence on magnetic spin (C.41 - C.71) and on rock magnetism (C.221 - C.268) is in chronological order and enables Blackett's thinking, his methods, and the graph of his activity to be clearly seen. The surviving correspondence on cosmic rays (B. 132 - B.147) is, though interesting, regrettably much less complete. There is very little material remaining from the war years. Correspondence on overseas activities (G.32 - G.51, G.82 - G.84) and general correspondence in Section J are in alphabetical order, with dates and an indication of any material of personal or scientific interest; a note is also made of cases when only Blackett's carbon copy survives. py y The index on pp.361-401 includes correspondents from whom letters survive, with cross-references to any other material relating to the individual concerned. P.M.S. Blackett CSAC 63/1/79 Conspectus 1 Pp.348-355 contain a Conspectus of Blackett's publications as listed in the Bibliography of Lovell, Memoir, and the principal items in the collection to which they refer. There is anote onp. 8 above of several publications omitted from this Bibliography, and there are many unpublished items. A photo- copy of the Bibliography is included by permission on pp. 356-360. References Material in every Section is linked as far as possible to A.C.B. Lovell, Biographical Memoirs of Fellows of the Royal Society, 21, 1975, 1-115, of which a copy is included in A.1. References to the text are in the form Lovell, Memoir, p ... References to the Bibliography are in the form RS ... ACKNOWLEDGEMENTS Weare very pleased to acknowledge the invaluable work of Professor H. Elliot and Dr. J.P. Astbury in identifying for the Conspectus of Publications the manuscripts and correspondence in Section B. We are grateful for the advice given by Dr. W.S.C. Williams on cosmic rays, and by Professor E.A. Vincent on rock magnetism. Our thanks are also due to Mrs. M.M. Edwards for careful and accurate typing, and her patience with successive drafts and revisions of the catalogue. ADDENDUM Whenthis catalogue was in proof, Lady Blackett contributed some additional material, including plans and extracts from her husband's autobiography. These documents appear on p.13 as A.10A.

P.M.S. Blackett CSAC 63/1/79 32 SECTION B_ PARTICLE DISINTEGRATION, COSMIC RAYS, ASTROPHYSICS B.1 - B.145 The material in this Section documents the first steps in Blackett's scientific career - his work at the Cavendish Laboratory under Rutherford, his year in Géttingen with Franck, his move to Birkbeck College, London, in 1933 to head his own department, and then to Manchester to occupy the Langworthy Chair of Physics. He photographed the disintegration of the hydrogen nucleus (1924), collaborated with Occhialini to provide evidence for the existence of the positive electron (1933) and supported the research of Rochester and Butler which led to the discovery of the V-particles (1947). Not all of the evidence has survived - whether in the form of laboratory notebooks, working papers or correspondence - but those documents which remain testify to Blackett's energy, persistence and deft experimental technique. Section A should be consulted for several items of interest pertaining to Blackett's work on particle disintegration and cosmic rays - see especially his application to the Royal Society for a Moseley Fellowship (A.12), press-cuttings relating to the electro-magnet built by Metropolitan-Vickers for Blackett and installed in the Magnet Hut at Birkbeck (A.15), letters of congratulation on the award of the Nobel Prize, many of which recall Blackett's work which led to the award, and of course the obituary notices and tributes published after his death. P.M.S. Blackett CSAC 63/1/79 33 Section B - Particle disintegration, Cosmic Rays, Astrophysics The material is presented as follows: B.1 - B.21 Laboratory notebooks on particle disintegration, 1920-32 With an introductory note B.22 - B.61 Working notes and papers on particle disintegration and cosmic rays, 1923-56 With an introductory note B.62 - B.67 Photographs of particle disintegration and cosmic rays B.68 - B.74 Working notes on theories of the origin of cosmic rays, 1949-55 B.75 - 8.83 Working notes on astrophysics, 1953-59 B.84 - B.13]1 Lectures, broadcasts, publications, 1932-60 With an introductory note B.132- B.147 Correspondence, 1923-74 With an introductory note Because Blackett's research evolved from one topic to another, interest in each being aroused and developed by previous work, the above categories are not rigidly defined and are intended to provide only a rough guide to contents. Even if it were possible to distinguish areas of interest morestrictly, Blackett's record-keeping would make inevitable some degree of overlap, since he often intermingled various types of document to suit his purposes, e.g. pages were torn from laboratory notebooks and kept with the working papers, photographs and notes for lectures were inserted in notebooks, etc. Wherever possible, the presence of ‘anomalous! material of this kind is indicated in the entries below.

Blackett CSAC 63/1/79 34 Section B - Particle disintegration, Cosmic Rays, Astrophysics B.1-B.21 LABORATORY NOTEBOOKS1920-32 The notebooks are presented in chronological order as far as possible. They are all in Blackett's hand, unless otherwise indicated; other hands are identified where known. The notebooks provide a record of Blackett's first research at the Cavendish Laboratory under Rutherford (B.2 - B.4), his year at Géttingen with Franck (B.10 - B.12) and his collaborative work with research students E.P. Hudson (B.13), F.C. Champion (B.17 - B.18) and D.S. Lees (B.15, B.19 - B.20) in Cambridge. Several incomplete sequences (B.5 - B.6, B.17 - B.18) indicate that some notebooks have not survived.

An attempt has been madein the list below to present them in chrono- logical order, but since many of the folders contain a wide range of material of differing dates, this ordering is of necessity somewhat artificial and incomplete. Some originally very bulky folders have been split into several smaller folders for ease of reference, e.g. B.22 - B.25, B.35 - B.37; in some cases, manu- scripts and drafts for lectures have been removed and listed sepaarately (see the introductory note to B.84 - B.131). Some of the papers refer to measurements and observations recorded in laboratory notebooks. It has not been practicable to cross-reference such cases to the notebooks listed above (B.1 - B.21), since many of Blackett's notes refer to books which are missing from the sequence. Some of the notes are written on the verso of examination scripts, others are on specially devised forms for the recording of data. and in Blackett's hand unless otherwise indicated; other hands are identified where All| notes are manuscript, known.
