September 17, 1936 – Death of Henry Le Châtelier, famous in chemistry for the principle that bears his name

Despite his engineering background, he preferred to pursue a career as a research professor in chemistry rather than go into industry. In 1887, he was elected director of the General Chemistry department at L'École des Mines in Paris. Until he played until he retired.

He was the successor to Paul Schützenberger as Director of Mineral Chemistry at the Collège de France and, later, at the Sorbonne, he succeeded Henri Moissan.

He investigated:

• The phenomena of combustion;
• The theory of chemical equilibria,
• The measurement of high temperatures and the phenomena of dissociation;
• The properties of metal alloys;
• Iron alloys;
• The methods and general laws of Analytical Chemistry;
• The general laws of Chemical Mechanics;
• Silica and its compounds;
• Some practical applications of the fundamental principles of chemistry;
• The properties of metals and some alloys.

In chemistry, Henry Le Châtelier is known for the chemical principle that bears his name and which is stated:

"If a chemical system in reversible equilibrium experiences a change in concentration, temperature, or pressure, the equilibrium of the system will change to minimize that change."

That is, if the partial pressure of a compound increases to the left of a reaction in equilibrium, it will tend to move to the right to decrease the pressure.
