Thomas Earnshaw
Thomas Earnshaw (4 February 1749 in Ashton-under-Lyne – 1 March 1829 in London) was an English watchmaker who, following John Arnold's earlier work, further simplified the process of marine chronometer production, making them available to the general public. He is also known for his improvements to the transit clock at the Royal Greenwich Observatory in London and his invention of a chronometer escapement and a form of bimetallic compensation balance.Thomas Earnshaw at Encyclopædia Britannica Online.

Ashton-under-Lyne
Ashton-under-Lyne is a market town in Tameside, Greater Manchester, England. The population was 45,198 at the 2011 census. Historically in Lancashire, it is on the north bank of the River Tame, in the foothills of the Pennines, east of Manchester. Evidence of Stone Age, Bronze Age, and Viking activity has been discovered in Ashton-under-Lyne. The "Ashton" part of the town's name probably dates from the Anglo-Saxon period, and derives from Old English meaning "settlement by ash trees". The origin of the "under-Lyne" suffix is less clear; it possibly derives from the Brittonic-originating word ''lemo'' meaning elm or from Ashton's proximity to the Pennines. In the Middle Ages, Ashton-under-Lyne was a parish and township and Ashton Old Hall was held by the de Asshetons, lords of the manor. Granted a Royal Charter in 1414, the manor spanned a rural area consisting of marshland, moorland, and a number of villages and hamlets. Until the introduction of the cotton trade in 1769, Ash ...

Edward Troughton
Edward Troughton FRS FRSE FAS (October 1753 – 12 June 1835) was a British instrument maker who was notable for making telescopes and other astronomical instruments. Life Troughton was born at Corney, Cumberland, the youngest of six children to Francis Troughton, a husbandman on a farm, and his wife, Mary Stable. Originally raised to tend animals, Edward went to London in 1773. He then served an apprenticeship with his uncle, John Troughton (b.c.1716) alongside his elder brother, also John Troughton, and in 1779 he became his business partner and soon established himself as the top maker of navigational, surveying and astronomical instruments in Britain. They were based at 136 Fleet Street in central London. Their shop was called the "Sign of the Orrery". In 1795 he delivered what is now known as the Troughton Equatorial telescope to the Armagh Observatory, a 2-inch aperture refractor telescope mounted equatorially, and its first major instrument since its founding in 179 ...

Matthew Flinders
Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British navigator and cartographer who led the first inshore circumnavigation of mainland Australia, then called New Holland. He is also credited as being the first person to utilise the name ''Australia'' to describe the entirety of that continent including Van Diemen's Land (now Tasmania), a title he regarded as being "more agreeable to the ear" than previous names such as ''Terra Australis''. Flinders was involved in several voyages of discovery between 1791 and 1803, the most famous of which are the circumnavigation of Australia and an earlier expedition when he and George Bass confirmed that Van Diemen's Land was an island. While returning to Britain in 1803, Flinders was arrested by the French governor at Isle de France (Mauritius). Although Britain and France were at war, Flinders thought the scientific nature of his work would ensure safe passage, but he remained under arrest for more than six years. In ...

