Astronomer Royal in the context of "George Biddell Airy"

Fort St. George (or historically, White Town) is a fortress at the coastal city of Chennai, India. Founded in 1639, it was the first English (later British) fortress in India. The construction of the fort provided the impetus for further settlements and trading activity, in what was originally an uninhabited land. Thus, it is a feasible contention to say that the city (named Madras since before the arrival of the Europeans until July 1996) evolved around the fortress. The fort currently houses the Tamil Nadu legislative assembly and other official buildings.

The Royal Observatory, Greenwich (ROG; known as the Old Royal Observatory from 1957 to 1998, when the working Royal Greenwich Observatory, RGO, temporarily moved south from Greenwich to Herstmonceux) is an observatory situated on a hill in Greenwich Park in south east London, overlooking the River Thames to the north. It played a major role in the history of astronomy and navigation, and because the Prime Meridian passed through it, it gave its name to Greenwich Mean Time, the precursor to today's Coordinated Universal Time (UTC). The ROG has the IAU observatory code of 000, the first in the list. ROG, the National Maritime Museum, the Queen's House and the clipper ship Cutty Sark are collectively designated Royal Museums Greenwich.

The observatory was commissioned in 1675 by King Charles II, with the foundation stone being laid on 10 August. The old hilltop site of Greenwich Castle was chosen by Sir Christopher Wren, a former Savilian Professor of Astronomy; as Greenwich Park was a royal estate, no new land needed to be bought. At that time the King also created the position of Astronomer Royal, to serve as the director of the observatory and to "apply himself with the most exact care and diligence to the rectifying of the tables of the motions of the heavens, and the places of the fixed stars, so as to find out the so much desired longitude of places for the perfecting of the art of navigation." He appointed John Flamsteed as the first Astronomer Royal. The building was completed in the summer of 1676. The building was often called "Flamsteed House", in reference to its first occupant.

Edmond (or Edmund) Halley FRS (/ˈhæli/; 8 November [O.S. 29 October] 1656 – 25 January 1742 [O.S. 14 January 1741]) was an English astronomer, mathematician and physicist. He was the second Astronomer Royal in Britain, succeeding John Flamsteed in 1720.

From an observatory he constructed on Saint Helena in 1676–77, Halley catalogued the southern celestial hemisphere and recorded a transit of Mercury across the Sun. He realised that a similar transit of Venus could be used to determine the distances between Earth, Venus, and the Sun. Upon his return to England, he was made a fellow of the Royal Society, and with the help of King Charles II, was granted a master's degree from Oxford.

Nevil Maskelyne FRS FRSE (/ˈmæskəlɪn/; 6 October 1732 – 9 February 1811) was the fifth British Astronomer Royal. He held the office from 1765 to 1811. He was the first person to scientifically measure the mass of the planet Earth. He created The Nautical Almanac, in full the British Nautical Almanac and Astronomical Ephemeris for the Meridian of the Royal Observatory at Greenwich, using Tobias Mayer's corrections for Leonhard Euler's Lunar Theory tables.

The Royal Households of the United Kingdom are the collective departments that support members of the British royal family. The Royal Household (singular) supports the Sovereign. Other members of the royal family who undertake public duties have separate households; they vary considerably in size, from the medium-sized household that supports the Prince and Princess of Wales to those supporting junior working royals (with just a handful of members).

In addition to the royal officials and support staff, the sovereign's own household incorporates representatives of other estates of the realm, including the government, the military, and the church. Government whips, defence chiefs, clergy, scientists, musicians, poets, and artists hold honorary positions within the Royal Household. In this way, the Royal Household may be seen as having a symbolic, as well as a practical, function: exemplifying the monarchy's close relationship with other parts of the constitution and of national life.

John Flamsteed FRS (19 August 1646 – 31 December 1719) was an English astronomer and the first Astronomer Royal. His main achievements were the preparation of a 3,000-star catalogue, Catalogus Britannicus, and a star atlas called Atlas Coelestis, both published posthumously. He also made the first recorded observations of Uranus, although he mistakenly catalogued it as a star, and he laid the foundation stone for the Royal Greenwich Observatory.
