German Atlantologists have made a considerable contribution to their subject over the past century. In fact, outside the English speaking world the Germans can arguably claim to have contributed most to scientific Atlantology. I think that there is sufficient material to justify a book on German Atlantology on its own. The extent of their influence can be gauged by entering ‘German’ in the Atlantipedia search box.
A recent newsletter from Thorwald C. Franke highlighted the work of German researchers, particularly in the early part of the 20th century. Surprisingly, he did not mention more recent German publications including his own(a) valuable contributions. In 2016 Franke published Kritische Geschichte der Meinungen und Hypothesen zu Platons Atlantis (Critical history of opinions and hypotheses about Plato’s Atlantis), which contains a review of virtually every Atlantis theorist from antiquity until the 20th century. Unfortunately, this 593-page tome is not available in English leaving German readers to be envied for having such a valuable research tool available to them. A summary of his book is available in English(b).
*So it is not without good reason that Franke recently urged serious Atlantis researchers to learn German as it provides access to a lot of valuable research.*
