Autoperipatetikos
An Autoperipatetikos, or Autoperipatikos, is a doll who walks by means of a clockwork mechanism (originally patented by Enoch Rice Morrison on July 15, 1862) which causes her feet, usually made of pressed metal, to move back and forth. The dolls were made in Germany, France and America, and are supposedly the first mechanical toy patented in America of which there are still existing examples.
