Pierre Jaquet-Droz (French: [ʒakɛ dʁo]; 1721–1790) was a watchmaker of the late eighteenth century. He was born on 28 July 1721 in La Chaux-de-Fonds, in Canton Neuchâtel, at the time part of the Kingdom of Prussia.[1] He lived in Paris, London, and Geneva, where he designed and built animated dolls known as automata to help his firm sell watches and mechanical caged songbirds.

Notable works[edit]

 
Constructed between 1768 and 1774 by Pierre Jaquet-Droz, his son Henri-Louis (1752-1791), and Jean-Frédéric Leschot (1746-1824), the automata include The Writer (made of 6000 pieces), The Musician (2500 pieces), and The Draughtsman (2000 pieces).
His astonishing mechanisms fascinated the kings and emperors of Europe, China, India and Japan.
 
The Turk, also known as the Mechanical Turk or Automaton Chess Player (German: Schachtürke, lit. 'chess Turk'; Hungarian: A Török), was a fake chess-playing machine constructed in the late 18th century. From 1770 until its destruction by fire in 1854 it was exhibited by various owners as an automaton, though it was eventually revealed to be an elaborate hoax.[1]Constructed and unveiled in 1770 by Wolfgang von Kempelen (1734–1804) to impress Empress Maria Theresa of Austria, 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 exactly once.
