Edgar Dacqué (1878-1945) was a leading German Professor of Palaeontology. We are told by a Dutch website(b) that he thought Atlantis to have been situated on a submarine ridge stretching from Cape Verde to the Caribbean.*This sounds like a revised version of the Atlantic landbridges concept that was popular with some scientists at the end of the 19th and beginning of the 20th centuries.*
It is reported that he supported (1927) the idea of Cape Verde as the site of Atlantis, but I have been unable to confirm this. His adherence to Theosophy coloured his professional writings, for example with his claim that homo sapiens existed at the time of the dinosaurs. Similar ideas are promoted today by other theosophists such as John S. Gordon, who has written two Atlantis related books.
It has been claimed(a) that Dacqué wrote to Hitler in the 1920’s regarding some of his (Dacqué’s) occult ideas.
