Hélène Metzger, née Brühl, was a French historian and philosopher of science, best known for her pioneering work on the history of chemistry. Born in Chatou on 26 August 1889 into a Jewish family, she studied crystallography and devoted her scholarly life to understanding how scientific ideas developed over time. Although she never held a major academic post, her books and articles earned lasting recognition among historians of science. During the German occupation of France, Metzger was arrested as a Jew in February 1944, interned at Drancy, and deported to Auschwitz in March 1944, where she was murdered. A Stolperstein at 12 rue des Écoles in Chatou commemorates her life and fate.
