Jean-Baptiste-Alphonse Chevallier

Jean-Baptiste-Alphonse Chevallier (19 July 1793 – 29 November 1879) was a French chemist who contributed to public health through techniques for the detection of adulteration of food and medicine.

Chevallier was born in Langres and moved to Paris at the age of fourteen, working as an assistant for the pharmacist P. F. G. Boullay.

In 1812 he was conscripted into military service and saw action in Germany where he was injured at the Battle of Leipzig (October 16–19, 1813).

He published extensively in journals on public health, forensic and medico-legal matters.

He served as an editor (and prolific contributor) of the Annales d'hygiène publique et de médecine légale from 1831 until his death.
