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.

 

The Jaquet-Droz automata

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.
