The first person to use the pi (π) symbol was Welsh mathematician William Jones in 1706. He adopted it to represent the ratio of a circle's circumference to its diameter, deriving it from the Greek word "periphery" (περίμετρος). The symbol was later popularized by the mathematician Leonhard Euler in the 18th century, solidifying its use in mathematical literature.
