Jean Servais Stas

Died 13 Dec 1891 at age 78 (born 21 Aug 1813).Belgian chemist, notable for his accurate determinations of atomic weights. He had worked under the direction of Dumas, with whom he established the atomic weight of carbon. Stas worked assiduously to make more accurate measurements of other atomic weights than had ever been done before. Stas wished to prove the hypothesis of Joseph Proust, that all atoms were conglomerations of hydrogen atoms, though this could not be achieved. Stas was probably the most skilful chemical analyst of the nineteenth century.
