PROVENANCE

The papers were received from Dr Marion Hanbury Brown, daughter of Robert Hanbury Brown, in August 2003 and August 2006.

OUTLINE OF THE CAREER OF ROBERT HANBURY BROWN

Robert Hanbury Brown was born on 31 August 1916 in Aruvankadu, South India, where his father was in charge of a cordite factory. He was sent to England to be educated and attended Cottesmore Preparatory School in Hove, Sussex, from the age of eight to fourteen. In 1930 he entered Tonbridge School in Kent, switching to Brighton Technical College after only two years. The decision was partly the product of strained family finances – his parents had divorced when he was about nine and in 1932 his stepfather disappeared in a cloud of debt – but Hanbury Brown had long shown an active interest in technological matters. His grandfather (the irrigation engineer Sir Robert Hanbury Brown) was one of the early pioneers of radio, and his legal guardian after his parents’ divorce was a consulting radio engineer. Hanbury Brown remembered his childhood as a happy time spent ‘always making radio sets or building something’ (Interview with R. Bhathal, 10 February 1995. See A.30).

At Brighton Technical College he studied for an external degree in the University of London, graduating B.Sc. with first class honours in electrical engineering at the age of nineteen. At this time appeared also his first publication (with his student friend Vic Tyler), on ‘Lamp polar curves on the cathode-ray oscillograph’. With a grant from East Sussex County Council he then embarked on a postgraduate course in advanced studies on telegraphy and telephony at City & Guilds of London Institute, then part of Imperial College. At the time he hoped to complete a doctorate in radio engineering and to pursue a career that would combine his interest in radio with flying, for which he had developed a yen.

Hanbury Brown’s involvement both with the new University of London Air Squadron and with cathode-ray tubes drew the interest of the Rector of Imperial College, Henry Tizard. Tizard chaired a committee that had recently been set up by the Air Ministry to find ways of protecting Britain from possible attack from enemy aircraft. Through Tizard’s intervention Hanbury Brown came to be recruited into an experimental project instigated by Robert Watson-Watt, to develop a system of radio-location using pulse/echo technique for aircraft detection. In August 1936 Hanbury Brown joined what would grow into the Telecommunications Research Establishment (TRE) and helped develop Chain Home, an air surveillance system of ground stations along the East and South Coasts that proved vital in the 1940 Battle of Britain. From the autumn of 1937 he worked in the airborne radar group under E. G. Bowen, which transferred to the USA in 1942 for a joint British-American mission on air defence. Returning three years later he rejoined TRE, helping the Air Historical Branch of the Air Ministry write an account of airborne radar and working on the application of the pulsed navigational aid GEE to civil aviation. A research consultancy set up by Watson-Watt in 1947 offered more interesting prospects for the conversion of wartime developments into peacetime technologies. Hanbury Brown allowed himself to be recruited and worked as a consulting engineer until Watson-Watt decided to move the firm to Canada. After pondering a number of career possibilities, he returned to academia in the autumn of 1949, when he started as a Ph.D. student in radio astronomy at the University of Manchester.

It has been said that the story of radio astronomy effectively began with the return of physicists from wartime radar development and ‘with their eagerness and ability to follow up certain discoveries made accidentally in a military context’ (D. Edge and M. Mulkay, Astronomy Transformed. The Emergence of Radio Astronomy in Britain (John Wiley, 1976), ix). Hanbury Brown very much exemplifies this story – though as an engineer as much as a physicist. His impact at Jodrell Bank, where Manchester’s radio astronomy group was based, was instantaneous. The development for which he achieved his greatest distinction lay in interferometry, indeed in showing how the principle of the intensity interferometer could be applied to optical interferometry. In 1956, he and the mathematician R.Q. Twiss showed on the basis of a laboratory experiment that the time of arrival of photons at two separate detectors was correlated (Hanbury Brown-Twiss effect). Physicists struggled with the idea, photon correlation being inconceivable from a quantum theoretical perspective; yet Hanbury Brown and Twiss proceeded to demonstrate on the example of the star Sirius how the phenomenon could be used in an interferometer to measure the apparent angular diameter of bright visual stars. Their work earned them a Michelson Medal for opening up the subject of quantum optics.

