George Graham (clockmaker)
George Graham, FRS (7 July 1673, maybe 1675 – 16 November 1751) was an English clockmaker, inventor, and geophysicist, and a Fellow of the Royal Society. He was born in Kirklinton, Cumberland. A Friend (Quaker) like his mentor Thomas Tompion, Graham left Cumberland in 1688 for London to work with Tompion. He later married Tompion's niece, Elizabeth Tompion. Career Graham was partner to the influential English clockmaker Thomas Tompion during the last few years of Tompion's life. Graham is credited with inventing several design improvements to the pendulum clock, inventing the mercury pendulum and also the orrery. He was made Master of the Worshipful Company of Clockmakers in 1722. Between 1730 and 1738, Graham had as an apprentice Thomas Mudge, who went on to be an eminent watchmaker in his own right, and invented the lever escapement, an important development for pocket watches.Harold Bagust, "The Greater Genius?", 2006, Ian Allan Publishing, (page 15) He was widely ...

Transit Instrument
In astronomy, a transit instrument is a small telescope with extremely precisely graduated mount used for the precise observation of star positions. They were previously widely used in astronomical observatories and naval observatories to measure star positions in order to compile nautical almanacs for use by mariners for celestial navigation, and observe star transits to set extremely accurate clocks ( astronomical regulators) which were used to set marine chronometers carried on ships to determine longitude, and as primary time standards before atomic clocks. The instruments can be divided into three groups: meridian, zenith, and universal instruments. Types Meridian instruments For observation of star transits in the exact direction of South or North: * Meridian circles, Mural quadrants etc. * Passage instruments (transportable, also for prime vertical transits) Zenith instruments * Zenith telescope * Photozenith tube (PZT) * zenith cameras * Danjon astrolabe, Zei ...

Westminster Abbey
Westminster Abbey, formally titled the Collegiate Church of Saint Peter at Westminster, is an historic, mainly Gothic church in the City of Westminster, London, England, just to the west of the Palace of Westminster. It is one of the United Kingdom's most notable religious buildings and since Edward the Confessor, a burial site for English and, later, British monarchs. Since the coronation of William the Conqueror in 1066, all coronations of English and British monarchs have occurred in Westminster Abbey. Sixteen royal weddings have occurred at the abbey since 1100. According to a tradition first reported by Sulcard in about 1080, a church was founded at the site (then known as Thorney Island) in the seventh century, at the time of Mellitus, Bishop of London. Construction of the present church began in 1245 on the orders of Henry III. The church was originally part of a Catholic Benedictine abbey, which was dissolved in 1539. It then served as the cathedral of the Dioce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Flamsteed
John Flamsteed (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. Life Flamsteed was born in Denby, Derbyshire, England, the only son of Stephen Flamsteed and his first wife, Mary Spadman. He was educated at the free school of Derby and at Derby School, in St Peter's Churchyard, Derby, near where his father carried on a malting business. At that time, most masters of the school were Puritans. Flamsteed had a solid knowledge of Latin, essential for reading the scientific literature of the day, and a love of history, leaving the school in May 1662.Birks, John L.

Jonas Moore
Sir Jonas Moore, FRS (1617–1679) was an English mathematician, surveyor, ordnance officer, and patron of astronomy. He took part in two of the most ambitious English civil engineering projects of the 17th century: draining the Great Level of the Fens and building the Mole at Tangier. In later life, his wealth and influence as Surveyor-General of the Ordnance enabled him to become a patron and driving force behind the establishment of the Royal Observatory, Greenwich. Origins and early career Jonas Moore was born at Higher White Lee, in Higham, which is in Pendle, Lancashire on 8 February 1617, a son of a yeoman farmer, John Moore. His older brother, also John, had allegedly been bewitched to death in about 1610 by Elizabeth Sothernes (Old Demdike), the most notorious of the Pendle witches. There is no record of Jonas's education but it is likely that he attended Burnley Grammar School, which was only three miles from his home. In 1637, he was appointed clerk to Thomas Bu ...

Richard Towneley
Richard Towneley (10 October 1629 – 22 January 1707) was an English mathematician, natural philosopher and astronomer, resident at Towneley Hall, near Burnley in Lancashire. His uncle was the antiquarian and mathematician Christopher Towneley (1604–1674). Towneley's Catholicism isolated him from some of the key scientific networks of the period, such as the Royal Society, but his individual collaborations were significant and impactful. One of these was with Robert Boyle, helping formulate Boyle's Law, or as Boyle named it, "Mr. Towneley's hypothesis". He also introduced John Flamsteed to the Micrometer (device), micrometer and invented the deadbeat escapement, which became the standard escapement used in precision pendulum clocks and is the main escapement used in pendulum clocks today. Life Richard Towneley was born at Nocton Hall, in Lincolnshire, on 10 October 1629, eldest son of Charles Towneley (1600–1644) and Mary Trappes (1599–1690). The Towneleys were promine ...

Anchor Escapement
In horology, the anchor escapement is a type of escapement used in pendulum clocks. The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each swing, and allows the clock's wheels to advance a fixed amount with each swing, moving the clock's hands forward. The anchor escapement was so named because one of its principal parts is shaped vaguely like a ship's anchor. The anchor escapement was probably invented by British scientist Robert Hooke around 1657, although some references credit clockmaker William Clement, who popularized the anchor in his invention of the longcase or grandfather clock around 1680. When Clement's clock appeared Hooke claimed the invention of the escapement, saying that he had shown a clock with the same escapement to the Royal Society soon after the great fire of 1666. The oldest known anchor clock is Wadham College Clock, a tower clock built at Wadham College, Oxford, in 1670, probably by c ...

Board Of Longitude
The Commissioners for the Discovery of the Longitude at Sea, or more popularly Board of Longitude, was a British government body formed in 1714 to administer a scheme of prizes intended to encourage innovators to solve the problem of finding longitude at sea. Origins Navigators and scientists had been working on the problem of not knowing a ship's longitude. The establishment of the Board of Longitude was motivated by this problem and by the 1707 grounding of four ships of Vice-Admiral Sir Cloudesley Shovell's fleet off the Isles of Scilly, resulting in heavy loss of life. Established by Queen Anne the Longitude Act 1714 named 24 Commissioners of Longitude, key figures from politics, the Navy, astronomy and mathematics. However, the Board did not meet until at least 1737 when interest grew in John Harrison's marine timekeeper. The Board administered prizes for those who could demonstrate a working device or method. The main longitude prizes were: *£10,000 for a method that co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Harrison
John Harrison ( – 24 March 1776) was a self-educated English Carpentry, carpenter and clockmaker who invented the marine chronometer, a long-sought-after device for solving the History of longitude, problem of calculating longitude while at sea. Harrison's solution revolutionized navigation and greatly increased the safety of long-distance sea travel. The problem he solved was considered so important following the Scilly naval disaster of 1707 that the Parliament of Great Britain, British Parliament offered financial rewards of up to £20,000 (equivalent to £ in ) under the 1714 Longitude Act. In 1730, Harrison presented his first design, and worked over many years on improved designs, making several advances in time-keeping technology, finally turning to what were called sea watches. Harrison gained support from the Board of Longitude, Longitude Board in building and testing his designs. Toward the end of his life, he received recognition and a reward from Parliament. Harri ...
