Iran-Persia: Al Khwarizmi, Persian mathematician, astronomer, geographer, Baghdad (c. 780-c. 850). A stamp of the former Soviet Union issued in 1983 to commemorate 1,200 years since his birth

Abu ?Abdallah Mu?ammad ibn Musa al-Khwarizmi, earlier transliterated as Algoritmi or Algaurizin, (c. 780 – c. 850) was a Persian mathematician, astronomer and geographer, a scholar in the House of Wisdom in Baghdad. In the twelfth century, Latin translations of his work on the Indian numerals, introduced the decimal positional number system to the Western world. His Compendious Book on Calculation by Completion and Balancing presented the first systematic solution of linear and quadratic equations in Arabic. In Renaissance Europe, he was considered the original inventor of algebra, although we now know that his work is based on older Indian or Greek sources. He revised Ptolemy's Geography and wrote on astronomy and astrology. Some words reflect the importance of al-Khwarizmi's contributions to mathematics. 'Algebra' is derived from al-jabr, one of the two operations he used to solve quadratic equations. Algorism and algorithm stem from Algoritmi, the Latin form of his name.