With the controversy over the Hanbury Brown-Twiss effect in full swing, Hanbury Brown proposed a large optical interferometer to measure the diameters of other main sequence stars. The Department of Scientific and Industrial Research agreed to fund the initial design costs and a large part of the eventual construction costs for an instrument consisting of two reflectors, mounted on a circular railway track 188 metres in diameter. The instrument was manufactured in Britain and Italy, but built in the Australian bush near Narrabri in New South Wales. The construction of the Narrabri Stellar Intensity Interferometer (NSII) at a fairly remote site was a heroic task, which kept Hanbury Brown full-time in Australia. In 1964, two years into the mission, he resigned from the personal chair which the University of Manchester had created for him in 1960, and accepted an appointment as Professor of Physics (Astronomy) at the University of Sydney. Despite tempting offers to go elsewhere after the NSII was decommissioned in 1974, he stayed on to explore a next generation instrument. This was not to be another intensity interferometer as initially envisaged, but a modernised Michelson interferometer. As Hanbury Brown himself was keen to emphasize, the development of this technically demanding instrument, the Sydney University Stellar Interferometer (SUSI), became the project of his colleague John Davis. It took almost twenty years to design the SUSI and to ensure that it was built. The SUSI opened in 1991, ten years after Hanbury Brown officially retired.

Hanbury Brown’s commitments to science manifested beyond the instruments and institutions with which he was most visibly affiliated. His involvements in such ventures of the 1970s as the Anglo-Australian-Telescope (AAT) or the Science Task Force both illustrate in their way how he envisaged future science. For instance, he used a job interview for the directorship of the new AAT to criticize centralist tendencies in Australian science funding, pleading for greater equality of the state universities vis-�-vis the flagship of Australian academia, the Australian National University. Likewise, as a member of the Science Task Force, a consultative committee of the Royal Commission on Australian Government Administration, he expressed his concerns over changes in the scientific ethos under government funding, which had become the norm after World War II. The now classic report of the Task Force, Towards Diversity and Adaptability (1975), was imbued with the ideal of scientific autonomy.

Over the years Hanbury Brown developed his dimension as a public scientist also in his writings and his lectures. He became an interpreter of science who explained to non-expert audiences his particular science, interferometry, as well as his views on the scientific enterprise more broadly. His broadcasts and other public performances bear this out, as do such monographs as his account of The Intensity Interferometer (1974) or the more philosophical Man and the Stars (1978) and The Wisdom of Science (1986). In his last publication, There are no Dinosaurs in the Bible, which he had written for his grandchildren and which appeared posthumously, he returned to a theme that had occupied him over a number of decades, the relations between science and religion. Another subject close to his heart was his wartime experiences. Hanbury Brown’s friendships from the radar days lasted a lifetime, and he continued to explore the history of radar with younger radar buffs, through reunions and celebratory occasions, in television programmes and sound recordings, and in his autobiography, Boffin: A Personal Story of the Early Days of Radar, Radio Astronomy and Quantum Optics (1991). Indeed, he was rumoured to have been the prototype prompting the expression ‘boffin’ (for a technological expert).

Hanbury Brown accumulated many honours during his long career. He was elected a Fellow of the Royal Society in 1960 and a Fellow of the Australian Academy of Science in 1967. In 1986, he was made a Companion of the Order of Australia.� He married Hilda Heather Chesterman in 1952. They had one daughter and two sons (twins). He died on 16 January 2002.

DESCRIPTION OF THE COLLECTION

Although there is significant material from Hanbury Brown’s education and early career, including wartime service, the bulk of this archive dates from the 1960s to the late 1990s and there is thus a pronounced emphasis on Hanbury Brown’s career following his departure for Australia. His war-time research, the transition to radio astronomy and the intense collaborations in the Jodrell Bank group are more sketchily documented, as is in fact his and John Davis’s quest for an instrument to succeed the NSII.

