Michel Eugène Chevreul

Michel Eugène Chevreul was a French chemist whose work contributed to significant developments in science, medicine, and art. Chevreul's early work with animal fats revolutionized soap and candle manufacturing and led to his isolation of the heptadecanoic (margaric), stearic, and oleic fatty acids. In the process, Chevreul became the first scientist to define the concept of a chemical compound and the first to formally characterize the nature of organic compounds; he is consequently considered a founder of modern organic chemistry.
