Biography

The birthday of Abu Abdallah al-Khorezmi is not determined yet. He spent his youth in the cities of Khorezm: in Khiva, Zamahshar and Kat, where he was born, lived, studied and also succeeded in many fields of knowledge. The scientist had lived in Khorasan for some time. He achieved the best results and knowledge when he served as katib – the kind of chancellerian (minister’s adviser) to Abul Hasan Ubaydallah ibn Ahmad al-Utbi (977-982). More likely, Al-Khorezmi often used to be in Bukhara for work. He visited emir’s famous library, where he spoke to many great scientists of that time, including, to his junior contemporary, Ibn Sino. He died in 997.

The Main Scientific Works
