Gabriel Jars
Gabriel Jars (26 January 1732 – 20 August 1769) sometimes confusingly referred to as Antoine-Gabriel Jars but more correctly as Gabriel Jars the younger was a French mining and metallurgical specialist who along with his brother Gabriel Jars the elder (1729-1808) contributed to knowledge on mining with his three volume work ''Voyages métallurgiques'' published posthumously from 1774 to 1781 by his brother Gabriel Jars the elder. The introduction of coke to smelting processes in France was made through his studies of techniques used in England. Jars was born in Lyon in a mining family, son of Gabriel Jars (d. 1770) and Jeanne-Marie Valioud. The family was in the copper business and quarried pyrite near Saint-Bel and Chessy. He was the third son after Antoine-Gabriel (1728-1795), and Gabriel the elder (1729-1808). He also had three sisters. Jars was educated at the Grand College, Lyon (Lycée Ampère) and then went to work with his father in the mining industry. In 1747, the École ...

Pyrite
The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of ''fool's gold''. The color has also led to the nicknames ''brass'', ''brazzle'', and ''Brazil'', primarily used to refer to pyrite found in coal. The name ''pyrite'' is derived from the Greek (), 'stone or mineral which strikes fire', in turn from (), 'fire'. In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. By Georgius Agricola's time, , the term had become a generic term for all of the sulfide minerals. Pyrite is usually found associated with other sulfides or oxides in quartz ...

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its Brit ...
