"But from our standpoint, the group (the physiocrats) has actually dwindled down to one man who is seen by all economists as one of their greatest scientists: François Quesnay" - according to Joseph A. Schumpeter in his monumental "History of Economic Analysis." And Horst Claus Recktenwald writes: "The application of the circulation principles also in economics has made the Frenchman immortal." François Quesnay (1694 -1774) has changed the world with just one single work. In 1758, he published his "Tableau economique," which for the first time showed the interdependence of the flows of money and goods. This work can be equated with the hour of birth for the Physiocratic School - and many economists see it as the beginning of modern economic policy. Starting in September 1767, Quesnay held a course on economic arithmetic; this was soon followed by the publication of his work "Physiocracy" - a collection of selected writings that was edited by his friend and student Dupont de Nemours. The work was published in two parts with continuous pagination in Leiden and by Merlin in Paris.
