Jean Deruelle (1915-2001) was a French mining engineer, who identified Northern Europe as the cradle of technological development, preceding the great civilisations of the Middle East. He contends that the advances of Northern Europe diffused to the southern nations of the Mediterranean. Deruelle identified Imhotep as an Atlantean immigrant to Egypt, where he contributed to the advances of its civilisation during the 3rd millennium BC and became its chief architect.
More specifically, he places Atlantis in the North Sea, on the Dogger Bank, which is a shoal around 100 km off the northeast coast of England. He has written at least two books on the subject of Atlantis.
A number of maps illustrating his theory are available on a French forum(a).
*Fortunately, an English translation of his theory is available on the de Grazia website(b).*
