Jaquet-Droz automata

The Jaquet-Droz automata, among all the numerous automata built by the Jaquet-Droz family, refer to three doll automata built between 1768 and 1774 by Pierre Jaquet-Droz, his son Henri-Louis, and Jean-Frédéric Leschot: the musician, the draughtsman and the writer. The dolls are still functional, and can be seen at the Musée d'Art et d'Histoire of Neuchâtel, in Switzerland. They are considered to be among the remote ancestors of modern computers.
