Seven bridges of königsberg.

Graph theory (the precursor of modern network theory) was invented by the great mathematician Leonhard Euler. In 1735 he was able to prove that it was not possible to walk through the city of Königsberg (now Kaliningrad) crossing each of its seven bridges only once—because of the layout of islands in the Pregel River (fig. 1).Coupy also applied the methods of Euler to the analogous problem of the bridges over the River Seine.
