Tischner, Heinrich
Heinrich Tischner was a German Protestant minister for 32 years. He has an extensive website which includes a paper on the possible existence of Atlantis(a). He reviews the theories of a couple of German atlantologists, Otto Muck (Azores), and Jürgen Spanuth (Heligoland) and finds flaws in both theories. While Tischner apparently accepts the existence of Atlantis he is disinclined to offer a theory of his own. Some of his criticisms are now available in English.(b)
