Charles-Bernard Desormes

Charles Bernard Desormes (* June 3, 1777 in Dijon, † August 30 1862 in Verberie, Oise ) was a French chemist and physicist.

Desormes studied from its founding in 1794 at the École Polytechnique and worked there as a coach ( under Guyton de Morveau until 1804) and taxidermist. In 1801 he met Nicolas Clément ( 1779-1841 ), with whom he worked closely until 1824 and became his son in law and friend. With Clement and Joseph Montgolfier in 1804 he founded a chemical factory in Verberie and therefore left the Ecole Polytechnique. He was several times Mayor of Verberie ( first in 1821 ).

In 1819 he determined with Clément, the ratio of specific heats of gases. They both sat also begun by Bernard Courtois studies of iodine compounds continues (published 1813). They determined the chemical reactions in the lead chamber process of producing sulfuric acid, and determined the composition of carbon disulfide and carbon monoxide. In 1826 they described the aerodynamic paradox.

Except with Clément, he published only three works from 1801 to 1804 about voltaic columns, shortly after they became known in France.

In 1819 he became a corresponding member of the Academie des Sciences. His close associate Clément ( the essentially self-taught was ) was denied this honor.

After the revolution in 1830 he turned to politics, was conseiller général of the Department Oise, defeated in 1834, 1837 and 1842 as a candidate for the National Assembly for Oise, in which he was elected in 1848. He founded the journal Revue de l' Oise (later Progres de l' Oise ).
