Over its long history, the buildings of the Royal Observatory in Greenwich were enlarged and altered many times, reflecting changing needs and expectations of astronomers and funders, but also the constraints of a limited site and small budgets. The most significant expansion took place in the late nineteenth century, overseen by the eighth Astronomer Royal, William Christie, a programme that is put in the context of changing attitudes toward scientific funding, Christie's ambitious plans for the work and staffing of the Observatory and his desire to develop a national institution that could stand with more recently founded European and American rivals. Examination of the archives reveals the range of strategies Christie was required to use to acquire consent and financial backing from the Admiralty, as well as his opportunistic approach. While hindsight might lead to criticism of his decisions, Christie eventually succeeded in completing a large building – the New Physical Observatory – that, in its decoration, celebrated Greenwich's past while, in its name, style, structure and contents, it was intended to signal the institution's modernization and future promise.

8 H.H. Turner, chief assistant at Greenwich from 1884 to 1893, saw two ‘reconstructions’ at Greenwich, one, under Airy, that reorganized its ‘routine work’ and one, under Christie, that ‘has equipped it for playing its part in “modern astronomy”’. This responded to ‘a revolution in almost all departments of Astronomy, theoretical and practical’, beginning in 1875, the year that saw the application of the gelatin dry-plate processes to astrophotography, but which existing observatories only really responded to in the 1880s.

10 Donnelly, Marian Card, A Short History of Observatories, Eugene: University of Oregon Books, 1973, p. 1Google Scholar, sees observatory architecture as essentially dependent on telescope design: ‘a kind of mechanical equipment had been invented which required some building, or portion of a building, specifically designed for its use’. While the architecture of laboratories, universities and museums has been considered in the history of science, that of observatories has been subject to less analysis than it deserves. An important recent dissertation, Alistair Marcus Kwan, ‘Architecture of astronomical observation: from Sternwarte Kassel (ca. 1560) to the Radcliffe Observatory (1772)’, PhD dissertation, Yale University, 2010, in part rectifies this by combining history of astronomy and architectural history to develop important insights into observatory buildings and – crucially – the relationship between design and use of buildings and the use of instruments. However, his analysis of Greenwich does not take sufficient note of the chronological development of the site and, of course, the radical developments of nineteenth-century astronomy are outside the scope of the study.

11 George Airy considered this the chief disadvantage of the site in 1875, when he commented on ‘the limited extent of the hill’. However, he felt that this inconvenience was ‘far overbalanced by its advantages’, Report of the Astronomer Royal, London: Royal Observatory Greenwich, 1875, p. 26. All of the Astronomer Royal's Annual Reports will hereafter be cited as Report with the author (Airy or Christie) and year.

13 On one side was the Thompson twenty-six-inch photographic refractor (1896), guided by the 12¾-inch refractor by Merz (Great Equatorial, 1859), and the Thompson nine-inch photoheliograph (presented 1891); on the other side was the Thompson thirty-inch photographic reflector (1896) with spectroscope. The refractor and reflector were moved to Herstmonceux in 1956–1957, where they can still be seen at the Observatory Science Centre.

It is, however, in great popular request’), ‘cosmical physics’, including his own observations of the motions of pendulums down mines, preparations for eclipse and transit of Venus expeditions, work relating to national standards, and assistance in training officers in surveying work.

Proctor, who, much like Airy, believed that government should fund ‘scientific researches tending to advance the material interests of the nation’, but that regular funding of speculative research ‘might excite hostility to science and to scientific men which would most seriously injure the prospects of science in this country’.

34 Minutes of the Board of Visitors, Royal Greenwich Observatory Archives, Cambridge University Library, RGO 55/1 (hereafter RGO).

35 Airy's repeated statements about the ROG's role, and his opposition to equatorial instruments and other diversions from this role, suggest that members of the Board of Visitors were requesting change. Airy himself became a Visitor, 1884–1891, and it is interesting to speculate on his attitude to the changes implemented under Christie. The minutes are frustratingly uninformative about discussion and disagreement among the Board's members. RGO 55/1.

36 However, it is not clear that this appointment was the result of a change of policy. Two other individuals were reputedly approached before Christie regarding the post of Astronomer Royal, John Couch Adams and J.W.L. Glaisher, both of whom were primarily thought of as mathematical astronomers, as Airy had been on his appointment.

37 The archives include a list of resolutions made by the Board of Visitors relating to these points, which illustrates forcefully their belief that, first, expansion of the ROG was inevitable and, second, the Admiralty should be prepared to pay for it: ‘Copies of Resolutions passed since 1886 by the Board of Visitors relating to the increase in the duties performed at the Royal Observatory and to the difficulties experienced in consequence of the scattered character of the Observatory Buildings’ (1886–1892), RGO 55/7.

38 The Carte du ciel was a photographic stellar mapping project, initiated in the 1880s in Paris, involving twenty observatories around the word. As a photographic project it expanded the work of the ROG, and it was of astronomical rather than navigational significance, although it continued the focus on accurate mapping of the skies. See Lamy, Jérôme (ed.), La carte du ciel: Histoire et actualité d'un projet scientifique international, Les Ulis: EDP Sciences, 2008Google Scholar. Christie felt that it was ‘fitting’ for ‘Greenwich, as the National Observatory, to take its share in the scheme’: Report (1887), p. 21, and (1888), p. 20.

51 Christie, Report (1909), p. 30. There was also a brief experiment of employing women at the Observatory c.1891–1895. Christie, concerned about the quality of candidates and attempting to persuade the Admiralty to agree to the expansion of the permanent workforce, found the hiring of women as supernumerary computers was a useful stopgap. They could be paid at a low rate despite having excellent qualifications, for a handful of women with ambitions in the world of astronomy took up the opportunity. Like Christie's other computers, these women were trained to make observations. See Brück, Mary T., ‘Alice Everett and Annie Russell Maunder: torch bearing women astronomers’, Irish Astronomical Journal (1994) 21, pp. 280291Google Scholar. It is not clear why this experiment was discontinued. Perhaps no more women put themselves forward, or perhaps Christie felt that his staffing reforms meant that he now had enough competent male computers and observers.

The term ‘museum’ was used in the sense of a store or repository, and although the instruments’ historic interest was mentioned, there was no attempt to capture the Observatory's history in this way. The oldest instruments belonging to the Observatory, those of Halley, Bradley and others, remained displayed on the walls of the Transit Circle Room. Though the museum was eventually fitted with glass cases, these seem to have been for the convenience of making an inventory rather than display.

80 Thompson’s three telescopic gifts, of which this was the first, were likened to the private patronage that was having such a marked effect on observatories and telescope-building in the US. He was clearly enthusiastic about having an impact on the kind of astronomy being done in a government-funded institution, for he made it a condition of the later gift that the telescope be used for photographic purposes and, apparently, ‘feeling that the astronomy of the future is to be photographic’, he was of the opinion ‘that England should be well equipped in this arm’.
