Augustin Roux (French: [ʁu]; 26 January 1726 – 28 June 1776) was a French doctor, encyclopedist and man of letters during the Age of Enlightenment. Roux was born in Bordeaux, where he studied medicine. He received his doctorate in 1750 and then came to Paris where, on the recommendation of Montesquieu, he was able to obtain the financial support that his family had refused him as punishment for not pursuing an ecclesiastical career. His extensive knowledge of chemistry resulted in his appointment as professor of science at the Faculty in 1771.
