Mechanical Turk

The Mechanical Turk was an exhibition machine built by Wolfgang von Kempelen and first presented in 1770. It displayed a figure in Ottoman-style clothing seated at a chessboard and appeared able to play without human help.

The appearance was a carefully constructed deception. A chess player hid inside the cabinet, followed the board position, and controlled the figure through mechanisms. Sliding panels and movable spaces allowed parts of the interior to be shown without exposing the operator.

The Turk was not a computer and did not calculate moves by itself. Its historical importance lies in turning a future question into public theater: whether a machine could reason and play. For decades it stimulated debate about automation, intelligence, and deception long before genuine chess programs existed.
