Jodrell Bank Observatory Archive

Archive Collection

Scope and Content

Papers relating to the Jodrell Bank Observatory, Jodrell Bank, Cheshire.

The collection is a hybrid, consisting primarily of the operational and administrative records of the Observatory, records of the University of Manchester (sub) department of radio-astronomy, and the personal papers of Sir Bernard Lovell, Professor of Radio Astronomy and Director of Jodrell Bank, 1951-1980. The distinctions between these component parts are not always easily identifiable.

The archive is extensive and comprises files of correspondence, telexes, papers relating to the funding, construction and operation of the telescope, research programmes and projects, the use of computing at the Observatory, accounting records, scientific reports, telescope log-books, research notebooks and copies of papers and articles published by Lovell and other JBO staff. There is correspondence with international organizations, national funding bodies and research institutes, and individual scientists in Britain, the United States and the Soviet Union.

Probably the most significant part of the archive for the Observatory's research work and radio-astronomy in general are correspondence files, arranged in nine series (JBA/CS1-9), comprising several hundred files. Most of the correspondence files relate to Lovell's research work and his papers as Director (JBA/CS6 comprises Lovell's more personal files); series JBA/CS8 and CS9 consist of the correspondence files of Lovell's colleague Robert Hanbury Brown, professor of radio-astronomy at the University of Manchester 1960-1963. Correspondence and papers of other significant figures at Jodrell Bank, namely J. G. Davies (JBA/DAV), H P Palmer (JBA/PAL), Conrad Slater (JBA/SLA) and Francis Graham Smith (JBA/SMI) are filed in separate series.

The CS files also include much information on early research activities at Jodrell Bank, and include correspondence between Lovell and leading physicists and astronomers including: Edward Appleton, Patrick Blackett, Bart Bok, Thomas Cowling, Philip Dee, M. A. Ellison, Erwin Findlay-Freundlich, Nicolai Herlofson, J.S. Hey, Cuno Hoffmeister, Vladimir Kourganoff, Bertil Lindblad, Gordon Little, Rudolph Minkowski, Jan Oort, Ernst Opik, J. L. Pawsey, J. P. M. Prentice, J. A. Ratcliffe, Svein Rosseland, Martin Ryle, Dudley Saward, Harlow Shapley, Sydney van den Bergh, and Frederick Whipple (correspondence with Blackett and Ryle being particularly extensive).

There is extensive information on the general running of the Observatory, including personnel, buildings, maintenance, allocation of frequencies, the concourse centre and the Jodrell Bank Tree Society (arboretum). There is also much relations with the University of Manchester, government departments and agencies (DSIR, Science Research Council), equipment suppliers and contractors (particularly Husband & Co.), private funding bodies, the media, and with the local community. Also covered are the Mark II and Mark III telescopes, and the various JBO outstations. There are numerous files on scientific and astronomical agencies with which the Observatory and its staff were associated: Royal Astronomical Society, International Astronomical Union, International Union for Radio Science (URSI), CSIRO, the Solvay Congress, British Association, NASA plus specific projects and activities such as Halley Bay, meteor experiments, tracking of space probes and satellites (including the Sputniks), Venus Experiment, Project West Ford, NASA's STL project, Echo II, scintillations, and research on pulsars and quasars. Lovell's correspondence also includes a large number of letters forms members of the general public concerning astronomical phenomena, including sightings of alleged unidentified flying objects (Lovell often categorised these letters as 'odd' or 'very odd').

The series on the Aeronautical Research Council (JBA/ARC), British Space Development Company (JBA/BSD), Committee on Space Research (JBA/COS), International Geophysical Year (JBA/IGY), Meetings and Records (2 series) and Royal Society document the involvement of Jodrell Bank staff, primarily Lovell, with external bodies, some relating to specific projects. JBA/MKV contains extensive information on the aborted MKV telescope project. JBA/PUB consist of publications of Jodrell Bank staff, while JBA/SYM deals with a range of academic symposia and conferences held at the Observatory. JBA/COM is a district series which deals with computing issues at the Observatory (Jodrell Bank was a pioneer in the use of computing in astronomy), and JBA/REC is a miscellaneous series of records produced by the Observatory, including meteorological records.

The archive includes Lovell's papers which are directly related to his work as Director of the Radio-Telescope, as well as papers which relate to his other academic and outside interests. In the latter category are the series JBA/PRE which deal with his student and early career papers, and the papers relating to his membership of the Worshipful College of Musicians (JBA/WCM). The archives also include Lovell's (appointment) diaries (JBA/DIA) and papers relating to his lectures (JBA/LEC)

The archive constitutes an essential source for the history of radio astronomy and science in general, particularly in post-war Britain. It includes essential information about international co-operation in astronomy, the development of diverse research programmes in British radio-astronomy, the funding and organization of scientific research and higher education, the presentation of the Jodrell Bank telescope as a iconic development in post-war British science among many other topics.

Administrative / Biographical History

The Jodrell Bank Observatory is one of the world's largest radio-telescope facilities. Originally known as the Jodrell Bank Experimental Station, it was renamed the Nuffield Radio Astronomy Laboratories in 1966, and changed to its current name in 1999.

The first radar transmitter and receiver was installed by Bernard Lovell, then working as a physicist at the University of Manchester, at Jodrell Bank, Cheshire, in December 1945 (the University campus had proved unsuitable because of the high level of electrical interference). At this period Lovell was researching cosmic rays under the direction of Patrick Blackett, professor of physics at the University of Manchester. Lovell's work involved studying radio echoes from large cosmic ray showers in the Earth's atmosphere, using old military radars. As a result of this, Lovell went on to make important discoveries in meteoric astronomy.

