Nils Olof Bergquist (1897-1989) was a Swedish engineer with an interest in ancient history. In 1954 he published The Moon Puzzle^[786]  which describes a very close encounter of the earth with a large extraterrestrial body some millions of years ago. As it grazed the earth it caused the ejection of a large mass from what is now the Pacific Ocean. This mass became our Moon.

In 1971 he published, in Swedish, Ymdogat-Atlantis^[785]which looked at Atlantis in the light of Norse mythology. He also studied The Oera Linda Book and in the end endorsed the Dogger Bank as the most likely location of Atlantis.
