Biography

It makes its studies with the Polytechnic school, where he is chemistry teacher of 1809, succeeding Fourcroy, with 1839, replaced by Theophilus-Jules Pelouze.

He is the first holder of the pulpit of physics to the Faculty of Science of Paris, of 1808 to 1832, from which he resigns to occupy the pulpit of organic chemistry and inorganic chemistry of the national Muséum of natural history of 1833 to 1848.

In 1802, it discovers the law of Dilatation gases and, a few years later, the volumetric Lois which bear its name today. These last stipulate that the gases mix between them according to simple volumetric reports/ratios. It makes several improvements to the Baromètre to mercury.

In 1804, it undertakes two rises in balloon in order to study the variations of the terrestrial Magnétisme and the composition of the air with different Altitude S.

In 1806, it is elected member of the Academy of Science, of which he is president in 1822 and 1834.

In 1808, in collaboration with the French chemist Louis Jacques Thénard, Gay-Lussac works with the preparation of the Potassium and the Sodium, and discovers the Bore. The following year, it shows that the Chlore, called then muriatic acid oxygenated, is in fact an element. In 1815, it discovers the Cyanogène, of formula C₂N₂, and the Hydrocyanic acid . In the field of the industrial Chemistry, it improves the manufactoring processes of the sulphuric Acid and the Oxalic acid and develops methods of control by proportioning.

Louis Joseph Gay-Lussac is buried with the Cimetière of the Father-Lachaise.
