Born into a Persian family in Khuwarizm (present-day Xorazm Province, Uzbekistan), Muhammad ibn Musa al-Khwarizmi (also known by the Latin form of his name, Algoritmi, circa 780–850 AD, 164–236 AH) was a Muslim mathematician, astronomer, and geographer, and a scholar in the famed House of Wisdom in Baghdad. For other uses, see al Khwārizmī (disambiguation). The word algebra is derived from the name of one of the basic operations with equations (al-ğabr) described in this book.
