Henry Louis Le Châtelier Biography (1850-1936)

Nationality: French
Gender: Male
Occupation: chemist

Henry Louis Le Châtelier grew up in a family steeped in scientific andtechnological traditions. Young Henry's relatives and close family friends included engineers and scientists involved in lime and cement production, railway construction, mining, and aluminum and steel manufacturing. France's leading chemists often visited the Le Châtelier home, and all of the Le Châtelier children pursued science-related careers. In later life, Le Châtelier said that his family had strongly influenced his research pursuits.

After interrupting his studies to serve as an army lieutenant in the Franco-Prussian War of 1870-71, Le Châtelier returned to college at the École Polytechnique and earned a degree in science and engineering in 1875. Two years later, he became a chemistry professor at the École des Mines, where he began research on cements, ceramics, and glass. Some of his experiments with cements required the measurement of very high temperatures, for which the equipment available at t

Louis Le Chatelier (20 February 1815 – 10 November 1873) was a French chemist and industrialist who developed a method for producing aluminium from bauxite in 1855. His son was chemist Henry Louis Le Chatelier. His name is inscribed on the Eiffel tower.^[1]^[2]

Le Chatelier and his wife Louise Madeleine Élisabeth Durand (1827–1902) had seven children. One was Alfred Le Chatelier (1855–1929), who joined the army. Alfred later became a ceramicist and then held the chair of Muslim sociology in the Collège de France for many years.

Henri Louis Le Chatelier

(1850–1936) French chemist

Le Chatelier was born in Paris, the son of the inspector-general of mines for France. He himself began studying mining engineering, before becoming professor of chemistry at the School of Mines in 1877. He later became professor of mineral chemistry at the Collège de France and finally took the chemistry chair at the Sorbonne in 1907.

He was particularly interested in metallurgy, cements, ceramics, and glass, and his studies of flames led him to study heat and its measurement.

He made a number of contributions to thermometry, the most important of which was his first successful design of a platinum and rhodium thermocouple for measuring high temperatures (1887). This was based on the principle shown by Thomas Seebeck in 1826 that if a circuit is made from two different metals and heated, a current will flow, and that the current is proportional to the temperature difference between the junctions. It was quickly appreciated that the Seebeck effect could be used in a variety of measuring devices; if one junction was placed on t
