Louis Le Chatelier

Louis Le Chatelier (born February 20, 1815 in Paris , † November 10, 1873 there ) was a French engineer.

Le Chatelier studied from 1834 to 1836 at the École polytechnique and then at the Ecole des Mines. He then became a mining engineer in the civil service (he later had general supervision of the French mines, Inspecteur General des Mines). He invented a miner's lamp named after him and a method to detect mine gas, which could lead to firedamp explosions .

In 1855, Le Chatelier developed a process to extract aluminum from bauxite and was thus one of the founders of the French aluminum industry, he played a role in the introduction of the Siemens-Martin furnace into the French steel industry and was an important figure in the development of the French railways, for which he was responsible from the state side from 1846. In particular, from 1852 onwards, he was also a technical advisor for the extensive investments in industry and railways made by the brothers Émile Pereire and Isaac Pereire , owners of the Crédit Mobiliere bank. He was also employed internationally, for example for railways in Russia and Spain, and developed railways and industry in northern France. He was also active in state committees. He published several books on railways and locomotive construction.

He had four sons and a daughter. He is the father of the chemist Henry Le Chatelier , the civil engineer Louis Le Chatelier (1853-1928), one of the builders of the Paris Metro and later head of blast furnaces in Caen , and the marine engineer André Le Chatelier (1861-1929), the was known for his studies of steel alloys for marine propulsion. His grandson Robert (born 1930) was the head of the Ugine steel company (now Ugitech).

He is one of the 72 names on the Eiffel Tower and a street in Paris is named after him.
