The Swiss mathematician and teacher Leonhard Euler is credited with popularizing the use of the symbol π (pi) in mathematical notation. He introduced this notation in the 18th century, specifically in his work "Introductio in analysin infinitorum" published in 1748. Euler's use of π to represent the ratio of a circle's circumference to its diameter has since become a standard in mathematics.

Euler's use of π helped standardize the representation of the ratio of a circle's circumference to its diameter, which is fundamental in mathematics. His contributions to various fields of mathematics have left a lasting legacy.
The symbol for pi (π) was first used by the Welsh mathematician William Jones in 1706. He chose the symbol because it is the first letter of the Greek word "periphery," reflecting its connection to the ratio of a circle's circumference to its diameter. The symbol gained popularity after being adopted by the Swiss mathematician Leonhard Euler in the 18th century, solidifying its use in mathematics.
