Al Jazari was born in 1136 AD, in a place called Al-Jazira (Upper Mesopotamia) in Iraq. He was an inventor, thinker, and engineer, who was considered as the father of engineering of Islamic civilization. His famous book “The Book of Knowledge of Ingenious Mechanical Devices” was a combination of several series of manuscripts of his works. His inventions aimed to help people who are involved in heavy laborious works. In 1976, at the "World of Islam Festival" held in the United Kingdom, a tribute was paid to Al Jazari when the London Science Museum showed a successfully reconstructed working model of his famous water clock.
