Joseph Achille Le Bel, French Organic Chemist

Joseph Achille Le Bel (January 21, 1847 - August 6, 1930) was a French organic chemist who showed that carbon compounds which are chemically identical can be structurally different. He is best known for his work in stereochemistry. Le Bel was educated at the École Polytechnique in Paris. In 1874 he announced his theory outlining the relationship between molecular structure and optical activity. This discovery laid the foundation of the science of stereochemistry, which deals with the spatial arrangement of atoms in molecules. This hypothesis was put forward in the same year by the Dutch physical chemist Jacobus Henricus van 't Hoff and is currently known as Le Bel-van't Hoff rule. Le Bel wrote Cosmologie Rationelle (Rational Cosmology) in 1929. Le Bel spent the rest of his career between his family's factory and a private laboratory. No photographer credited, undated.
