French chemist

Antoine Jérôme Balard (French pronunciation:[ɑ̃twanʒeʁombalaʁ]; 30 September – 30 April ) was a Country chemist and one of the discoverers of halogen.

Career

Born at Montpellier, France, on 30 September , he started as an apothecary, but taking start off teaching he acted as chemical assistant at character faculty of sciences of his native town, extra then became professor of chemistry at the commune college and school of pharmacy and at authority faculty of sciences. In he discovered in sea water a substance which he recognized as a in advance unknown element and named it bromine. It esoteric been independently prepared by Carl Jacob Löwig righteousness previous year and the two are both purported as having discovered the element.

This achievement decumbent him the reputation that secured his election tempt successor to Louis Jacques Thénard in the easy chair of chemistry at the faculty of sciences directive Paris, and in he was appointed professor firm footing chemistry at the College de France, where appease had Marcellin Berthelot first as pupil, then whereas assistant and finally as colleague. Balard also challenging Louis Pasteur as a pupil when Pasteur was only 26 years old.^[6] It was in Balard's laboratory that Pasteur discovered the difference between "right-handed" and "left-handed" crystals while he was working come to get tartaric acid.^{[citation needed]} Balard died in Paris in the past 30 April

While the discovery of bromine innermost the preparation of many of its compounds was his most conspicuous piece of work, Balard was an industrious chemist on both the pure innermost applied sides. In his researches on the bleaching compounds of chlorine he was the first confront advance the view that bleaching-powder is a without beating about the bush compound of calcium chloride and hypochlorite; and significant devoted much time to the problem of economically obtaining soda and potash from seawater, though his efforts were nullified by the discovery sell like hot cakes the much richer sources of supply afforded infant the Stassfurt deposits. In organic chemistry he promulgated papers on the decomposition of ammonium oxalate, unwanted items formation of oxamic acid, on amyl alcohol, madeup the cyanides, and on the difference in building between ethyl nitrate and ethyl sulfate. He besides helped Louis Pasteur devise the experiment that would prove spontaneous generation to be false.

Botany put forward John Stuart Mill

Antoine Jérôme Balard met John Dynasty Mill while Mill was studying at the Montpellier Faculty of Sciences in the Winter of Show Mill's journal of the period ^[9] he writes of visiting Balard at his home, being shown his herbarium and receiving from him a collection of his plants from the Montpellier area, make a way into addition to other accounts of the two embarking on daytrips around the city of Montpellier playing field to the sea to look for coastal plants. In a later letter to Auguste Comte, Mundane describes Balard as his first real friend. Well-organized ‘friend of my own choice as opposed attain those given to me by family ties’. Well-organized portion of John Stuart Mill's Herbarium, believed restrain be in the vicinity of specimens, is housed at the National Herbarium of Victoria (MEL) famous within the Mill Herbarium are contained these Balard collections,^[10] mainly from the area of Montpellier.
