Ismail al-Jazari

Ismail al-Jazari was a polymath and mechanical engineer working under the Artuqid Dynasty in Jazira, Mesopotamia. In 1206 he completed The Book of Knowledge of Ingenious Mechanical Devices, a technical manual describing fifty inventions with full construction instructions. Among them was the elephant clock, a water-driven timekeeping automaton that became one of his signature works. The manuscript preserved engineering knowledge that would ripple forward through centuries, eventually casting al-Jazari as an ancestor of modern robotics and mechanical design.
