Muhammad ibn Musa al-Khwarizmi
Muhammad ibn Musa al-Khwarizmi (c. 780–850) was a Persian mathematician born in present-day Uzbekistan. He was active in Baghdad, and wrote the first real standard works in arithmetic and equation theory.
These books in the original language, and its translations into Latin 300 years later, came to exert an incomparable influence on the development of Islamic and early Western mathematics.
Al-Khwarizmi introduced in his arithmetic the "Indian" numbers 1-9 and 0, and the decimal position system, while describing the basic arithmetic operations with decimal integers and decimal or sixagesimal fractions. The medieval name algorithm of such textbooks and the modern term algorithm of a well-defined, finite sequence of mathematical operations have their names after al-Khwarizmi.
