Silbermann, Otto (m)
Otto Silbermann was an investigator who published a short work in the early part of the 20th century on the existence of Atlantis. He covers all the principal theories of his day and finishes off with his conclusion that the Atlantis story had been based on a Phoenician record of a war between Egypt and Libya that had been fought in the Chott region around 2540 BC. He argued that a story such as the Atlantis tale could not have survived oral transmission with all the details recorded by Plato for 9,000 years. I must say that I consider this an extremely valid opinion.*[Nevertheless, a 2015 report from Reid & Nunn highlighted the ability of Australian aborigines to transmit faithfully, a record of events over even greater timespans(a) .]*
Although Silbermann appears to have been German, he published in French and apparently planned a second publication with the title of A Discovered Continent: The History of a Libyan-Phoenician Atlantis, of which I can find no trace.
