Pierre Vernier is a historical figure best known for his contribution to the field of surveying and mathematics through the invention of the Vernier scale. The Vernier scale is a small, auxiliary scale that allows for precise measurements to be taken with greater accuracy than by using standard measurement scales alone. This invention, which he introduced in the 17th century, facilitates measurement to fractions of a unit, enhancing the precision of instruments such as calipers and theodolites.
