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]
His son was Emmanuel-Ossian Henry (1826-1867).[8][9][10]
