In one?s career, it is good to look back at the predecessors in the field. Biomedical engineering history is full of hidden treasures, one of whom is Al-Zahrawi, a Muslim surgeon who had a wide reputation in Europe during the Middle Ages. Herein, besides recalling that he was a surgeon, the intent is to spotlight his talent in biomedical engineering. Important contributions in surgical instruments come up readily in a review of his work, contradicting the view some have maintained of him as a mere compiler. He was a true inventor, creating many surgical instruments that were not known in the Greco-Roman era. Quite early, he produced contributions influencing surgical procedures in Europe from the 14th to the 18th centuries. As a problem solver, he was aware of anatomical and physiological problems, and he moved through design, methods of manufacturing, and practical applications. The illustrations of such instruments in his encyclopedic work, Al-Tasrif, reflect his willingness to teach.
