Adriaan Anthonisz (also known as Adriaen Anthonisz of Alcmaer) (1527–1607)[1][2][3] was a Dutch mathematician, surveyor, cartographer, and military engineer who specialized in the design of fortifications. As a mathematician Anthonisz calculated in 1585 the ratio of a circle's circumference to its diameter, which would later be called pi.[2]
