Abstract
Universities, just as much as towns and cities, are increasingly establishing strong relations with their counterparts abroad. There are now more than 350 universities which operate exchange schemes with universities in the German Federal Republic, and the most active participant in these exchanges is the University of Hamburg. Like the concept of the twin town, the concept of the “twin university” is a specifically postwar development aiming at the creation of regular and, if possible, contract-regulated relations between two institutions as a contribution to international cooperation in the field of science, the prerequisite of which is a solid mutual understanding.
