Ibn al-Yasamin
Abu Muhammad 'Abdallah ibn Muhammad ibn Hajjaj ibn al-Yasmin al-Adrini al-Fessi (died 1204), more commonly known as ibn al-Yasmin, was a Maghrebi mathematician. 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”. 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.
