Which Muslim mathematician introduced the idea of logarithms?

Al-Khwarizmi was a celebrated Muslim mathematician, astronomer, and geographer of the 9th century whose pioneering work laid the foundation of modern mathematics. Although the formal development of logarithms came centuries later, Al-Khwarizmi’s contributions to algebra and numerical computation provided the conceptual basis that influenced later mathematicians, including those who developed logarithmic systems. His work on systematic problem-solving, equation balancing, and algorithmic calculation was revolutionary and gave rise to the very term “algorithm,” derived from the Latin form of his name, Algoritmi.

Al-Khwarizmi’s most famous book, Kitab al-Jabr wal-Muqabala (“The Compendious Book on Calculation by Completion and Balancing”), introduced algebra as a distinct mathematical discipline. His clear explanations of numerical methods and proportional reasoning helped later European scholars understand advanced arithmetic, paving the way for logarithmic concepts that simplify complex multiplication and division into addition and subtraction processes. His works were translated into Latin during the 12th century and became a cornerstone of European mathematics for centuries.

Key Facts:

• Full Name: Muhammad ibn Musa al-Khwarizmi


• Era: 9th century (House of Wisdom, Baghdad)


• Main Contribution: Founder of algebra and algorithmic computation


• Legacy: His methods inspired later mathematical advances including logarithmic calculation


• Book: “Kitab al-Jabr wal-Muqabala” — the root of the word “algebra”

In conclusion, Al-Khwarizmi’s genius established the intellectual foundation upon which later mathematicians built the concept of logarithms. His analytical methods bridged the ancient and modern worlds, making him one of the most influential figures in the history of science and mathematics.
