Abu Al-Iz ibn Isma'il ibn Al-Razaz Al-Jazari (1136-1206) (أَبُو اَلْعِزِ بْنُ إسْماعِيلِ بْنُ الرِّزاز الجزري) was a scholar, inventor, mechanical engineer, craftsman, artist, matematician and also astronomer from Al Jazira, Mesopotamia, who lived during the Islamic Golden Ages. He is best known for writing the (Book of knowledge of Ingenious Mechanical Devices) in 1206, where he described fifty mechanical devices along with instructions on how to construct them.
Little is known about al-Jazari, and most of that comes from the introduction to his Book of Knowledge of Ingenious Mechanical Devices. He was named after the area in which he was born, Al Jazira, the traditional Arabic name for what was northern Mesopotamia and what is now northwestern Iraq and northeastern Syria, between the Tigris and the Euphrates. Like his father before him, he served as chief engineer at theArtuklu Palace, the residence of the Mardin branch of the Turkish Artuqid dynastywhich ruled across eastern Anatolia as vassals of the Zanghid rulers of Mosul and later Ayyubid general Salahuddin.
Al-Jazari was part of a tradition of craftsmen and was thus more of a practical engineer than an inventor who appears to have been "more interested in the craftsmanship necessary to construct the devices than in the technology which lay behind them" and his machines were usually "assembled by trial an error rather than by theoretical calculation. His “Book of Knowledge of Ingenious Mechanical Devices” appears to have been quite popular as it appears in a large number of manuscript copies, and as he explains repeatedly, he only describes devices he has built himself. According to Mayr, the book's style resembles that of a modern "do-it-yourself" book.
Some of his devices were inspired by earlier devices, such as one of his monumental water clocks, which was based on the Archimedes Principles. He also cites the influence of the Bani Musabrothers for his fountains, Al Asturlabi for the design of a candle clock, and Hibatullah Ibn Al-Hussain (1139) for musical automata. Al-Jazari goes on to describe the improvements he made to the work of his predecessors, and describes a number of devices, techniques and components that are original innovations which do not appear in the works by his precessors.
What interesting about this guy was his vision that beyond and far away from his time until he was also certified by the western specialist. He could be able to create and invent incredible machines that never thought by the people in his time. This man should be an icon to those who wants to think outside the box and became an extraordinary people. I'm proud of the muslims scholar.
