Intellectuals Voltaire, Rousseau, Ben Franklin, Napoleon Bonaparte visited the coffeehouse over the years, where ''the game of Chess is played best'' according to Diderot. There in 1783 Wolfgang von Kempelen brought for public demonstration the chess player automaton: The Turk. The Turk could perform Knight's Tours faster even than the great Francois-Andre Danican Philidor, author of 'Analyse du jeu des Echecs'. Franklin there as signatory to the Treaty of Paris ending American Revolution, lost a game played to the freestanding Turk. Though winning, Philidor was terrified in principle of a chess-playing machine. Savants' articles in the journal for the French Academy of Sciences speculated that the cylinder inside must encode ''sets of preprogrammed chess moves.'' ''As it made each move, the Turk's gloved left hand moved over the board so that it was positioned above a particular chessman. Its fingers would then close to grasp the piece and move it to another square (or off the board entirely). After making each move, the automaton rested its arm on the cushion, at which point the sound of whirring clockwork would cease. The Turk moved its head under certain circumstances during the game. After a move endangering its opponent's Queen, the Turk would nod its head twice; and when placing the King in check, it would nod three times. Every ten or twelve moves Kempelen returned to the left-hand side of the cabinet to wind up the clockwork mechanism.'' --Tom Standage, 'The Turk' 2002 Year 1783 also saw in southern France the first-ever successful demonstration of flight in a hot-air balloon.
