‘The Writer’_the oldest example of a computer

Designed in the late 1770s this incredible little robot called simply The Writer, was designed and built by Pierre Jaquet-Droz. He was a Swiss-born watchmaker of the late eighteenth century. He lived in Paris London Geneva, where he designed and built animated dolls, or automata, to help his firm sell watches and mechanical birds.


The Writer has an input device to set tabs that form a programmable memory, 40 cams that represent the read-only programme, and a quill pen for output. Crammed inside is an engineering marvel: 6,000 custom made components work in concert to create a fully self-contained writing machine that some consider to be the oldest example of a computer.