Section A, Biographical, presents a wide range of material relating to Hanbury Brown’s life and career. It includes the contents of a boxfile of biographical correspondence from the 1930s and 1940s documenting his education, wartime service and immediate postwar career. There are transcripts of interviews, proceedings of conferences to honour his achievements, and drafts (with correspondence) of his Royal Society/Australian Academy of Science Biographical Memoir and other tributes and obituaries. The section includes family material, including letters to his wife Heather before and after their marriage, certificates of education and of awards, and a series of diaries 1936-1998. There is also photographic material.

Section B, Radar, documents aspects of Hanbury Brown’s war work from early experiments at Martlesham airfield in Suffolk to memorabilia (including a poem on the ‘radar man’). His time with the Combined Research Group at the Naval Research Laboratory in Washington, DC, USA, is covered by memoranda and photostats of research reports. Of particular interest is the material relating to the claim on the part of the airborne radar team for an award for the design and development of metre-wave airborne radar. This section further includes reunion activities in the 1990s.

Section C, Jodrell Bank, is the smallest section. It contains an early letter to J. A. Ratcliffe in which Hanbury Brown outlined a radio interferometer of high resolution, pen-recorded inscriptions of signals from Cassiopeia and Sirius, and a notebook with measurements on Sirius that provided practical vindication of the Hanbury Brown-Twiss effect. There are memoranda and proposals on instruments, notably the steerable radio telescope and the interferometer that was eventually built in Narrabri. The development of this latter instrument is further documented by a notebook containing detailed calculations and tests of sample equipment for the future NSII. A number of photographs show various Jodrell Bank individuals and apparatus.

Section D, Australia, essentially covers three astronomical instruments and their genesis. Correspondence, notebooks, photographs and promotional materials document the NSII. The story of the successor instrument, the SUSI, is represented chiefly by photographs of an early model showing a Very Large Stellar Intensity Interferometer, a subsequent proposal of a Michelson interferometer, and discussions between Hanbury Brown and John Davis. There is also correspondence re the AAT and the future of science and engineering in the University of Sydney.

Section E, Research Files, the second-largest section, contains research materials which Hanbury Brown accumulated over many decades. These files testify to three foci of enduring interest on his part, (a) the story of radar, (b) radio astronomy, and (c) reflections about science. The history of radar is documented by original documents and pamphlets, correspondence with both fellow radar pioneers and younger radar buffs, memoirs, and drafts of equipment biographies. The subsection on radio astronomy includes literature on various types of interferometers and on quantum theory, correspondence and draft publications on the behaviour of photons (these from the time of the controversy over the Hanbury Brown-Twiss effect), and a special section on his ‘dear friend Sirius’ (Letter to J. M. Bennett, 1 June 1994, H.31). A subsection is dedicated to historical topics in radio astronomy. Material on reflections about science consists of his notes on science-historical literature; correspondence, notes and literature on science’s relations with religion; and general articles.

Section F, Publications and Lectures, is the largest component of this collection. It documents some of Hanbury Brown’s publications, including offprints, books, reviews and newspaper articles, starting with his 1935 publication on the cathode-ray oscillograph. The lectures portion presents drafts, outlines and index card notes for many of Hanbury Brown’s speaking engagements over almost five decades, including his broadcasts. This material is qualitatively heterogeneous, ranging from expert conference papers to light-hearted dinner toasts. Sound and video recordings of some of these can be found in Section J.

Section G, Societies and Organisations, is another short section. It documents a few of Hanbury Brown’s involvements with a variety of bodies from the National Centre for Basic Sciences in Calcutta, India, to the Astronomical Society of Australia. There is correspondence with the Royal Society and with the Institution of Electrical Engineers. Material includes copies of reports (co-authored by Hanbury Brown) to the International Scientific Radio Union (URSI) and to the Royal Commission on Australian Government Administration.

