Jacques Claude Marie Vincent de Gournay (French: [də ɡuʁnɛ]; 28 May 1712, Saint-Malo, Province of Brittany – 27 June 1759, Cádiz), was a French economist, who became an intendant of commerce. Some historians of economics believe that he coined the phrase laissez faire, laissez passer. Evidence was to be found when the French State parted the East India Company privilege (monopoly) on the slave trade. He is also credited with coining the term "bureaucracy". Together with François Quesnay, whose disciple he was, he was a leader of the Physiocratic School.
Gournay's father was Claude Vincent, a merchant in Saint-Malo as well as a secretary to the king. Gournay didn't write much, but had a great influence on French economic thought through his conversations with many important theorists. He became instrumental in popularizing the work of Richard Cantillon in France.
