Archival Overview
Persian polymath at Baghdad's House of Wisdom who founded algebra (al-jabr), gave his name to the 'algorithm', and introduced Hindu-Arabic numerals and decimal positional notation to the West.
Biographical Record
Muhammad ibn Musa al-Khwarizmi (c. 780–850 CE) was appointed by Caliph al-Ma'mun to the prestigious House of Wisdom (*Bayt al-Hikma*) in Baghdad. His seminal 820 CE treatise, Al-Kitab al-mukhtasar fi hisab al-jabr wal-muqabala ('The Compendious Book on Calculation by Completion and Balancing'), created algebra as an independent mathematical science, giving the discipline its universal name (*al-jabr*).
His Latinized name, Algoritmi, became the root of the word 'algorithm', honoring his step-by-step mathematical procedures. His book on Indian reckoning introduced the digits 0–9, positional value, and the concept of zero to Islamic civilization and medieval Europe, revolutionizing commerce, engineering, and science.
