Michel Eugene Chevreul, organic chemist

Michel Eugene Chevreul (August 31, 1786 - April 9, 1889) was a French chemist whose work with fatty acids led to early applications in the fields of art and science. He is credited with the discovery of margaric acid and designing an early form of soap made from animal fats and salt. He discovered the composition of stearin, a white substance found in the solid parts of most animal and vegetable fats, and olein, the liquid part of any fat, and to isolate stearic and oleic acids, the names of which he invented. This work led to important improvements in the processes of candle-manufacture. Chevreul was against charlatanism in every form, and a complete sceptic as to the 'scientific' psychical research or spiritualism. Chevreul was also influential in the world of art. He determined that perceived colour was influenced by other surrounding colours leading him to create a classification of colours and chromatic diagram. This led to a concept known as simultaneous contrast. He lived to 102 and was a pioneer in the field of gerontology. His is one of the 72 names inscribed on the Eiffel Tower.

Michel Eugene Chevreul, organic chemist

Traduction automatique: Michel Eugène Chevreul (31 août 1786 - 9 avril 1889) était un chimiste français dont les travaux sur les acides gras ont conduit aux premières applications dans les domaines de l'art et de la science. On lui attribue la découverte de l'acide margarique et la conception d'une forme précoce de savon à base de graisses animales et de sel. Il a découvert la composition de la stéarine, une substance blanche présente dans les parties solides de la plupart des graisses animales et végétales, et de l'oléine, la partie liquide de toute graisse, et a isolé les acides stéarique et oléique, dont il a inventé les noms. Ces travaux ont conduit à d'importantes améliorations dans les procédés de fabrication des bougies. Chevreul était contre le charlatanisme sous toutes ses formes et un sceptique complet quant à la recherche psychique « scientifique » ou au spiritualisme. Chevreul a également eu une influence dans le monde de l'art. Il a déterminé que la couleur perçue était influencée par d'autres couleurs environnantes, ce qui l'a conduit à créer une classification des couleurs et un diagramme chromatique. Cela a conduit à un concept connu sous le nom de contraste simultané. Il a vécu jusqu'à 102 ans et fut un pionnier dans le domaine de la gérontologie. Son nom est l'un des 72 inscrits sur la tour Eiffel
