James Watt

James Watt (January 19, 1736–August 19, 1819) was a Scottish mathematician and engineer whose improvements to the steam engine were a key stage in the Industrial Revolution.

He was born in Greenock, Scotland, and lived and worked in Birmingham, England. He was a key member of the Lunar Society. Many of his papers are in Birmingham Central Library.

Timeline

  • 1736: Born in Greenock, Scotland
  • 1754: Learned the trade of mathematical-instrument making in London before returning to Glasgow
  • 1763: Repaired a Newcomen steam engine, which started him thinking about ways to improve the engine.
  • 1765: While wandering through the Glasgow Green's "Golf Course", comes upon the idea of a separate condensing chamber for the steam engine.
  • 1767: Surveyor of Forth and Clyde canal.
  • 1769: Patented separate condensing chamber for steam engine.
  • 1774: Started a business in Soho, near Birmingham, with Matthew Boulton to manufacture his improved Watt steam engine.
  • 1781: Converted reciprocal engine motion to rotary motion.
  • 1782: Invented double-acting engine.
  • 1784: Patented a steam locomotive.
  • 1788: Adapted centrifugal governor for use on the steam engine.

Engineering Achievements

Watt adopted the centrifugal governor to regulate the speed of a steam engine. (This was already in use for governing wind and watermills.) He invented the parallel motion linkage to convert circular motion to an approximate straight line motion (of which he was most proud) and the steam indicator diagram to measure steam pressure in the cylinder throughout the working cycle of the engine, so showing its efficiency.

Watt greatly helped the development of the embryonic steam engine into a viable and economic means of power generation. He realised that the Newcomen steam engine was wasting nearly three quarters of the steam energy in heating the piston and chamber. Watt developed a separate condenser chamber which significantly increased the efficiency. Further refinements (insulation of the steam cylinder, the double-acting engine, a counter, an indicator, and a throttle valve) made the steam engine his life's work.

Watt was opposed to the use of high pressure steam, and is held by some to have held back the technical development of the steam engine by other engineers, until his patents expired in 1800. With his partner Matthew Boulton he battled against rival engineers such as Jonathan Hornblower who tried to develop engines which did not fall foul of his 'catch-all' patents. Boulton proved an excellent businessman, and both men eventually made fortunes.

He introduced a unit called the horsepower to compare the power output of steam engines, his version of the unit being equivalent to 550 foot-pounds per second (about 745.7 watts).

Watt also invented several other things, not least a copying device for letters.

Legacy

James Watt's model of the steam engine converted a machine of limited use to one of efficiency and many applications. It was the foremost energy source in the emerging Industrial Revolution, and greatly multiplied its productive capacity. (Without it, humans might have continued to provide power.) It was also essential in later transportation advancements, such as the steamboat and locomotive.

Remembrance

The SI unit of power, the watt, is named after him. So is, at least in part, Edinburgh's Heriot-Watt University.

He is also remembered by the Moonstones, two individual statues, and a statue of him, Boulton and Murdoch by William Bloye, and a school named in his honour, all in Birmingham.

There are 4 colleges named after him in Scotland, James Watt College in Kilwinning (North Ayrshire Campus) and Greenock (2 in Greenock, Finnart Campus and Waterfront Campus) and a campus in Largs.

Matthew Boulton's home, Soho House, is now a museum, commemorating the work of both men.

There are over 50 roads or streets named after him, in the UK.

Daughters:. He is also remembered by the Moonstones, two individual statues, and a statue of him, Boulton and Murdoch by William Bloye, and a school named in his honour, all in Birmingham. The Latin word for blond is "flavus", and "rutilo", meaning 'golden-red' or 'auburn', is the word Tacitus uses for the Germans' hair.

So is, at least in part, Edinburgh's Heriot-Watt University. Charlemagne in later imagery (see Dürer portrait right) is often portrayed with flowing blond hair, due to a misunderstanding of Einhart's Vita caroli Magni (chapter 22) where Charlemagne in his age had canitie pulchra "beautiful white hair" which has been rendered as blond or fair in many translations. The SI unit of power, the watt, is named after him. Even the verbal portrait by Einhard suppresses details that would have been indecorous in this context. (Without it, humans might have continued to provide power.) It was also essential in later transportation advancements, such as the steamboat and locomotive. The images of enthroned Charlemagne, God's representative on Earth, bear more connections to the icons of Christ in Majesty than to modern (or Antique) conceptions of portraiture. It was the foremost energy source in the emerging Industrial Revolution, and greatly multiplied its productive capacity. Charlemagne, as an ideal ruler, ought to be portrayed in the corresponding fashion, any contemporary would have assumed.

