Alexandre Bessmertny (1888-1943) was born in St. Petersburg and later moved to Germany. In 1933, because of his Jewish background, he fled to France and afterwards to Czechoslovakia where he was arrested by the Gestapo in 1939 and executed in Berlin in 1943.
>In 1893, Bessmertny published a short review of August Knotel‘s Atlantis theories. An English translation is available here(a).<
In the 1930’s he wrote about Atlantis in Das Atlantisrätsel and was published in German and also in French, translated by F. Gidon, who also added his own ideas to the text. Bessmertny discussed the various theories in vogue at that period.
