Career
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. In 1828 he provided the first description of a type of acute polyneuritis that would later be known as Guillain–Barré–Strohl syndrome.
Worthington Hooker (1806–1867), in his 1847 book Physician and Patient, gives Chomel cr for the first contemporary usage of the medical axiom, Primum non nocere ("First, do no harm").
