Ali ibn Sahl Rabban al-Tabari (808–874)
Born 808 CE, died 874 CE.
Ali ibn Sahl Rabban al-Tabari (Persian: علی ابن سهل ربن طبری آملی; c. 838 – c. 870 CE; also given as 810–855 or 808–864 also 783–858), was a Persian Muslim scholar, physician and psychologist, who produced one of the first Islamic encyclopedia of medicine titled Firdaws al-Hikmah ("Paradise of Wisdom"). Ali ibn Sahl spoke Syriac and Greek, the two sources of the medical tradition of Antiquity which had been lost by medieval Europe, and transcribed in meticulous calligraphy. His most famous student was the physician and alchemist Abu Bakr al-Razi (c. 865–925). Al-Tabari wrote the first encyclopedic work on medicine. He lived for over 70 years and interacted with important figures of the time, such as Muslim caliphs, governors, and eminent scholars. Because of his family's religious history, as well as his religious work, al-Tabarī was one of the most controversial scholars.
