Balthazar-Georges Sage
Balthazar-Georges Sage (; 7 May 1740 – 9 September 1824) was a French chemist who was a founder of the Paris Ecole Royale des Mines. He held a powerful position and was influential in preventing advances in chemistry in France by his insistence on supporting outdated ideas, such as the phlogiston theory, in the face of evidence to the contrary provided by his contemporaries who included Antoine Lavoisier. He also opposed reform in chemical naming. Some historians have called him a "false scholar" (''faux savant''). Life and work Sage was born in Paris, the son of a Paris apothecary François and Marie-Ursule des Cloîtres. He was educated the Collége des Quatre Nations and was influenced by the lectures of Abbé Nollet and G. F. Rouelle. He set up a small laboratory at home to repeat experiments and had an accident with mercuric chloride poisoning at the age of 16. He also built up a collection of minerals and published his first work ''Examen chymique de différentes subst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phlogiston Theory
The phlogiston theory is a superseded scientific theory that postulated the existence of a fire-like element called phlogiston () contained within combustible bodies and released during combustion. The name comes from the Ancient Greek (''burning up''), from (''flame''). The idea was first proposed in 1667 by Johann Joachim Becher and later put together more formally by Georg Ernst Stahl. Phlogiston theory attempted to explain chemical processes such as combustion and rusting, now collectively known as oxidation. It was challenged by the concomitant weight increase, and was abandoned before the end of the 18th century following experiments by Antoine Lavoisier and others. Phlogiston theory led to experiments which ultimately concluded with the discovery of oxygen. Theory Phlogiston theory states that ''phlogisticated'' substances contain phlogiston and that they ''dephlogisticate'' when burned, releasing stored phlogiston which is absorbed by the air. Growing plants then absor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antoine Lavoisier
Antoine-Laurent de Lavoisier ( , ; ; 26 August 17438 May 1794), When reduced without charcoal, it gave off an air which supported respiration and combustion in an enhanced way. He concluded that this was just a pure form of common air and that it was the air itself "undivided, without alteration, without decomposition" which combined with metals on calcination. After returning from Paris, Priestley took up once again his investigation of the air from mercury calx. His results now showed that this air was not just an especially pure form of common air but was "five or six times better than common air, for the purpose of respiration, inflammation, and ... every other use of common air". He called the air dephlogisticated air, as he thought it was common air deprived of its phlogiston. Since it was therefore in a state to absorb a much greater quantity of phlogiston given off by burning bodies and respiring animals, the greatly enhanced combustion of substances and the greater e ...

Jean-Antoine Nollet
Jean-Antoine Nollet (; 19 November 170025 April 1770) was a French clergyman and physicist who did a number of experiments with electricity and discovered osmosis. As a deacon in the Catholic Church, he was also known as Abbé Nollet. Biography Nollet studied humanities at the Collège de Clermont in Beauvais, starting in 1715. He completed a master's degree in the Faculty of Theology at the University of Paris in 1724. He was ordained a deacon in the Catholic Church in 1728, but suspended his clerical career. However he used the title of Abbé throughout his life. Nollet was particularly interested in the new science of electricity. He joined the Société des Arts in 1728, an association which was reestablished from a previous version which ended in 1723. Formed under the patronage of Comte de Clermont, the Société focused on applying natural philosophy to practical arts. This association gave Nollet the opportunity to come into contact with important natural philosophers. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guillaume-François Rouelle
Guillaume François Rouelle (, 15 September 1703 – 3 August 1770) was a French chemist and apothecary. In 1754 he introduced the concept of a base into chemistry as a substance which reacts with an acid to form a salt). He is known as ''l'Aîné'' (the elder) to distinguish him from his younger brother, Hilaire Rouelle, who was also a chemist and known as the discoverer of urea. He started a public course in his laboratory in 1738 where he taught many students among whom were Denis Diderot, Antoine-Laurent de Lavoisier, Joseph Proust and Antoine-Augustin Parmentier. He was elected a foreign member of the Royal Swedish Academy of Sciences in 1749. Why bases for neutral salts were called bases The modern meaning of the word "base" and its general introduction into the chemical vocabulary are usually attributed to the French chemist, Guillaume-François Rouelle (1703–1770), who used the term "Base" in a memoir on salts written in 1754 (see The Origin of the Term "Base" by Wil ...

Louis XV
Louis XV (15 February 1710 – 10 May 1774), known as Louis the Beloved (french: le Bien-Aimé), was King of France from 1 September 1715 until his death in 1774. He succeeded his great-grandfather Louis XIV at the age of five. Until he reached maturity (then defined as his 13th birthday) on 15 February 1723, the kingdom was ruled by his grand-uncle Philippe II, Duke of Orléans, as Regent of France. Cardinal Fleury was chief minister from 1726 until his death in 1743, at which time the king took sole control of the kingdom. His reign of almost 59 years (from 1715 to 1774) was the second longest in the history of France, exceeded only by his predecessor, Louis XIV, who had ruled for 72 years (from 1643 to 1715). In 1748, Louis returned the Austrian Netherlands, won at the Battle of Fontenoy of 1745. He ceded New France in North America to Great Britain and Spain at the conclusion of the disastrous Seven Years' War in 1763. He incorporated the territories of the Duchy of Lorr ...

1740 Births
Year 174 ( CLXXIV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Gallus and Flaccus (or, less frequently, year 927 '' Ab urbe condita''). The denomination 174 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

18th-century French Chemists
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.