Section H, Correspondence, presents several series of correspondence which together span seven decades. There are three alphabetical sequences, one dating from the 1940s to the early 1950s, the second consisting of named correspondents, the third dating chiefly from the 1980s and 1990s (with a few earlier letters). The first sequence includes family letters and correspondence about the Sir Robert Watson-Watt & Partners consultancy. Hanbury Brown’s named correspondents in the second sequence are colleagues and friends from the days of radar and early radio astronomy, and his colleague John Davis. The third sequence ranges over a multitude of correspondents and topics. It reflects chiefly Hanbury Brown’s activities after his return from Australia in 1991. This section closes with a notebook listing all the letters Hanbury Brown sent between 1990 and 1996.

Section J, Non-textual media, spans audiotapes, videotapes, other visual material, and computer disks. The audiotapes date from 1973 to 1999 and include recordings of Hanbury Brown’s wife Heather. Videotapes are principally of Hanbury Brown’s contributions to television documentaries and interviews on his wartime work. The visual material includes an extensive slide collection, which appears to have served him as a store on which to draw for his lecturing activities. The computer disks reflect both Hanbury Brown’s changing word processing equipment and his diverse activities, from his writings to his correspondence with colleagues, friends, institutions, businesses and so forth. Not all of these disks have been deciphered at this stage of processing.

LOCATION OF FURTHER MATERIAL

A substantial portion of Hanbury Brown’s personal archive was destroyed in 1961 owing to a misunderstanding (Letter to J. P. Wild, 16 January 1974, H.127). Some material relating to his Jodrell Bank period can be found in the papers of A. C. B. Lovell in the Jodrell Bank Archive at the John Rylands University Library of the University of Manchester. Hanbury Brown left many of the documents relating to his work in astronomy in Australia to the University of Sydney, where he thought they belonged. These are in the University Archives of the University of Sydney and include correspondence regarding the intensity interferometer at Narrabri, technical papers, funding and general correspondence, 1957-1983. There is also correspondence on the AAT, 1967-1974, and an audio tape interview on his retirement in 1981. Further material, notably 27 scrapbooks compiled by Hanbury Brown’s wife Heather, is in the hands of the family. It is anticipated that they will be deposited at the Royal Society to join this collection in due course.

Trim. Also includes technical manuals for the use of equipment (in original envelopes). R. Trim was an engineer who started to work on Identification Friend or Foe (IFF) equipment in the mid-1950s. IFF had been developed as a means of positively distinguishing friendly from enemy aircraft. It relied on a piece of equipment aboard the aircraft, known as the ‘transponder’ (a receiver/transmitter).	1941-1943, 1990
B.33	Correspondence Correspondence with J. W. S. Pringle re the transfer of the airborne radar team to the USA and re continued work on Rebecca/Eureka. Also includes an original technical manual for a Eureka beacon type AN/PPN-1, printed in Washington, DC, USA. J. W. S. Pringle was a Cambridge biologist with whom Hanbury Brown developed Rebecca/Eureka. Hanbury Brown had departed for the USA in December 1942 and they continued to collaborate by correspondence. The design for the American Eureka beacon type AN/PPN-1 was Hanbury Brown’s.	1943
B.34	‘History of Rebecca/Eureka’ by E. K. Williams Typescript of E. K. Williams’ account of Rebecca/Eureka. E. K. Williams was one of the key figures in the development of Rebecca/Eureka.	1985

B.37	1941-1947 Includes correspondence and memoranda, and newspaper cuttings on persons credited with the discovery of radar. Further includes material re morale within TRE following the end of World War II and re the conversion of GEE for civil use. After his return to TRE in 1945 Hanbury Brown worked on the application of the pulsed navigational aid GEE (short for ‘Grid’ and pronounced simply as ‘G’) to civil aviation. Support for this plan was not universal even within TRE. Hanbury Brown represented the UK delegation to the Provisional International Civil Aviation Organisation (PICAO) in Montreal in 1946, where he discovered that GEE was too large, too heavy, too expensive and too complicated to operate for it to offer a promising technology for international civil aviation.
B.38	n.d. Includes a poem on the ‘radar man’ and a report on the GEE system.

