Henri-François Gaultier de Claubry

Following the discovery of iodine in 1811, he examined its properties along with Jean-Jacques Colin (1784-1865) and identified its ability to react with starch in 1814.

After beginning studies in medicine, he shifted to research and began to apprentice in the pharmacies of Pelletier and Boudet and at the Hôpital de la Charité before joining the laboratory of Gay Lussac at the École Polytechnique.

The iodine–starch test was first described in 1814 by Gaultier de Claubry and Jean-Jacques Colin,[1] and independently by Friedrich Stromeyer the same year.

[4] His work was a critique of the method of Berzelius in which he had disregarded physical forms, depending only on chemical composition and proportions.

Gaultier de Claubry was also involved in public health after being elected to the Conseil d'Hygiène of the Department of the Seine in 1825 and worked particularly on the testing and examination of products for adulteration, hygiene and disinfection.
