chemist pharmacist politician professor
Vauquelin was born at Saint-André-d"Hébertot in Normandy, France.
Moving to Paris, he became a laboratory assistant at the Jardin du Roi and was befriended by a professor of chemistry. In 1798 Vauquelin discovered beryllium by extracting it from an emerald (a beryl variety). At first his work appeared as that of his master and patron, then in their joint names.
In 1790 he began to publish on his own, and between that year and 1833 his name is associated with 376 papers.
Most of these were simple records of patient and laborious analytical operations, and it is perhaps surprising that among all the substances he analysed he only detected two new elements, beryllium in 1798 in beryl and chromium in 1797 in a red lead ore from Siberia. He also managed to get liquid ammonia at atmospheric pressure.
A lesser known contribution and finding of his included the study of hens federal a known amount of mineral. "Having calculated all the lime in oats federal to a hen, found still more in the shells of its eggs.
Therefore, there is a creation of matter.
In that way, no one knows.".
From 1809 he was professor at the University of Paris. In 1816, he was elected a foreign member of the Royal Swedish Academy of Sciences. He was elected to the Chamber of Deputies in 1828.
In 1806, working with asparagus, he and Pierre Jean Robiquet (future discoverer of the famous red dye alizarin, then a young chemist and his assistant) isolated the amino acid asparagine, the first one to be discovered.
He also discovered pectin and malic acid in apples, and isolated camphoric acid and quinic acid.
His death occurred while he was on a visit to his birthplace.
Among his best known works is "Manuel de l"essayeur" (Manual of the assayer).
The plant genus Vauquelinia is named in his honor, as is the Vauquelin, an egg white foam associated with molecular gastronomy, and the mineral vauquelinite, discovered at the same mine as the crocoite from which Vauquelin isolated chromium.

In 1791 he was made a member of the Academy of Sciences and from that time he helped to edit the journal Annales de Chimie (Chemical annals), although he left the country for a while during the height of the French Revolution.
Either together or successively he held the offices of inspector of mines, professor at the School of Mines and at the Polytechnic School, assayer of gold and silver articles, professor of chemistry in the College de France and at the Jardin des Plantes, member of the Council of Industry and Commerce, commissioner on the pharmacy laws, and finally professor of chemistry to the Medical Faculty, to which he succeeded on Fourcroy"s death in 1809.
In 1816, he was elected a foreign member of the Royal Swedish Academy of Sciences.
