In 1770, Wolfgang von Kempelen unveiled his Mechanical Turk, a chess-playing automaton. Dressed in a cloak and turban and seated behind a chessboard, the mannequin played chess and executed complex mathematical puzzles. The Turk performed before numerous world leaders before it was revealed to be a hoax; the cabinet beneath the chessboard, which housed the internal mechanism, actually hid a chess master who secretly operated the machine.
