Ibn al-Yasamin

Abu Muhammad 'Abdallah ibn Muhammad ibn Hajjaj ibn al-Yasmin al-Adrini al-Fessi^[1] (Arabic: ابن الياسمين) (died 1204),^[2] more commonly known as ibn al-Yasmin, was a Moroccan mathematician during the Middle Ages. He was born in Fez and received his education in Fez and Sevilla, maybe that’s why some historians refer to him as “al-Ishbili”. Little is known of his personal life except that he was born into a Berber family.^[1][2] He is well known for his crucial contribution in developing Ghūbari numerals (West “Arabic” numerals), which are currently used in most parts of the world.^[2] Besides mathematics, he also became famous in literature, law, and particularly in Andalusian poetry.^[2]
