A physician and philosopher working in the Arab world of the ninth and tenth centuries, regarded as the founding figure of medieval Jewish Neoplatonism. His medical and philosophical treatises, written in Arabic, were translated into Hebrew, Latin, and Spanish and entered the curriculum of European universities by the early 1200s — required reading for physicians for the rest of the Middle Ages, centuries after his death around 932.
