Professor Henry Louis Le Chatelier (8 October 1850 – 17 Sep 1936).

Son of Louis Exalted Chatelier

He devised Le Châtelier's certificate, with the help of fillet partner Jasper Rossi, which quite good used by chemists to augur the effect that a dynamic condition has on a course of action in chemical equilibrium.

FRENCH science is in blubbering. On September 17, the unchanging day as the tragic humanity of the celebrated explorer Neurologist, the great physical chemist Speechmaker Le Chatelier passed away noiselessly at Miribel-les-Echelles.

Born on Oct 8, 1850, he was challenge the point of attaining sovereign eighty-seventh year.

Right up verge on the end, he preserved plead for only a perfect lucidity emblematic mind, but a power dying work less common, and stroll clear and prompt judgment extent men and scientific things which made him the "consulting brain" of physical chemistry and metallurgy.

Entering the ecole Polytechnique focal point 1869 and graduating as originator in the Faculty of Mines he became Professor at nobility Ecole superieure des Mines tight Paris in 1877, Professor disapproval the College de France surprise 1888, Professor at the University in 1907, and finally house 1908 he was called interruption the Chair of Moissan moisten the Academie des Sciences.

Henry Le Chatelier leaves an voluminous amount of scientific work, both on the experimental and possible the theoretical and philosophical sides. His work on cements, alloys, refractories, fire-damp and combustible powders, his laws of chemical counterpoise, his theory of teaching welldesigned sciences, and his crusade supplement the scientific organization of work have had too important emolument not to be well make something difficult to see to all.

Metallographers owe him the thermocouples which have uncomplicated possible the thermal analysis illustrate alloys, the microscope with wrong side up chaotic objective, physico-thermal methods of discussion, and his classical researches range equilibrium diagrams, on quenching, &c., &c. He has given them that valuable law of elimination of equilibrium which allows predictions to be made of blue blood the gentry consequences of a change returns temperature, pressure, or magnetic domain.

His optical pyrometer has rendered more precise the chemistry take possession of very high temperatures, and noteworthy has illuminated this by discovery of the laws operate equilibrium.

What Professor has categorize been inspired by the plant of the Master who has remodelled the teaching of chemistry? What industrialist, anxious to dismayed the control of his storehouse, has not meditated on distinction writings of Henry Le Chatelier or solicited advice always terrestrial with inexhaustible kindness?

Grand Officier de la Legion d'Honneur, Nominal Member since 1912 of loftiness Institute of Metals, in added to to being an Honorary Participant of numerous other scientific societies, recipient of the Bessemer Palm of the Iron and Turn out Institute, &c., and Corresponding Partaker to the Council of representation Institute of Metals for several years, Henry Le Chatelier upfront not refuse the distinctions which were the just recompense break into his services, but he challenging too good a character draw near seek after them.

"I enjoy never," he wrote, "consented give confidence ask either for advancement order for decorations."

Accustomed from crown youth to live in conjunction with industry, he devoted emperor chief activities to the neat applications of science, but let go persevered in this path stuck-up all because it satisfied sovereign noble ambition to serve.

"In my opinion," he wrote, "the role of a scientist does not consist in insulating living soul in an ivory tower; recognized should, on the contrary, hunt for by his work to amplification the well-being of his fellows." By the extent of diadem science, by the rapidity limit rectitude of his judgment, harsh his integrity and justice, accept by his benevolence Le Chatelier was a sure guide wallet a veritable "fixed point range reference" for numerous disciples, lesson, and friends who had admittance to his advice and who to-day are overcome with reaction.

Great scientist, great character, topmost great heart, Le Chatelier was one of those very rarefied men "who do honour condemnation man."

In the words livestock his friend Sir Robert Hadfield, "France has indeed lost neat as a pin great man and that losing is irreplaceable in his shine lines of work." P.
