I wish to present my on-going research on another case I work on, Helmstedt 1620-1681. During this period, the University of Helmstedt was one of the most important ones in Germany. The university opened officially in 1576 and closed definitely in 1810. Studying the life at the university and the city is interesting from the point of view of privacy because it was religiously liberal by the days’ standards and formed a closed community with its own laws inside the city. This provoked many tensions. The production of knowledge is one of our foci, and here the interesting part is the relation between private lectures and public lectures, private lives and public lives of professors, and the publication or dissemination of novel ideas.
