Euler was able to prove that such a route did not exist, and in the process began the study of what was to be called graph theory. The puzzle, which baffled the residents of Königsberg was this: Was it possible to pick a starting point in the town and find a walking route which would take them over each bridge exactly once? No one had ever found such a route but did that mean that it did not exist? The problem caught the attention of the great Swiss mathematician, Leonhard Euler. These islands were connected to each other and to the mainland by seven bridges. The Preger River completely surrounded the central part of Königsberg, dividing it into two islands. The good people of Königsberg, Germany (now a part of Russia), had a puzzle that they liked to contemplate while on their Sunday afternoon walks through the village. Leonhardi Euleri Opera Omnia is a compilation of all of Euler’s work and has multiple volumes.The Birth of Graph Theory: Leonhard Euler and the Königsberg Bridge Problem Overview Even after his death, Euler received great respect from the whole of mathematical society especially the Mathematical Association of America.
