These letters and miscellaneous papers of Fearon Fallows sparked an interest in the history of the Royal Observatory at the Cape of Good Hope which, after the diversion of producing several books on later phases of the Observatory, has finally resulted in a detailed study of the origin and first years of the Observatory's life. Publication of this book coincides with the 175th anniversary of the founding of the Royal Observatory, e.G.H. Observatories are built for the use of astronomers. They are built through astronomers, architects, engineers and contractors acting in concert (if not always in harmony). They are constructed, with whatever techniques and skills are available, from bricks, stones and mortar; but their construction may take a toll of personal relationships, patience, and flesh and blood. Written histories of the founding and functioning of astronomical observa tories commonly concentrate on scientific and technical aspects, with but occasional glimpses of the human factors involved. In the account given in this book of the founding and first few years of operation of the Royal Observatory at the Cape of Good Hope the human side is not neglected. To emphasize that the personae involved were real people with personalities and idiosyncracies, living in an environment filled with domestic issues and daily problems rather than in sterile surroundings, liberal amounts of family, town and college anec dote and ambience are included. Extensive quotations from letters and docu ments generate some awareness of the nature of the contemporary life. In these, non-standard spelling, grammar and capitalization have been retained. Unlike the founding of other early observatories, where much of what happened may have been decided verbally and was therefore lost to the record, the building of the Observatory at the Cape was carried out at a location almost infinitely remote from the prime movers. His Majesty's Astronomer at the Cape had to write frequent reports of progress, contained in both official and private letters. The development of the Observatory is therefore quite fully, even repetitively, documented among these sources. Although an extensive search has been made, it is entirely possible that other material remains to be found - for example, Fallows mentions a travel journal that he kept during trips away from Cape Town. The original sources on which this book is based are located in the following institutions, the Directors of which are thanked for their permission to use relevant material: xi xii PREFACE The Royal Society of London; the Royal Astronomical Society; St. John's College, Cambridge; the Bodleian Library, Oxford; the Museum of the History of Science, Oxford; the British Library; the Public Records Office, Kew; the Humanities Research Center, the University of Texas at Austin; the Archives of the Royal Greenwich Observatory; Cambridge University Library; the Ob servatories, Cambridge; the Hydrographic Office, Taunton, Somerset; Wigan Public Library; the South African Astronomical Observatory; the Library of Parliament, Cape Town; the Cape Archives; the South African Library; the South African Museum; St. George's Cathedral, Cape Town; the Surveyor General's Office, Cape Town. Christie's of London are particularly acknowledged, for permission to use the recently revealed watercolour of the Royal Observatory (Figure 39). The following individuals have generously given of their time in aiding the author in this research: David W. Dewhirst, Frank James, J. Martin, Rupert F. Hurly, Nancy Warner, Arlene Fanaroff, Ethleen Lastovica, the late Phil Laurie. Gordon Davidson, descended from Fallows's sister Rebecca, kindly provided details of his family tree. Stuart Atkinson allowed the use of his photographs. Drummond Laing ably assisted in preparation of the photographic illustrations. As always, Penny Dobbie has lavished great care and patience on the author and the preparation of the manuscript. Publication of this book was aided in part by grants from the University of Cape Town and the Cape Tercentenary Foundation. CHAPTER 1 COCKERMOUTH TO THE CAPE VIA CAMBRIDGE The Origins of the Royal Observatory, CGH "The end of the eighteenth and beginning of the nineteenth centuries were remarkable for the small amount of scientific movement going on in this country, especially in its more exact departments .... Mathematics were at the last gasp, and Astronomy nearly so -I mean in those members of its frame which depend upon precise measurement and systematic calculation. The chilling torpor of routine had begun to spread itself over all those branches of science which wanted the excitement of experimental research".(32) This ringing indictment of the state of scientific Britain at the turn of the century. was made by one who tried as much as anybody to remedy the defects! - Sir John Herschel (1792-1871). To a large extent, science was "an elegant ornament of society, practiced by virtuosi", (33) as exemplified by the critic's father - Sir William Herschel - whose wealth of discoveries led Sir John to exclude the natural history of the heavens from his censure. As astronomy was almost the only science to have professional posts outside of the Universities, the criticism of these "exact departments" was especially sensitive. There were two established major observatories2 -the Royal Greenwich Observatory under the Astronomers Royal Nevil Maskelyne (1732-1811) from 1765 until 1811, and John Pond (1767-1836) until 1835, and the Radcliffe Observatory in Oxford under Thomas Hornsby (1733-1810) from 1772 until 1810 and Abram Robert son (1751-1827) from 1810 to 1827. Herschel clearly believed thattheir progress was uninspiring and it is not difficult to see why. During his long reign, Maskelyne added no new instrument to the Observa tort and of his industry at the Observatory "there is little to record. .. beyond the patient prosecution, year by year, of an immense amount of sober, practical work".(34) Of Pond, who issued a notorious minute stating that his employees should be "obedient drudges", Maunder says "Men who had the spirit of 1 The successes of British astronomy in the first third of the nineteenth century are included in the comprehensive "Report on the Progress of Astronomy during the present century" by G.B. Airy.(372) 2 There were a few small University and College observatories,(47) notably Glasgow, Aberdeen and Armagh, but these were not contributing significantly. 3 Maskelyne did, however, inform the Royal Society that the Greenwich instruments were no match for the ones in use on the Continent, as a result of which Maskelyne's successor took delivery of a magnificent new mural circle.(56)
