I copied this from tumblr:
This famous android was a collaborative effort by two Germans. Clockmaker Peter Kintzing created the mechanism and joiner David Roentgen crafted the cabinet; the dress dates from the 19th century. Automatons were in circulation and aroused much curiosity. Roentgen probably sent the tympanum to the French court and Marie-Antoinette bought it in 1784. The queen, aware of its perfection and scientific interest, had it deposited in the Academy of Sciences cabinet in 1785. The tympanum is a musical instrument that plays eight tunes when the female android strikes the 46 strings with two little hammers. Tradition has it that she is a depiction of Marie-Antoinette.