SECTION C	JODRELL BANK, C.1-C.13 After the end of World War II, P. M. S. Blackett and A. C. B. Lovell assembled a group of radar researchers in Manchester. They established themselves at Jodrell Bank, a field twenty miles south of Manchester that was owned by the University.	c.1949-1962, 1966
C.1	Letter to J. A. Ratcliffe, 9 June The letter outlines a radio interferometer of high resolution.	1950
C.2	Cassiopeia Pen-recorded inscription of a radio signal received on 1 August 1950 between 01:56 and 03:49, recording the transit of the intense radio source Cassiopeia through the beam of the 218 ft paraboloid at Jodrell Bank.	1950
C.3	Steerable telescope Hardback bound copy of A. C. B. Lovell’s ‘Memorandum on a 250ft aperture Steerable Radio Telescope’ (1951). Construction of this telescope (known as ‘Mark 1A’) began in October 1952. Mark 1A entered service only a few months before it was involved in tracking the Soviet Sputnik satellite in October 1957. In 1987 it was renamed the ‘Lovell Telescope’.	1951

C.7	Sirius inscription Pen-recorded inscription of signal received on 15 November 1955 between 21:30 and 02:40. Hanbury Brown first tested his intensity interferometer on the star Sirius. He published the observational details (gathered in November and December 1955) and the results a year later in a paper (with the mathematician R. Q. Twiss). Earlier in 1956, Hanbury Brown and Twiss had elucidated the principle behind these measurements, arguing on the basis of a laboratory experiment that the time of arrival of photons at two separate detectors was correlated (Hanbury Brown-Twiss effect). Their subsequent publication of the Sirius data demonstrated how this phenomenon could be used in an interferometer to measure the apparent angular diameter of bright visual stars. The Sirius-paper provided a practical vindication of the then much-disputed Hanbury Brown-Twiss effect.	1955
C.8	Sirius notebook Hardback notebook, used from the front for calculations of signal/noise ratio and angular diameter of Sirius, estimates of performance of a system with larger mirrors and of errors in calculated diameter. Used from the back for measurements on Sirius.	1955-1956

D.1-D.24	NARRABRI STELLAR INTENSITY INTERFEROMETER Chiefly photographic documentation re the Narrabri Stellar Intensity Interferometer (NSII). The NSII site was twelve miles from the town of Narrabri in northern New South Wales, Australia, about 350 miles from Sydney by road, and about 600 ft above sea level. In situ assembly of the instrument began in spring 1962. It was successfully tested on Vega in 1963, finally going into service in 1965.	1958-1975, n.d.

