Imhotep

Imhotep ( fl. c. 2700 BC )
Egyptian architect and scholar. He is usually credited with designing the step pyramid built at Saqqara for the 3rd-dynasty pharaoh Djoser ( c. 2686 – c. 2613 BC ) and, through this, with pioneering the use of hewn stone in building. He was later deified; in Egypt, he was worshipped as the patron of architects, scribes, and doctors, while in Greece he was identified with the god Asclepius.
