Nevil Maskelyne 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 British Nautical Almanac and Astronomical Ephemeris for the Meridian of the Royal Observatory at Greenwich using Johann Tobias Mayer's corrections for Euler's Lunar Theory tables.
John Couch Adams was a British mathematician and astronomer. He was born in Laneast, near Launceston, Cornwall, and died in Cambridge.
Sir George Biddell Airy was an English mathematician and astronomer, and the seventh Astronomer Royal from 1835 to 1881. His many achievements include work on planetary orbits, measuring the mean density of the Earth, a method of solution of two-dimensional problems in solid mechanics and, in his role as Astronomer Royal, establishing Greenwich as the location of the prime meridian.
Henry Kater FRS, FRAS was a British physicist of German descent.
Simon Newcomb was a Canadian–American astronomer, applied mathematician, and autodidactic polymath. He served as Professor of Mathematics in the United States Navy and at Johns Hopkins University. Born in Nova Scotia, at the age of 19 Newcomb left an apprenticeship to join his father in Massachusetts, where the latter was teaching.
Olinthus Gilbert Gregory was an English mathematician, author, and editor.
Jesse Ramsden FRS FRSE was a British mathematician, astronomical and scientific instrument maker. His reputation was built on the engraving and design of dividing engines which allowed high accuracy measurements of angles and lengths in instruments. He produced instruments for astronomy that were especially well known for maritime use where they were needed for the measurement of latitudes and for his surveying instruments which were widely used for cartography and land survey both across the British Empire and outside. An achromatic eyepiece that he invented for telescopes and microscopes continues to be known as the Ramsden eyepiece.
John Hellins FRS was an autodidact, schoolteacher, mathematician, astronomer and country parson.
In celestial navigation, lunar distance is the angular distance between the Moon and another celestial body. The lunar distances method uses this angle, also called a lunar, and a nautical almanac to calculate Greenwich time if so desired, or by extension any other time. That calculated time can be used in solving a spherical triangle. The theory was first published by Johannes Werner in 1524, before the necessary almanacs had been published. A fuller method was published in 1763 and used until about 1850 when it was superseded by the marine chronometer. A similar method uses the positions of the Galilean moons of Jupiter.
The history of longitude describes the centuries-long effort by astronomers, cartographers and navigators to discover a means of determining the longitude of any given place on Earth.
Josefde Mendoza y Ríos (1761–1816) was a Spanish astronomer and mathematician of the 18th century, famous for his work on navigation. The first work of Mendoza y Ríos was published in 1787: his treatise about the science and technique of navigation in two tomes. He also published several tables for facilitating the calculations of nautical astronomy and useful in navigation to calculate the latitude of a ship at sea from two altitudes of the sun, and the longitude from the distances of the moon from a celestial body.
Reuben Burrow was an English mathematician, surveyor and orientalist. Initially a teacher, he was appointed assistant to Sir Nevil Maskelyne, then astronomer-royal, at the Royal Greenwich Observatory and was involved in the Schiehallion experiment. He later conducted research in India, teaching himself Sanskrit and becoming one of the first members of the Asiatic Society. He was the first to measure the length of a degree of an arc of longitude along the Tropic of Cancer. His other major achievements included a study of Indian mathematics although he earned a reputation for being rude and unpolished amid the leading figures in science who came mostly from the upper-class. One commentator called him "an able mathematician but a most vulgar and scurrilous dog."
William Fishburn Donkin FRS FRAS was a British astronomer and mathematician, Savilian Professor of Astronomy at the University of Oxford.
William Marshall Smart was a 20th-century Scottish astronomer.
John Drew was a self-educated English astronomer.
William Lax was an English astronomer and mathematician who served as Lowndean Professor of Astronomy and Geometry at the University of Cambridge for 41 years.
Robert Grant, FRS was a Scottish astronomer.
Samuel Dunn was a British mathematician, teacher, cartographer and amateur astronomer.
Rev William Galbraith was a Scottish mathematician. He taught mathematics and nautical astronomy in Edinburgh, and took an interest in surveying work, becoming an advocate of the extension of the work of triangulating Great Britain.
John Radford Young was an English mathematician, professor and author, who was almost entirely self-educated. He was born of humble parents in London. At an early age he became acquainted with Olinthus Gilbert Gregory, who perceived his mathematical ability and assisted him in his studies. In 1823, while working in a private establishment for the deaf, he published An Elementary Treatise on Algebra with a dedication to Gregory. This treatise was followed by a series of elementary works, in which, following in the steps of Robert Woodhouse, Young familiarized English students with continental methods of mathematical analysis.
