The paper considers the development of physics‐teaching at the universities of Königsberg (founded 1544) and Helmstedt (founded 1576). The question is: How many teachers of physics professed Aristotelianism and how long? and why did most of them reject Copernicanismus? The paper suggests that Melanchthon, not only the founder of early German philosophy ‘was also the propounder of a form of, modern Aristotelianism’ which proved very valuable in mediating between theologians and philosophers on the one side and between philosophers and experimentalists (...) on the other side.
