History of Hex
The game was first invented by the Danish mathematician Piet Hein. The first article describing the game, which Piet Hein called Polygon, appeared in the Danish newspaper Politiken on 26 December 1942. In 1948 the game was discovered independently by the mathematican John Nash. Nash's fellow players at first called the game Nash. According to Martin Gardner, some of the Princeton University students also referred to the game as John, because it was often played on the hexagonal tiles of bathroom floors. However, this story is, according to Jack van Rijswijck, unfortunately apocryphal. In 1952 Parker Brothers marketed a version. They called their version "Hex" and the name stuck.
