After figuring out what the previous parts were using an "Identification (N)" card, Leonard dived into researching the information mentioned within the card.
Even as a professional in archaeology and cultural relics identification, Leonard didn't know everything. Thankfully, it was the Information Age now, making it much easier than before to find information. Therefore, he quickly found all the public resources about this person online.
Peter Jaquet-Droz was an 18th-century master clockmaker from Switzerland. Apart from creating timepieces, he often crafted lifelike robots.
These robots were either gifted to kings and nobles or exhibited in upper-class society to help his company sell more clocks and mechanical birds.
In the 1770s, Peter and his sons invented some of the world's earliest robots that were powered by clockwork.