James Watt's model of the steam engine converted a machine of limited use to one of efficiency and many applications. The Roman tradition of realistic personal portraiture was in complete eclipse at the time of Charlemagne, where individual traits were submerged in iconic typecastings. Watt also invented several other things, not least a copying device for letters. This was quite an achievement for kings at this time, of whom most were illiterate. He introduced a unit called the horsepower to compare the power output of steam engines, his version of the unit being equivalent to 550 foot-pounds per second (about 745.7 watts). Another interesting note about Charlemagne was that he took a serious effort in his and others' scholarship and had learned to read in his adulthood, although he never quite learned how to write. Boulton proved an excellent businessman, and both men eventually made fortunes. Charlemagne's genealogical tree was quite extensive, and can be traced almost completely up to modern times; among the well known direct descendants of Charlemagne are William Howard Taft, 27th President of the United States, and British actor Christopher Lee.

With his partner Matthew Boulton he battled against rival engineers such as Jonathan Hornblower who tried to develop engines which did not fall foul of his 'catch-all' patents. They were married into houses of nobility and as a result of intermarriages many people of noble descent can indeed trace their ancestry back to Charlemagne. Watt was opposed to the use of high pressure steam, and is held by some to have held back the technical development of the steam engine by other engineers, until his patents expired in 1800. Charlemagne's marriage and relationship politics and ethics did, however, result in a fairly large number of descendants, all of whom had far better life expectancies than is usually the case for children in that time period. Further refinements (insulation of the steam cylinder, the double-acting engine, a counter, an indicator, and a throttle valve) made the steam engine his life's work. However, only a small percentage can actually prove descent from him. Watt developed a separate condenser chamber which significantly increased the efficiency. It is frequently claimed by genealogists that all people with European ancestry alive today are probably descended from Charlemagne.

He realised that the Newcomen steam engine was wasting nearly three quarters of the steam energy in heating the piston and chamber. He was a model knight as one of the Nine Worthies. Watt greatly helped the development of the embryonic steam engine into a viable and economic means of power generation. His canonization by Antipope Paschal III was never recognized by the Holy See. (This was already in use for governing wind and watermills.) He invented the parallel motion linkage to convert circular motion to an approximate straight line motion (of which he was most proud) and the steam indicator diagram to measure steam pressure in the cylinder throughout the working cycle of the engine, so showing its efficiency. Charlemagne himself was accorded sainthood inside the Holy Roman Empire after the 12th century. Watt adopted the centrifugal governor to regulate the speed of a steam engine. One of the great medieval literature cycles, the Charlemagne cycle or the Matter of France, centres around the deeds of Charlemagne's historical commander of the Breton border, Roland, and the paladins who served as a counterpart to the knights of the Round Table; their tales were first told in the chansons de geste.

. Charlemagne enjoyed an important afterlife in European culture. Many of his papers are in Birmingham Central Library. The pan-European nature of Charlemagne's influence is indicated by the origins of many of the men who worked for him: Alcuin, an Anglo-Saxon; Theodulf, a Visigoth; Paul the Deacon, a Lombard; and Angilbert and Einhard, Franks. He was a key member of the Lunar Society. Most of the surviving works of classical Latin were copied and preserved by Carolingian scholars. He was born in Greenock, Scotland, and lived and worked in Birmingham, England. Charlemagne's reign is often referred to as the Carolingian Renaissance because of the flowering of scholarship, literature, art, and architecture.

James Watt (January 19, 1736–August 19, 1819) was a Scottish mathematician and engineer whose improvements to the steam engine were a key stage in the Industrial Revolution. He also spoke Latin and understood some Greek. For the BBC Radio York presenter see James Watt. Charlemagne's mother tongue was the Old High German dialect called Frankish. Watt.. At least one of them, Bertha, had a recognized relationship, if not a marriage, with Angilbert, a member of Charlemagne's court circle. For Ronald Reagan's Secretary of the Interior, see James G. After his death the surviving daughters entered or were forced to enter monasteries.

This article is about the Scottish engineer and inventor. This may have been an attempt to control the number of potential alliances. 1788: Adapted centrifugal governor for use on the steam engine. None of them contracted a sacramental marriage. 1784: Patented a steam locomotive. It is difficult to understand Charlemagne's attitude toward his daughters. 1782: Invented double-acting engine. After Charlemagne's death, continental coinage degraded and most of Europe resorted to using the continued high quality English coin until about 1100.

