Who invented logarithms in mathematics?

  • Al-Khwarizmi
  • John Napier
  • Newton
  • Euclid
Correct Answer: B. John Napier

Detailed Explanation

John Napier, a Scottish mathematician, invented logarithms in the early 17th century. He published his groundbreaking work titled “Mirifici Logarithmorum Canonis Descriptio” (Description of the Wonderful Canon of Logarithms) in 1614. This invention revolutionized mathematics by simplifying complex calculations, particularly in astronomy, navigation, engineering, and physics. Before logarithms, large multiplications and divisions required tedious manual computation. Napier’s method transformed these operations into simpler additions and subtractions by using the properties of exponents — a concept that made mathematical and scientific work faster and more accurate.


Napier’s logarithmic tables provided an efficient way for astronomers and scientists to compute large numerical values, which played a crucial role in the rapid progress of science during the 17th century. His innovation was soon refined and popularized by Henry Briggs, who introduced the common (base-10) logarithms used widely in mathematical tables and slide rules. Together, their work became essential to scientific development long before the invention of calculators and computers.


Key Facts:



  • Inventor: John Napier (1550–1617), Scottish mathematician.

  • Year of Invention: 1614.

  • Book: “Mirifici Logarithmorum Canonis Descriptio.”

  • Purpose: To simplify multiplication and division using addition and subtraction of exponents.

  • Improvement: Henry Briggs later introduced base-10 or common logarithms.


In conclusion, John Napier’s invention of logarithms marked a turning point in mathematical computation. It not only simplified complex arithmetic but also accelerated discoveries in astronomy, physics, and navigation. His innovation laid the groundwork for future computational tools, making him one of the most influential figures in mathematical history.