By the late 1940s, radio-astronomy was becoming an established area of research. The University of Manchester was keen to develop research in this area, with a team led by Lovell. In 1947, a new 218ft transit telescope was built to study radio emissions from space. However, this telescope could only track a limited area of the sky. Lovell wanted to build a fully steerable telescope, but it proved difficult to find an engineering firm which felt it could meet the specification. In 1949, the University opened discussions with Messrs. Husband & Co of Sheffield. Husband drew up plans for a 250ft fully steerable telescope, and in 1951 an application for £259,000 grant was submitted by the University to the Department of Scientific and Industrial Research, the sponsoring government department. The construction of this telescope proved to be long and complex, as costs mounted and redesigns were required. As completed, the telescope comprised a 250ft paraboloid, constructed of steel sheets and supported by a steel framework. At the centre of it bowl was a 62.5ft steel mast. The bowl was attached to two towers by a set of trunnion bearings, with the towers mounted on six bogeys which ran on two concentric circular rails along the ground. These allowed the telescope to be turned horizontally or in azimuth. Originally known as the Mark 1, the telescope became operational in 1957. At the time the Mark 1 was the largest fully-steerable radio telescope in the world.

The telescope was at the time one of the most powerful radars in the world, and soon attracted public attention when it tracked the Soviet Sputnik satellite in October 1957. During the 'Space Race' the telescope was frequently used to track satellites, missiles and space probes; work which proved to be financially beneficial.

The construction of the telescope had left significant debts and some of these were paid off by the industrialist Lord Nuffield. In recognition, the Jodrell Bank facility was renamed the Nuffield Radio Astronomy Laboratories in 1966. In 1970 some major modifications were made to the telescope, which was renamed the Mark 1A. In July 1987 it was renamed the Lovell Telescope. Between 2000-2002, there was a further major upgrade to this telescope. In 1964 the Mark II telescope was completed at Jodrell Bank; this was a smaller telescope used for short centimetre wavelength research. Telescopes were set up at other locations, including a 25m telescope at Defford, Worcestershire, and the Mark III telescope constructed at Wardle, south Cheshire in 1966 (decommissioned in 1996). Plans for other telescopes, the Mark IV, Mark V and the Mark VA, were aborted.

Jodrell Bank Observatory has undertaken a wide range of research since foundation. Some of its earliest work involved radar observations of meteors and planets, and the measurement of the Moon's surface. In the late 1950s, important work was done on quasars, which used portable telescopes transmitting by microwave radio links. Later research focussed in studies of the radio energy of neutral hydrogen; radio astronomical detection of interstellar molecules; radio recombination lines; pulsars and flare stars. Since the 1960s the Observatory has been involved in Very Long Baseline Interferometry research, which uses multiple radio-telescopes to collect data from radio-astronomy, and is an important part of the European VLBI network.

Since the 1970s, some of the most important work undertaken by the Observatory has been the MERLIN project. This built on existing work in long baselines, using the Mark II and Mark III telescopes as part of an interferometer. With additional telescopes added, more information could be collected on radio sources, as observations were possible of fringe visibility variations as the baseline of the interferometer changed during the observation. Originally known as Multi Telescope Radio Linked Interferometer project (MTRLI), it is now known as MERLIN (Multi-Element Radio Linked Interferometer]. MERLIN involved a network of radio telescopes including outstations at Knockin (Shropshire), Defford (Worcs.), and Darnhall, Wardle and Pickmere (formerly known as Tabley) in Cheshire. In the late 1980s a radio-telescope of the University of Cambridge joined the network. In recent years the Observatory has been involved in the e-MERLIN project to upgrade the MERLIN array.

Bernard Lovell was born at Oldland Common, Gloucestershire on 31 August 1913. He was educated at Kingswood Grammar School, Bristol, and the University of Bristol. After completing a doctorate on the conductivity of thin metallic films at Bristol, he took up the post of assistant lecturer in the department of physics of the University of Manchester in 1936.

During the Second World War, Lovell worked at the Telecommunications Research Establishment on radar, particularly the development of 'blind bombing' systems. He was appointed OBE for this work. After the War, he returned to Manchester to work on cosmic radiation under Patrick Blackett. He was promoted to senior lecturer in 1947, reader in 1949 and became professor of radio-astronomy (a new post in 1951). He retired in 1980.

Lovell was a very prominent public scientist in the middle decades of the 20th century, He delivered the Reith Lectures in 1958 (published as The individual and the universe (1959). Lovell wrote a number of books on radio-astronomy and cosmology, as well as an autobiography Astronomer by chance (1990). He was elected FRS in 1955 and awarded the Royal Medal in 1960. Lovell was president of the Royal Astronomical Society from 1969-1971, and of the British Association in 1975-6. He received the RAS's Gold Medal in 1981. He was knighted in 1961.Outside of his work, Lovell pursued his interests in music, cricket and arboriculture. Sir Bernard Lovell died on 6 August 2012.

The archive was originally arranged and described in the 1990s. No documentation survives of the method of cataloguing adopted. The current catalogue is essentially a new edition of this catalogue, compiled in line with current archival descriptive standards.

Current arrangement and description of the archive is provisional, and further processing will be required in future. Currently, the collection is not arranged in archival order, and in some cases, the particular provenance of parts of the archive is not indicated. It also appears that files have not been rearranged in chronological order withins series, but were listed as found. The archive will be recatalogued, including some currently uncatalogued material, with clearer explanations of content.

Some personal papers of Sir Bernard Lovell are not yet catalogued, and hence are not described in this catalogue.
