The Science and Engineering Research Council (SERC) was the UK agency in charge of publicly funded scientific and engineering research activities, including astronomy, biotechnology and biological sciences, space research and particle physics, between 1965 and 1994.
 The SERC also had oversight of the Royal Greenwich Observatory, Royal Observatory Edinburgh, the Rutherford Appleton Laboratory and the Daresbury Laboratory.
Eleanor Margaret Burbidge ("née" Peachey), FRS (born August 12, 1919 in Davenport) is a British-born American astrophysicist, noted for original research and holding many administrative posts, including Director of the Royal Greenwich Observatory.
4358 Lynn, provisional designation A909 TF, is a stony Eunomia asteroid from the central region of the asteroid belt, approximately 10 kilometers in diameter.
 It was discovered by British astronomer Philip Herbert Cowell at the Royal Greenwich Observatory on 5 October 1909.
 It was named for William Lynn, an assistant astronomer at the discovering observatory.
Geoffrey Ronald Burbidge FRS (24 September 1925 – 26 January 2010) was an English astronomy professor and theoretical astrophysicist, most recently at the University of California, San Diego.
 He was married to astrophysicist Margaret Burbidge.
The Director of the Royal Greenwich Observatory was the senior scientist responsible for the administration of the Royal Greenwich Observatory from 1972 until the institution's closure in 1998.
The Shepherd Gate Clock is mounted on the wall outside the gate of the Royal Greenwich Observatory building in Greenwich, Greater London.
 The clock, an early example of an electric clock, was a slave mechanism controlled by electric pulses transmitted by a master clock inside the main building.
 The network of master and slave clocks was constructed and installed by Charles Shepherd in 1852.
 The clock by the gate was probably the first to display Greenwich Mean Time to the public, and is unusual in using the 24-hour analogue dial.
Roberto Abraham, FRSC (b. 12 Apr 1965, Manila, Philippines) is a Canadian astronomer and is Professor of Astronomy at the University of Toronto and a Fellow of the Royal Society of Canada.
 Educated at UBC (BSc) and Oxford (DPhil), Abraham did post-doctoral work at the Dominion Astrophysical Observatory, the Institute of Astronomy, Cambridge and the Royal Greenwich Observatory.
The Royal Observatory, Greenwich (ROG; known as the Old Royal Observatory from 1957 to 1998, when the working Royal Greenwich Observatory, RGO, moved from Greenwich to Herstmonceux) is an observatory situated on a hill in Greenwich Park, overlooking the River Thames.
 It played a major role in the history of astronomy and navigation, and is best known as the location of the prime meridian, and thereby gave its name to Greenwich Mean Time.
 The ROG has the IAU observatory code of 000, the first in the list.
 ROG, the National Maritime Museum, the Queen's House and Cutty Sark are collectively designated Royal Museums Greenwich.
Keith Tritton is an astronomer and observatory manager who has worked in various different parts of the world.
 He joined the Royal Greenwich Observatory (then at Herstmonceux in Sussex) in 1967 as a research astronomer and later worked at the Radcliffe Observatory in South Africa and the Royal Observatory Edinburgh.
 He spent a number of years as a university lecturer in the Philippines and in Thailand.
 His particular interest is observational astronomy.
 He was head of the UK Schmidt Telescope in Australia and of the Isaac Newton Group of telescopes in the Canary Islands.
 In 1987, he returned to the Royal Greenwich Observatory and moved with them to Cambridge in 1990, where he became head of the Astronomy Division.
 He took early retirement in 1997.
 Between 1995 and 2011 he was an Associate Lecturer in astronomy and planetary science with the Open University.
The Dominion Observatory was an astronomical observatory in Ottawa, Ontario that operated from 1902 to 1970.
 The Observatory was also an institution within the Canadian Federal Government.
 The observatory grew out of the Department of the Interior's need for the precise coordinates and timekeeping that at that time could only come from an observatory.
 For several years they had used a small observatory on the Ottawa River for this purpose.
 In 1902, it was decided that Canada needed a larger national observatory similar to the Royal Greenwich Observatory in Britain.
