William Playfair
William Playfair (22 September 1759 – 11 February 1823) was a Scottish engineer and political economist. The founder of graphical methods of statistics, Playfair invented several types of diagrams: in 1786 he introduced the line, area and bar chart of economic data, and in 1801 he published what were likely the first pie chart and circle graph, used to show part-whole relations. Playfair has been reported to have been a secret agent for the British Government, although this is a subject of controversy. Biography William Playfair was born in 1759 in Scotland. He was the fourth son (named after his grandfather) of the Reverend James Playfair of the parish of Liff & Benvie near the city of Dundee in Scotland; his notable brothers were architect James Playfair and mathematician John Playfair. His father died in 1772 when he was 13, leaving the eldest brother John to care for the family and his education. After his apprenticeship with Andrew Meikle, the inventor of the thre ...

Forfarshire
Angus (; ) is one of the 32 local government council areas of Scotland, and a lieutenancy area. The council area borders Aberdeenshire, Dundee City and Perth and Kinross. Main industries include agriculture and fishing. Global pharmaceuticals company GSK has a significant presence in Montrose in the east of the county. Angus was historically a province, and later a sheriffdom and county (called Forfarshire or the County of Forfar until 1928), bordering Kincardineshire to the north-east, Aberdeenshire to the north and Perthshire to the west; southwards it faced Fife across the Firth of Tay. The county included Dundee until 1894, when it was made a county of a city. The pre-1894 boundaries of Angus continue to be used as a registration county. Between 1975 and 1996 Angus was a lower-tier district within the Tayside region. The district took on its modern form and powers in 1996, since when the local authority has been Angus Council.

Reverend
The Reverend (abbreviated as The Revd, The Rev'd or The Rev) is an honorific style (form of address), style given to certain (primarily Western Christian, Western) Christian clergy and Christian minister, ministers. There are sometimes differences in the way the style is used in different countries and church traditions. ''The Reverend'' is correctly called a ''style'', but is sometimes referred to as a title, form of address, or title of respect. Etymology The term is an anglicisation of the Latin , the style originally used in Latin documents in medieval Europe. It is the gerundive or future passive participle of the verb ("to respect; to revere"), meaning "[one who is] to be revered/must be respected". ''The Reverend'' is therefore equivalent to ''the Honourable'' or ''the Venerable''. Originating as a general term of respectful address in the 15th century, it became particularly associated with clergy by the 17th century, with variations associated with certain ranks in th ...

The 350px The Scioto Company was a company led by American colonel William Duer, a land speculator, that swindled prospective settlers to the United States by selling worthless deeds of land. Duer worked with a British colleague and several French men to register and organize the company in Paris, France. Ostensibly working with the Ohio Company to purchase land in the Northwest Territory, agents of this institution sold worthless deeds to French people intending to emigrate to the United States. Many were refugees from the excesses of the French Revolution, and the émigrés were made up of minor aristocrats, merchants, artisans and craftsmen. The Scioto Company did not own the land it was selling. History The Scioto Land Company was founded by American speculator Colonel William Duer and others in 1787 af ...

Storming Of The Bastille
The Storming of the Bastille ( ), which occurred in Paris, France, on 14 July 1789, was an act of political violence by revolutionary insurgents who attempted to storm and seize control of the medieval armoury, fortress, and political prison known as the Bastille. After four hours of fighting and 94 deaths, the insurgents were able to enter the Bastille. The governor of the Bastille, Bernard-René Jourdan de Launay, and several members of the garrison were killed after surrendering. At the time, the Bastille represented royal authority in the centre of Paris. The prison contained only seven inmates at the time of its storming and was already scheduled for demolition but was seen by the revolutionaries as a symbol of the monarchy's abuse of power. Its fall was the flashpoint of the French Revolution. In France, 14 July is a national holiday called '' Fête nationale française'' which commemorates both the anniversary of the storming of the Bastille and the '' Fête de la F� ...

Soho, West Midlands
Soho is an area split between the Birmingham and Sandwell metropolitan boroughs of the West Midlands in England. The area is located on the A41 road. The name is an abbreviation of South House, denoting that it was located to the south of Handsworth. The section of the A41 separating Handsworth from Winson Green is known as Soho Road. Soho expanded dramatically during the 19th century with the construction of numerous houses and factories, and immigration from the Commonwealth was centred on these homes during the 1950s and 1960s. Most of the immigrants who settled in Soho were of Indian origin. Further housebuilding took place by the local council during the 1960s and 1970s. Soho falls partly in the Soho ward of the City of Birmingham and partly in the Soho and Victoria ward of the Borough of Sandwell. Soho ward, Birmingham Until 1911 the part now within Birmingham formed part of Handsworth District, and is now a ward within the council constituency of Ladywood. Demograp ...

Boulton And Watt
Boulton & Watt was an early British engineering and manufacturing firm in the business of designing and making marine and stationary steam engines. Founded in the English West Midlands around Birmingham in 1775 as a partnership between the English manufacturer Matthew Boulton and the Scottish engineer James Watt, the firm had a major role in the Industrial Revolution and grew to be a major producer of steam engines in the 19th century. The engine partnership The partnership was formed in 1775 to exploit Watt's patent for a steam engine with a separate condenser. This made much more efficient use of its fuel than the older Newcomen engine. Initially the business was based at the Soho Manufactory near Boulton's Soho House on the southern edge of the then-rural parish of Handsworth. However most of the components for their engines were made by others, for example the cylinders by John Wilkinson. In 1795, they began to make steam engines themselves at their Soho Foundry ...

James Watt
James Watt (; 30 January 1736 (19 January 1736 OS) – 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. At the time engineers such as John Smeaton were aware of the inefficiencies of Newcomen's engine and aimed to improve it. Watt's insight was to realise that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually, he adapted his engine to produce rot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