Josiah Emery
Josiah Emery (probably November 11, 1725 - between July 2 and July 14, 1794) was a watch and clock maker who improved Thomas Mudge's lever escapement in 1785. One of his watches was presented to Lord Nelson who was wearing it when he was killed by a sniper at the Battle of Trafalgar in 1805. Others were made for George III. Biography Emery set up as a watch and clock maker at Cockspur Street, Charing Cross, London. He arrived in England from Geneva in the Republic of Geneva. He was made an honorary member of the London Clockmakers Company. He made good quality cylinder watches and used the pivoted detent escapement. Thomas Mudge had invented the lever escapement in around 1755, giving timepieces their characteristic ‘tick-tock’ sound. Emery was the first watchmaker to use lever escapement and made some improvements. Family Josiah Emery married Anne Jacob (1739-1769) on 4 July 1762 at St Martin in the Fields, Westminster. He had signed the marriage license and its bond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fletcher Christian
Fletcher Christian (25 September 1764 – 20 September 1793) was master's mate on board HMS ''Bounty'' during Lieutenant William Bligh's voyage to Tahiti during 1787–1789 for breadfruit plants. In the mutiny on the ''Bounty'', Christian seized command of the ship from Bligh on 28 April 1789. Some of the mutineers were left on Tahiti, while Christian, eight other mutineers, six Tahitian men and eleven Tahitian women settled on isolated Pitcairn Island, and ''Bounty'' was burned. After the settlement was discovered in 1808, the sole surviving mutineer gave conflicting accounts of how Christian died. Early life Christian was born on 25 September 1764, at his family home of Moorland Close, Eaglesfield, near Cockermouth in Cumberland, England. Fletcher's father's side had originated from the Isle of Man and most of his paternal great-grandfathers were historic Deemsters, their original family surname McCrystyn. Fletcher was the brother to Edward and Humphrey, being the three so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutiny On The Bounty
The mutiny on the Royal Navy vessel occurred in the South Pacific Ocean on 28 April 1789. Disaffected crewmen, led by acting-Lieutenant Fletcher Christian, seized control of the ship from their captain, Lieutenant William Bligh, and set him and eighteen loyalists adrift in the ship's open launch. The mutineers variously settled on Tahiti or on Pitcairn Island. Bligh navigated more than in the launch to reach safety, and began the process of bringing the mutineers to justice. ''Bounty'' had left England in 1787 on a mission to collect and transport breadfruit plants from Tahiti to the West Indies. A five-month layover in Tahiti, during which many of the men lived ashore and formed relationships with native Polynesians, led those men to be less amenable to military discipline. Relations between Bligh and his crew deteriorated after he allegedly began handing out increasingly harsh punishments, criticism, and abuse, Christian being a particular target. After three weeks ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Bounty
HMS ''Bounty'', also known as HM Armed Vessel ''Bounty'', was a small merchant vessel that the Royal Navy purchased in 1787 for a botanical mission. The ship was sent to the South Pacific Ocean under the command of William Bligh to acquire breadfruit plants and transport them to the West Indies. That mission was never completed owing to a 1789 mutiny led by acting lieutenant Fletcher Christian, an incident now popularly known as the mutiny on the ''Bounty''. The mutineers later burned ''Bounty'' while she was moored at Pitcairn Island. An American adventurer helped land several remains of ''Bounty'' in 1957. Origin and description ''Bounty'' was originally a collier, ''Bethia,'' reputedly built in 1784 at Blaydes Yard in Hull, Yorkshire in England. The Royal Navy purchased her for £1,950 on 23 May 1787 (), refit, and renamed her ''Bounty.'' The ship was relatively small at 215 tons, but had three masts and was full-rigged. After conversion for the breadfruit expedit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Indies
The West Indies is a subregion of North America, surrounded by the North Atlantic Ocean and the Caribbean Sea that includes 13 independent island countries and 18 dependencies and other territories in three major archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago. The subregion includes all the islands in the Antilles, plus The Bahamas and the Turks and Caicos Islands, which are in the North Atlantic Ocean. Nowadays, the term West Indies is often interchangeable with the term Caribbean, although the latter may also include some Central and South American mainland nations which have Caribbean coastlines, such as Belize, French Guiana, Guyana, and Suriname, as well as the Atlantic island nations of Barbados, Bermuda, and Trinidad and Tobago, all of which are geographically distinct from the three main island groups, but culturally related. Origin and use of the term In 1492, Christopher Columbus became the first European to record his arri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tahiti
Tahiti (; Tahitian ; ; previously also known as Otaheite) is the largest island of the Windward group of the Society Islands in French Polynesia. It is located in the central part of the Pacific Ocean and the nearest major landmass is Australia. Divided into two parts, ''Tahiti Nui'' (bigger, northwestern part) and ''Tahiti Iti'' (smaller, southeastern part), the island was formed from volcanic activity; it is high and mountainous with surrounding coral reefs. Its population was 189,517 in 2017, making it by far the most populous island in French Polynesia and accounting for 68.7% of its total population. Tahiti is the economic, cultural and political centre of French Polynesia, an overseas collectivity and an overseas country of the French Republic. The capital of French Polynesia, Papeete, is located on the northwest coast of Tahiti. The only international airport in the region, Faaā International Airport, is on Tahiti near Papeete. Tahiti was originally settled by Pol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breadfruit
Breadfruit (''Artocarpus altilis'') is a species of flowering tree in the mulberry and jackfruit family (Moraceae) believed to be a domesticated descendant of ''Artocarpus camansi'' originating in New Guinea, the Maluku Islands, and the Philippines. It was initially spread to Oceania via the Austronesian expansion. It was further spread to other tropical regions of the world during the Colonial Era. British and French navigators introduced a few Polynesian seedless varieties to Caribbean islands during the late 18th century. Today it is grown in some 90 countries throughout South and Southeast Asia, the Pacific Ocean, the Caribbean, Central America and Africa. Its name is derived from the texture of the moderately ripe fruit when cooked, similar to freshly baked bread and having a potato-like flavor. The trees have been widely planted in tropical regions, including lowland Central America, northern South America, and the Caribbean. In addition to the fruit serving as a staple fo ...

Guinea (British Coin)
The guinea (; commonly abbreviated gn., or gns. in plural) was a coin, minted in Great Britain between 1663 and 1814, that contained approximately one-quarter of an ounce of gold. The name came from the Guinea region in West Africa, from where much of the gold used to make the coins was sourced. It was the first English machine-struck gold coin, originally representing a value of 20 shillings in sterling specie, equal to one pound, but rises in the price of gold relative to silver caused the value of the guinea to increase, at times to as high as thirty shillings. From 1717 to 1816, its value was officially fixed at twenty-one shillings. In the Great Recoinage of 1816, the guinea was demonetised and the word "guinea" became a colloquial or specialised term. Although the coin itself no longer circulated, the term ''guinea'' survived as a unit of account in some fields. Notable usages included professional fees (medical, legal, etc.), which were often invoiced in guineas, and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Admiralty
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Great ...
