Étienne Ossian Henry
Étienne-Ossian Henry (27 November 1798 in Paris – 26 August 1873) was a French chemist, son of Noël-Étienne Henry (1769–1832), and trained by his father, who was director of the Central Pharmacy of the Parisian hospitals and professor in the School of Pharmacy.[1][2] In 1824, he became director of the chemical laboratory of the Academy of Medicine. He discovered sinapin and studied mineral waters, the milk of various animals, nicotine, and tannin.[3] In 1827, with Auguste-Arthur Plisson, who had studied under his father, he discovered aspartic acid.[4][5]
In 1845, he invented the first true burette for titration, which is a widely used device in analytical chemistry and related fields.[6][7]
Works
His works include:
- Traité pratique d'analyse chimique des eaux minérales (second edition, 1858), with his father
- Mémoiré sur l'analyse organique (1830), with Plisson
- Analyse chimique des eaux qui alimentent les fontaines publiques de Paris (1848), with Boutron-Gharland
- A translation of the Codex Medicamentarius (1827), with Ratier

From p. 218: "AC est un tube de verre d'une longuere de 60 centimètres environ, et d'un diamètre de 4 millimètres à peu près. En A se trouve un entonnoir de verre soudé ou adapté à volunté; et en B un petite robinet en cuivre terminé par un tube capillaire. Ce robinet s'adjuste au tube par un bon bouchon et avec de la cire à cacheter. Le tube AB est fixé par deux crochets au long d'une échelle inscrite sur une planche, et cette échelle est divisé en 100 parties égales. Le tout est supporté par un pied qui permet de placer le tube AB au-dessus du vase M contenant le sel de potasse à essayer." (AC is a glass tube [that's] about 60 cm. long, and nearly 4 mm. in diameter. At A, a glass funnel is joined or fitted as desired; and at B [there is] a small copper valve ending with a capillary tube. This valve is fitted to the tube by a good cap and with sealing wax. The tube AB is fixed by two brackets along a scale [that's] inscribed on a plate, and this scale is divided into 100 equal parts. The whole is supported by a base that permits placing the tube AB above a vase M containing the potassium salt to be assayed.)
