Ernest Fourneau (4 October 1872 – 5 August 1949) was a French medicinal chemist who played a major role in the discovery of synthetic local anesthetics, as well as in the synthesis of suramin.
He authored more than two hundred scholarly works, and has been described as having "helped to establish the fundamental laws of chemotherapy that have saved so many human lives".Fourneau was a pupil of Friedel and Moureu, and studied in the German laboratories of Ludwig Gattermann in Heidelberg, Hermann Emil Fischer in Berlin and Richard Willstätter in Munich.
He headed the research laboratory of Poulenc Frères in Ivry-sur-Seine from 1903 to 1911.
One of the products was a synthetic local anesthetic that was named "Stovaine" (Amylocaine).
