The earliest known use of the Greek letter π to represent the ratio of a circle's circumference to its diameter was by Welsh mathematician William Jones in his 1706. It has been speculated that pi was chosen because it is the first letter in the word "periphery." It caught on after being popularized by Euler in 1736.
