Built in 1769 as a private observatory for King George III, Kew Observatory was taken over in 1842 by the British Association for the Advancement of Science (BAAS). It was then quickly transformed into what some claimed to be a ‘physical observatory’ of the sort proposed by John Herschel – an observatory that gathered data in a wide range of physical sciences, including geomagnetism and meteorology, rather than just astronomy. Yet this article argues that the institution which emerged in the 1840s was different in many ways from that envisaged by Herschel. It uses a chronological framework to show how, at every stage, the geophysicist and Royal Artillery officer Edward Sabine manipulated the project towards his own agenda: an independent observatory through which he could control the geomagnetic and meteorological research, including the ongoing ‘Magnetic Crusade’. The political machinations surrounding Kew Observatory, within the Royal Society and the BAAS, may help to illuminate the complex politics of science in early Victorian Britain, particularly the role of ‘scientific servicemen’ such as Sabine. Both the diversity of activities at Kew and the complexity of the observatory's origins make its study important in the context of the growing field of the ‘observatory sciences’.

2 The origins of the phrase ‘Magnetic Crusade’ are unclear. Carter, Christopher, ‘Magnetic fever: global imperialism and empiricism in the nineteenth century’, Transactions of the American Philosophical Society (2009) 99, Part 4, pp. xv–xviGoogle Scholar, finds no evidence that the phrase was used in the lobby for the project in the 1830s and that it was first used in 1842 in an American textbook on electricity and magnetism. Elias Loomis's 1848 call for a ‘grand meteorological crusade’ along the lines of the British magnetic effort strengthens the idea that the term ‘Magnetic Crusade’ was American in origin – see Fleming, James Rodger, Meteorology in America, 1800–1870, Baltimore: Johns Hopkins University Press, 1990Google Scholar, p. 77.

Ratcliff, Jessica, The Transit of Venus Enterprise in Victorian Britain, London: Pickering & Chatto, 2005Google Scholar, p. 27, notes that the role of scientific military officers is poorly covered in modern scholarship of Victorian science. This is now starting to be rectified – see e.g. Reidy, Michael S., Tides of History: Ocean Science and Her Majesty's Navy, Chicago and London: The University of Chicago Press, 2008CrossRefGoogle Scholar, who discusses how elite academic scientists collaborated with naval personnel in global tidal research in the early 1830s.

The chapter on Kew Observatory in Howarth, O.J.R., The British Association for the Advancement of Science: A Retrospect. 1831–1921, 2nd edn, London: BAAS, 1931Google Scholar, naturally plays up the role of the British Association.
