The ‘Original’ Inventor of Algebra

Abū ʿAbdallāh Muḥammad ibn Mūsā al-Khwārizmī, earlier transliterated as Algoritmi or Algaurizin, (c. 780, Khwārizm – 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 (systematized and corrected Ptolemy’s data for Africa and the Middle east) 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. His name is also the origin of (Spanish) guarismo and of (Portuguese) algarismo, both meaning digit.
