Charles Bernard Desormes(French:[dezɔʁm];3 June 1777 – 30 August 1862[1]) was a Frenchphysicistand chemist. He determined the ratio of the specific heats ofgasesin 1819. He did this and almost all his scientific work in collaboration with his son-in-lawNicolas Clément(1779–1841). Clément and Desormes correctly determined the composition ofcarbon disulfide(CS2) andcarbon monoxide(CO) in 1801–02. In 1806 they elucidated all the chemical reactions that take place during the production ofsulfuric acidby the lead chamber method, as used in industrial chemistry. In 1813 they made a study of iodine and its compounds.
Desormes was born inDijon,Côte-d'Or.He was a student at theÉcole PolytechniqueinParisfrom 1794, when it opened, and subsequently worked there as a demonstrator. Désormes met Clément at the Ecole Polytechnique 1801, beginning a scientific collaboration that lasted until 1824. He left the Ecole 1804 to establish an alum refinery atVerberie,Oise,with Clément and Joseph Montgolfier, who had earlier pioneered balloon flight. Desormes was elected counsellor for Oise 1830 and in 1848 to the national assembly, in which he sat with themoderate republicans.He died inVerberie.