D.2, D.3	Mechanical and financial problems Chiefly correspondence between Dunford & Elliott, Ltd., H. Messel, Hanbury Brown, W. Mansfield Cooper and Mullard Ltd. Also includes correspondence with the Air Force Office of Scientific Research of the American Department of Defense and a financial statement of the Chatterton Astronomy Department. 2 folders. Mullard Ltd supplied the correlator of the NSII. The Chatterton Astronomy Department of Sydney University was named after the wealthy donor S. Chatterton (see D.7).	1962-1963, 1970, 1975
D.4-D.17	Photographs See also D.43.	1961-1969
D.4	Model Monochrome photograph of a model of a reflector. The model was made by Dunford & Elliott and was about six inches high. It was used as part of a ‘sales kit’ to persuade the DSIR to fund the project.	n.d.
D.5	Site 1 photograph and 1 negative of the NSII site. The interferometer was built on property belonging to P. Miller.	n.d.
D.6-D.13	Construction	1961x1965
D.6	Assembly of the reflectors 7 monochrome photographs of the reflector frameworks prior to shipping. All component parts except the correlator were completed by August 1961. Time and financial constraints prevented proper assembly and testing, but the reflector frameworks were assembled on the shipyard of Saunders-Roe at Beaumaris and given a few tests. The weight of the hexagonal mirrors (252 on each reflector) had to be simulated because they were shipped directly from Italy (where they were made) to Australia.	1961
D.7-D.10	Assembly of the interferometer Assembly of the interferometer (minus the correlator) began soon after Hanbury Brown’s arrival in Australia in January 1962. Tests of the reflectors were delayed by damage to some of the hexagonal mirrors during the removal of the protective plastic coating. Gaps in the light collecting surface of the reflectors show which mirrors needed recoating or other work done.	1962x1965
D.7 /…	Photographs identified by J. Davis 8 photographs. Communication from Prof. John Davis, 27 January 2007: Photograph 1: ‘Hanbury on one of the reflectors. Here the mirrors have had their coatings removed - the missing ones have gone back to Italy for recoating.’ Photograph 2: ‘The person with Hanbury is the late Professor Ed Ney from the University of Minnesota who spent a sabbatical year with us.’ Photograph 3: ‘The man on the left of Hanbury is Professor Ed Ney again (see Photograph 2).’ Photograph 4: ‘On the left is Mr. Tony Smith from the Sheffield firm Dunford and Elliot who were responsible for the entire control system of the instrument. Tony was with us for a long time - I am not sure just how long but it was more than 2 years - installing and commissioning the control system. On the right is the late Mr. Graham Gifford who lived in Narrabri and was our caretaker for the life of the instrument. As a piece of trivia it turned out that he went to the same school as me in Essex although a bit before me!’ Photograph 5: ‘The man with Hanbury is Lord De L’Isle, Governor General of Australia (1961-65). The occasion was a visit by the Governor General to the Intensity Interferometer at Narrabri [in March 1964].’ Photograph 6: ‘This was the same occasion with Lord De L’Isle being welcomed to the Intensity Interferometer. The man introducing the Governor General to the line of people is the late Mr Stan Chatterton who made a major donation to the School and after whom the Chatterton Astronomy Department that Hanbury and I headed was named. I think the donation was �200,000 in ~1960. Unfortunately, since I retired, the named Departments in the School, of which there were five, have been abolished. The people in the line-up from the left are: Professor Harry Messel, Head of the School of Physics at the time, Hanbury, Mr. Peter Miller (hidden by the Governor General but the owner of the property on which the interferometer was built), Betty Miller (Peter’s wife), myself, Dr Roy Allen, Mr Michael Yerbury (a Ph.D. student, now Dr Yerbury). Regarding the mirrors - they certainly look as if they may still have the protective coating on them but I really can’t remember and the reflection can be very confusing depending on how far away from the mirrors you are.’ Photograph 7: ‘This was unrealistic but made for a good picture! The people in the picture are Peter Miller, the property owner on the left with his horse, and our caretaker Graham Gifford on the right. As you can see, if the reflector was moved, they would be in the way of the catenary cable. This [photograph] is unrealistic as they are boiling a billy - with a proper kitchen 50 metres away - in a position that would stop the reflector being moved. [This photographer] liked the idea of capturing the outback feeling for the picture!’ Photograph 8: ‘I think it is Hanbury standing on the reflector and I am fairly sure that the face reflected is that of Graham Gifford with more hair and a beard that he didn’t have in earlier pictures.’	1962x1965 /…
