Abstract. In an example of Enlightenment 'engaged research' and public intellectual practice, Euler established the basis of topology and graph theory through his solution to the puzzle of whether a stroll around the seven bridges of 18th-century Königsberg (Kaliningrad) was possible without having to cross any given bridge twice.The Bridges of Königsberg.
