Who or what

Abu al-Qasim Khalaf ibn al-Abbas al-Zahrawi (936–1013), known as Abulcasis, was an Andalusian physician.

His "Al-Tasrif" was a 30-volume medical encyclopedia; volume 30 on surgery was especially influential.

Why it mattered

Al-Zahrawi elevated surgery from a manual craft to a medical science based on anatomy and observation.

He invented or described dozens of surgical instruments still recognizable today.

Key works and moments

He pioneered cauterization, ligatures for controlling bleeding, and surgical removal of bladder stones.

He described procedures for cataract surgery, tooth extraction, amputation, and setting broken bones.

Further detail

The Al-Tasrif covered: medicine, surgery, orthopedics, ophthalmology, pharmacology, nutrition, and childbirth.

His illustrations of surgical instruments became the standard reference for European surgeons.

Legacy

Translated to Latin by Gerard of Cremona, the Al-Tasrif was used at Montpellier and other European medical schools until the 16th century.

Many modern surgical instruments trace their design to al-Zahrawi's originals.