D.8-D.10	Other photographs 20 monochrome photographs. These include images of details of the hexagonal mirrors, mounted on the reflectors; pictures of Hanbury Brown, visiting astronomers, the engineers and photographers together with the reflectors; and further photographs from the official visit of the Governor General of Australia (see D.7). 3 folders.	1962x1965
D.11	First tests 7 monochrome photographs, taken during the first reflector testing. The reflectors were pointed horizontally at a distant gum tree on which a lamp had been mounted. After each of the 252 mirrors on each reflector had been adjusted individually, Jupiter was tracked over a wide range of elevations. See also C.10. Communication from Prof. John Davis, 19 February 2007: ‘What the [two larger] pictures show is the perspex graticule we mounted at the focus of a reflector to give us a scale for aligning the images from the individual mirrors into a single “blob” of light - and then for photographing the images of Jupiter to observe what happened when the reflector was tilted in elevation. [One of them] shows the assembly of individual images but I am not sure what the scattered flare of light is - the comment [on the back] regarding “by garage lights” suggests that it is an out-of-focus reflection of lights in the garage where the reflectors were housed - by having them on, the graticule can be seen. In the [smaller] pictures, which show various image assemblies, you can just make out part of the graticule in some but not as clearly.’ ‘I can’t tell you what the individual image assemblies are except that they were taken during the alignment process using the lamp in a distant gum tree! I went through that alignment process of over 500 mirrors (for the two reflectors) more times than I care to remember as, in use, they gradually became mis-aligned. I accepted responsibility of re-doing it every few months with the aid of students!’ ‘One telling point regarding the comments is “Red 119 mirrors” which almost certainly means we had taken the faulty mirrors off the reflector at that stage. We mounted all the mirrors on each reflector before removing the protective layer and the alignment tests couldn’t be done with it on. So it looks as if the faulty mirrors were removed a bit sooner than I thought.’ The first reflector tests revealed substantial technical problems for which there were no simple solutions.	October 1962
D.12, D.13	Completed interferometer 11 photographs (7 monochrome, 4 colour) and 3 colour transparencies showing the two reflectors and the Narrabri site. 2 folders.	1962x1965
D.14, D.15	Control desk and correlator 7 monochrome photographs of the control desk and the electronic correlator. Also shown is A. Browne of Mullard Ltd. 2 folders. The electronic correlator was produced in the Mullard Research Laboratories in Redhill, Surrey. It arrived in Narrabri in January 1963.	n.d.
D.16	Promotion 2 monochrome photographs and 1 colour transfer. Photograph 1 shows Hanbury Brown during an interview with P. Pockley, with the reflectors in the background. Photograph 2 shows a wall display that illustrates what the stellar interferometer can do. The transfer displays one of the reflectors and other symbols. Communication from Prof. John Davis, 9 March 2007: ‘[The transfer] was done by the town of Narrabri - presumably the local council had something to do with it. It was obviously done to promote the town as it shows the three major farming activities in the region - wheat, sheep and cotton. In the ‘60s the town was very proud of the fact that the Intensity Interferometer had been located locally and that explains the dominant image of a reflector. In the background is a representation of the local mountains - the Nandewar Range whose highest peak is Mount Kaputar (5000 feet).’	n.d.
D.17	Miscellaneous 2 photographs of Hanbury Brown with one of the reflectors. Photograph 1 (monochrome) was taken in the shed that houses the reflectors; it is inscribed ‘12 March 1966’. Photograph 2 (colour) was taken outdoors in January 1969.	1966, 1969

D.25-D.38	SYDNEY UNIVERSITY STELLAR INTERFEROMETER The Sydney University Stellar Interferometer (SUSI) was the successor of the NSII. It was built in Culgoora near Narrabri. An earlier proposal envisaged a larger and more sensitive intensity interferometer, the VLSII (Very Large Stellar Intensity Interferometer). This plan was abandoned in favour of a Michelson interferometer, which, as Hanbury Brown was keen to emphasize, became J. Davis’s project. The SUSI opened in 1991.	1969-1999

D.27	Model, VLSII 4 photographs (2 monochrome, 2 colour) of a scale model of an instrument to succeed the NSII. The proposed intensity interferometer featured four coelostats running on straight tracks, with a central building to house the coelostats. Unlike this successor model, the NSII had used two concave reflectors running on a circular track. The proposed new instrument would have been about 80 times more sensitive than the NSII. It was never built.	1974