1781: Converted reciprocal engine motion to rotary motion. These three kingdoms would be the foundations of later France and the Holy Roman Empire. 1774: Started a business in Soho, near Birmingham, with Matthew Boulton to manufacture his improved Watt steam engine. He was succeeded by his only son to survive him, Louis the Pious, after whose reign the empire was divided between his three surviving sons according to Frankish tradition. 1769: Patented separate condensing chamber for steam engine. When Charlemagne died in 814, he was buried in his own Cathedral at Aachen. 1767: Surveyor of Forth and Clyde canal. To enforce loyalty, he set up the system of missi dominici, meaning 'Envoys of the Lord.' In this system, one representative of the church and one representative of the emperor would head to the different counties and every year report back to Charlemagne on their status.

1765: While wandering through the Glasgow Green's "Golf Course", comes upon the idea of a separate condensing chamber for the steam engine. Counts served as judges, administrators, and they enforced capitularies. 1763: Repaired a Newcomen steam engine, which started him thinking about ways to improve the engine. Charlemagne organized his empire into 350 counties, each led by an appointed count. 1754: Learned the trade of mathematical-instrument making in London before returning to Glasgow. Charlemagne applied the system to much of the European Continent, and Offa's standard was voluntarily adopted by much of England. 1736: Born in Greenock, Scotland. During this period, the livre and the sou were counting units, only the denier was a coin of the realm.

pound)— both monetary and unit of weight— which was worth 20 sous (like the solidus, and later the shilling) or 240 deniers (like the denarius, and eventually the penny). He set up a new standard, the livre (i.e. Both he and King Offa of Mercia took up the system set in place by Pippin. Pursuing his father's reforms, Charlemagne did away with the monetary system based on the gold sou.

To avoid frictions with the Eastern Emperor, Charles later called himself not Imperator Romanorum (a title reserved for the Eastern Emperor), but rather as Imperator Romanum gubernans Imperium (Emperor ruling the Roman Empire). Though this, according to the sources, occurred against his intentions, Charles thus became the renewer of the Western Empire, which had expired in the 5th century. In 800, at Mass on Christmas day in Rome, Pope Leo III crowned Charlemagne Imperator Romanorum (Emperor of the Romans). In 797 (or 801?) the caliph of Baghdad, Harun al-Rashid, presented Charlemagne with an Asian elephant named Abul-Abbas (See History of elephants in Europe.).

He dreamed of the reconquest of Spain, but never fully succeeded in this goal. After thirty years of war and eighteen battles, he conquered Saxony, a goal that had been the unattainable dream of Augustus, and proceeded to convert the conquered to Catholic Christianity, using force where necessary. Charlemagne was engaged in almost constant battle throughout his reign. In 774 he deposed their king Desiderius and was himself crowned king of the Lombards, permanently unifying the kingdom of Italy to the Frankish crown.

Shortly after that, he marched against the Lombards in Italy. Carloman died on 5 December 771, leaving Charlemagne the leader of a reunified Frankish kingdom. Charles took the outer parts of the kingdom, bordering on the sea, namely Neustria, Aquitania and the northern parts of Austrasia, while Carloman attained the inner parts, bordering on Italy. On the death of Pippin the kingdom was divided between Charlemagne and his brother Carloman.

Charlemagne was the elder son of Pippin the Younger (714 – 24 September 768, reigned 751 – 768) and his wife Bertrada of Laon (720 – 12 July 783); he was the brother of the Lady Bertha, mother of Roland. The best guesses include April 1, 747, after April 15, 747, or April 1, 748. So at present, it is impossible to be certain of the date of the birth of Charlemagne. Other commentators weighing the primary records have suggested that the birth was one year later, 748.

The birth of an Emperor on Easter is a coincidence likely to provoke comment, but there is no such comment documented in 747, leading some to suspect the Easter birthday was a pious fiction concocted as a way of honoring the Emperor. In that year, April 1 is Easter. Another date is given in the Annales Petarienses, April 1, 747. Second, 742 precedes the marriage of his parents (in 744), yet there is no indication that Charlemagne was born out of wedlock, and he inherited from his parents.

First, the year 742 was calculated from his age given at death, rather than attested with primary sources. Charlemagne's birthday was believed to be April 1, 742, but several factors led to reconsideration of this traditional date. . Today both France and Germany look to him as a founding figure of their respective countries.

His dual role as Emperor - Imperator Augustus - and King of the Franks provides the historical link between the Imperial dignity and the Frankish kingdoms and later Germany. 742 or 747 – January 28, 814) (or Charles the Great, in German Karl der Große, in Latin Carolus Magnus, giving rise to the adjective form "Carolingian"), was king of the Franks from 771 to 814, King of the Lombards since 774, and the renewer of the Western Empire.
