Born May 6. 1871, in Cherbourg; died Dec. 13. 1935, in Lyon. French organic chemist. Member of the Paris Academy of Sciences (1926).
Grignard taught at the University of Nancy, becoming a professor in 1909. In 1900, together with his teacher, P. Bar-bier, Grignard obtained a solution of etherates of mixed magnesium-halogen-organic compounds and used these compounds in synthesizing many classes of organic compounds. The new method soon became widespread in chemical practice (Grignard reaction). Grignard devoted much attention to working out the nomenclature of organic compounds. He was awarded a Nobel Prize in 1912 (jointly with P. Sabatier).
