Biography
Born in the city of Ray, near modern Tehran, Abu Bakr al-Razi was a restless intellect who began his career not in medicine but in music and alchemy. His shift to medicine was transformative; he became the chief physician of the Baghdad hospital, where his empirical approach set a new standard. Al-Razi insisted on detailed patient histories and pioneered the concept of ward rounds, authoring a monumental medical encyclopedia, 'Al-Hawi,' that synthesized Greek, Persian, and Indian knowledge with his own clinical notes. Beyond the hospital, his mind roamed freely into philosophy and theology, where he penned provocative arguments questioning the necessity of prophets, a stance that made him a controversial but undeniably bold figure in the Islamic Golden Age. His legacy is that of a skeptical humanist whose work in medicine guided European practice for centuries.
