A small collection of papers of Sir Arthur George Tansley, mainly related to the formation of organisations, in the period 1918-1921, that aimed to promote pure and applied scientific research. The bulk of the collection consists of papers relating to Tansley's involvement in the Scientific Research Association. The Scientific Research Association's papers include rules, promotional leaflets and circulars, financial material and a relatively large amount of correspondence. A smaller amount of material survives for the National Union of Scientific Workers including rule booklets, membership lists, reports from meetings, agenda and promotional leaflets and circulars. Only a few items are preserved in this collection for the Federation of Technical and Scientific Associations and the Cambridge Research Group. The published articles and reports at AT/5 mainly concern issues related to the funding, support and the general state of scientific research. As a whole the collection reveals many problems faced by those who wished to organise research work after the first world war, such as the problem of rival organisations created to promote research whose aims overlapped, and disagreements over how and whether research could be organised. For example a letter from the Royal Society to the Scientific Research Association commented that 'lines of development' were 'discovered not by councils or committees but by the instinct of individuals, and the less this is trammelled by organization the better' (AT/2/6/1/42). The article 'Research and Organisation' at AT/2/3/15 was written in an attempt to answer such criticisms by arguing that research could be organised. Other issues also surface in the correspondence of the Scientific Research Association. For example one letter opposed support for any scheme founded on government funding as 'government endowment will, in the long run, corrupt Science...' (AT/2/6/2/17). There were also disagreements as to whether emphasis should be laid upon 'the promotion of scientific research' or 'the economic interest' of research workers which seems to have contributed to a division between the National Union of Scientific Workers and the Scientific Research Association (AT/2/4/3).

The papers are extensive, relating to almost every aspect of Blackett's career in science and public life. There is biographical and personal material including large numbers of letters of congratulation received on the occasion of the various scientific and public awards and honours with which Blackett's achievements were recognised. There are records of his work on particle disintegration, cosmic rays, astrophysics and magnetism in the form of laboratory notebooks, working papers, correspondence, lectures, publications and broadcasts. There is documentation of his activities on various defence projects and as a member of government committees before, during and after the Second World War. Blackett's political interests are represented by material relating to the Association of Scientific Workers, Labour Party discussion groups on science and technology policy and the Ministry of Technology instituted after the Party's 1964 electoral victory. There are records of a wide range of science-related interests such as the history of science and technology, science, education and government, and nuclear weapons and disarmament, and of his overseas activities including material relating specifically to India and that concerned with matters more generally affecting developing countries.

A few lacunae in the surviving material have been identified. There are no documents relative to Blackett's service with the National Research and Development Corporation or the Department of Scientific and Industrial Research and, of his correspondence during the Second World War, only that for 1942 survives.

The correspondence, papers and diaries of Sir Charles Blagden. Blagden's papers are interesting on several levels, generally for his close contact with European men of learning, and his relationship with Sir Joseph Banks. Blagden's professional researches are represented by medical notes in the boxed sequence. These are grouped with papers on other subject interests, including linguistics, e.g. a draft Tahitian-English dictionary, compiled from conversations with Omai, whom Blagden inoculated after Omai's voyage to England with James Cook. Blagden's interest in antiquities and travel is documented by diary entries, as is his intercourse with fellow scientists, particularly those associated with the founding of the Royal Institution.

Working papers and correspondence of Sir Francis (Franz) Eugene Simon. Scientific notebooks in the collection date from 1919-1934, largely the period of Simon's researches on low temperature physics at the Physikalisch-Chemisches Institut of Berlin University, and subsequently at Breslau. Other notes and manuscripts for lectures and articles are post 1930, while a large group of correspondence files are from the years 1922-1956, providing a full account of Simon's dealings with many fellow scientists and scientific organisations. Individual letter files concern V.M. Goldsmidt, Max Born, Gwyn Owain Jones and Nevill Mott among many other notable figures. Details of Simon's involvement in atomic energy development are to be found in papers on uranium isotope separation (MAUD Committee notes) and UK Atomic Energy Authority correspondence. Simon's professional appointments as head of the Clarendon Laboratory and as science correspondent to the Financial Times are represented by substantial groups of letters. There are twelve notebooks with some associated papers; the series also includes files of lectures, articles, cuttings and souvenirs, including photographs, with files of correspondence. Two later additions to the collection consist of correspondence and files highlighting Simon's contacts with industrial firms, universities and international organisations.

Extensive papers of Howard Walter Florey, Baron Florey, relating to almost every aspect of his career in science and public life. The scientific materials include a complete run of laboratory notebooks, 1924-1968, files on the work for which Florey is best known, penicillin and antibiotics, 1940-1962, together with papers, research notes and photographs on mucus secretion, traumatic shock and electron microscopy. Florey's writings are preserved in the form of drafts and proofs of published items, together with relevant correspondence. His correspondence indicates the depth of his involvement in the affairs of particular organisations, notably the Oxford University School of Pathology and the Royal Society. The work of Ethel Florey (née Hayter) and Margaret Augusta Florey (née Fremantle) is also present.

Letters of Nevil Maskelyne on astronomy.

Letters from Sir Robert Moray to his friend Alexander Bruce, Earl of Kincardine, also known as 'The Kincardine Papers'. Bruce was sick of the ague in Bremen for part of this time, and the letters were written to alleviate the tedium of of Bruce's illness, hence ranging over topics which might not otherwise have been the subjects of correspondence. They include accounts of chemical experiments in his laboratory, his interest in magnetism, medicine in all its aspects, horticulture, fuel, whale fishing, its risks and profits, coal mining, water wheels and tide mills, stone quarrying and the various qualities of different stones, the pumping works needed for undersea coal mines at Bruce's home at Culross in Fifeshire, even to the trees whose wood was best for pipelines, and the diameter of the bore best suited to the purpose. Familiarity is shown with mathematical and surveying instruments, with music, and all sorts of mechanical devices and especially clocks and watches, more particularly the taking out of a patent in respect of a clock for use at sea for finding longitude. Bruce is advised on the choice of books over a wide range of subjects. Moray includes anecdotes to amuse his ailing correspondent; he describes his quiet life and is enthusiastic about many of his chemical experiments. Notable at the end of the letters Moray added what he described as his Masonic signature - a pentagram which also occurs in his crest.

The vast majority of the material relates to Dent's research and clinical interests and falls into four main categories: correspondence files; files created around the publication of papers; lecture notes and symposium papers; and case/research notes. There are also smaller quantities dealing with other aspects of his career, such as the administration of UCH Metabolic Ward. The papers thus reflect most of Dent's scientific and clinical interests. This research is mainly represented by the abstracted documentation which he kept with drafts of his published papers (see section E.1) and also by correspondence about cases and clinical case notes (see section C.5). To a lesser degree they also illustrate the work at the laboratory bench which underpinned much of this research. For example, a file of unidentified paper chromatograms has been preserved (C.2/10) to illustrate one of Dent's methods of working, as described by his colleague, Heathcote, and quoted in the Biographical Memoirs of Fellows of the Royal Society, 1978: 'Paper chromatograms were not to be thrown away. They were filed and, since the colours faded, the outline of each spot was drawn in and the intensity of the colour was indicated by a number.' The way in which Dent compiled a large series of files around drafts of scientific papers also illustrates the importance of the published paper to him as a stage in the research process. An incomplete collection of reprints of Dent's published papers may be found in section E.2 of the collection.
