David Gill - Magnificent and Desirable Astronomer
  This paper was given to mark the centenary of the death of David Gill, the foremost British astronomer in the last quarter of the 19th century and into the 20th century. Gill abandoned a successful career as a clock and watchmaker. His speciality was in astrometry, an area of astronomy of both practical and scientific importance that tended to be eclipsed in the 20th century by the rise of astrophysics. As Her Majesty's Astronomer at the Cape of Good Hope for 27 years, David Gill was admired for his prolific contribution to highly accurate and trustworthy results. David Gill's collaboration was desired by leading astronomers of the day and he was the only southern hemisphere representative on the hugely important Conference Internationale des Etoiles Fondamentales of 1896. He created with Jacobus Kapteyn the first extensive star catalogue derived from photographic plates (the CPD), including over 450,000 stars. He was an initiator of the biggest multi-national and multi-observatory project of the century, taking on the role of President of the International Commission overseeing the Carte du Ciel project. David Gill raised the Cape of Good Hope observatory from a rather run-down jobbing observatory of the Admiralty to the best observatory in the Southern hemisphere. He acquired in the process the reputation of an expert in precision instrument design. He also made a substantial name for himself as semi-official director of the geodetic survey of South Africa. Overall David Gill was highly influential, respected and well liked. With the resurgence of interest in astrometry, the contribution of David Gill to astronomy is due for a re-assessment a century after he died.
