Joseph Achille Le Bel

Japanese: ル･ベル（英語表記）Joseph Achille Le Bel

1847‐1930
French chemist. Born in Pécherbronn, Alsace. Studied at the École Polytechnique, served as assistant to AJ Balard (1802-76), and then studied under CA Wurtz. He often conducted research in a dedicated laboratory throughout his life, but was also involved in the petroleum industry. In 1874, at the same time as JH van't Hoff, who studied with him under Wurtz, he independently published a paper on molecular structure and optical activity, proposing the concept of an asymmetric carbon atom. He continued his research in organic chemistry, and contributed to the development of stereochemistry by showing that pentavalent nitrogen atoms can also produce optically active compounds.

フランスの化学者。アルザスのペシェルブロンに生まれる。エコール･ポリテクニクに学び，バラールA.J.Balard(1802‐76)の助手を勤めたのち，C.A.ウルツに師事した。生涯専用の研究室で研究を行うことが多く，かたわら石油工業のしごとにもたずさわった。1874年ウルツのもとでともに学んだJ.H.ファント･ホフと同時，独立に分子構造と光学活性についての論文を発表，不斉炭素原子の概念を提唱。その後も有機化学の研究を続け，5価の原子価をもつ窒素原子も光学活性な化合物を生じることを示すなど，立体化学の発展に貢献した。
