🎎Automatons {mechanical dolls that are self-operating} Morris Museum, NJ 

The Morris Museum in Morristown , NJ.
It has the Guinness Collection of Mechanical Musical Instruments and Automata.
Automaton is a mechanical object, either functional (such as a clock) or decorative (such as a miniature singing bird), that is self-operating. Devices set in motion by water, falling weights, and steam were in use in the 1st century. Decorative mechanical objects were made for ecclesiastical use and table ornaments in the Middle Ages and Renaissance. Spectacular fountains and waterworks can be seen in 16th-century Italian gardens; elaborate mechanical devices were popular in the 18th-19th century. Except for some works by Carl Fabergé, the production of expensive automatons virtually ceased by the 20th century.
