Ibn al-Haytham
Abu Ali al-Hasan ibn al-Haytham (965-1040 CE), known in the Latin West as Alhazen, was the greatest optical scientist of the medieval world. His Book of Optics overturned a thousand years of Greek theory about vision, established the camera obscura as a scientific instrument, and introduced an experimental methodology that influenced European science for centuries.
