A copper engraving of the Turk, showing the open cabinets and working parts

The Turk was a hoax that purported to be a chess-playing machine. Constructed and unveiled in 1770 by the Hungarian baron Wolfgang von Kempelen, the mechanism appeared to be able to play a strong game of chess against a human opponent, as well as perform the knight's tour, a puzzle that requires the player to move a knight to occupy every square of a chessboard once and only once. Publicly promoted as an automaton and given its common name based on its appearance, the Turk was a mechanical illusion that allowed a human chess master to hide inside and operate the machine. With a skilled operator, the Turk won most of the games played. The apparatus was demonstrated around Europe and the United States of America for over 80 years until its destruction in 1854, playing and defeating many challengers including statesmen such as Napoleon Bonaparte and Benjamin Franklin.
