a French pathologist. He was a professor at the Hôpital de la Charité in Paris, and in 1827 succeeded René Laennec (1781–1826) as chair of clinical medicine of the Faculté de Paris. In 1852 he declined swearing allegiance to Napoleon III, and thus was deemed having resigned his post. Worthington Hooker (1806–1867), in his 1847 book Physician and Patient, gives Chomel credit for the first contemporary usage of the medical axiom, Primum non nocere ("First, do no harm").
