François Quesnay (fʁɑ̃swa kɛnɛ; 4 June 1694 – 16 December 1774) was a French economist and physician of the Physiocratic school. He is known for publishing the "Tableau économique" (Economic Table) in 1758, which provided the foundations of the ideas of the Physiocrats. This was perhaps the first work attempting to describe the workings of the economy in an analytical way, and as such can be viewed as one of the first important contributions to economic thought. His Le Despotisme de la Chine, written in 1767, describes Chinese politics and society, and his own political support for enlightened despotism.
Quesnay was born at Méré near Versailles, the son of an advocate and small landed proprietor. Apprenticed at the age of sixteen to a surgeon, he soon went to Paris, studied medicine and surgery there, and, having qualified as a master-surgeon, settled down to practice at Mantes. In 1737 he was appointed perpetual secretary of the academy of surgery founded by François Gigot de la Peyronie, and became surgeon in ordinary to King Louis XV. In 1744 he graduated as a doctor of medicine; he became physician in ordinary to the king, and afterwards his first consulting physician, and was installed in the Palace of Versailles. His apartments were on the entresol, whence the Réunions de l'entresol received their name. Louis XV esteemed Quesnay highly, and used to call him his thinker. When he ennobled him he gave him for arms three flowers of the pansy (derived from pensée, in French meaning thought), with the Latin motto Propter cogitationem mentis.
He now devoted himself principally to economic studies, taking no part in the court intrigues which were perpetually going on around him. Around 1750 he became acquainted with Jacques C. M. V. de Gournay (1712–1759), who was also an earnest inquirer in the economic field; and round these two distinguished men was gradually formed the philosophic sect of the Économistes, or, as for distinction's sake they were afterwards called, the Physiocrates.
