Maillardet's Automaton.

In 1928, a broken down and badly burned doll-like machine was delivered to the Franklin Institute in Philadelphia. When the institute's machinist finished his repairs, the automaton came to life:

When the repairs were completed and the driving motors were set in motion, the Automaton came to life. It lowered its head, positioned its pen, and began to produce elaborate sketches. Four drawings and three poems later, in the border surrounding the final poem, the Automaton clearly wrote, "Ecrit par L'Automate de Maillardet." This translates to "Written by the Automaton of Maillardet." Amazingly, the first clue of the true history and identity of the machine had come from its own mechanical memory!
