About Henry Louis Le Chatelier
Henry Louis Le Chatelier was a French chemist of the late 19th and early 20th centuries. He devised Le Chatelier's principle, used by chemists to predict the effect a changing condition has on a system in chemical equilibrium. In chemistry, Le Chatelier is best known for his work on his principle of chemical equilibrium, Le Chatelier's principle, and on varying solubility of salts in an ideal solution. In the first issue of La revue de métallurgie, Le Chatelier published an article describing his convictions on the subject, discussing the scientific management theory of Frederick Winslow Taylor. In 1902 Fouché invented a gas welder tool with French patent number 325,403 and in 1910 Picard developed the needle valve.
