The German Society for Electron Microscopy is a learned society founded in 1949 in Düsseldorf, Germany. Ernst Brüche suggested that an association dedicated to electron microscopy be formed to coordinate German work. In the immediate post-World War II period, there were three German centers of research on electron microscopes: in Berlin under Ernst Ruska, in Mosbach under Brüche, and in Düsseldorf under Bodo von Borries.
