The Seven Bridges of Königsberg is a historically notable problem in mathematics. Its negative resolution by Leonhard Euler in 1736 laid the foundations of graph theory and prefigured the idea of topology. The city of Königsberg in Prussia (now Kaliningrad, Russia) was set on both sides of the Pregel River, and included two large islands—Kneiphof and …The puzzle is called The Seven Bridges of Königsberg. It’s based on an actual city, then in Prussia, now Kaliningrad in Russia. The city is divided by a river with two islands in between and, further downstream, the river splits the city again. The problem is deceptively simple: there are (or were, in Euler’s time) seven bridges to connect ...
