M. Felipoff is referred to as a Russian refugee who lived in Algiers in the early part of the 20th century. He is noted as an astronomer(a) and around 1930 he presented a report to the French Academy of Sciences in which he claimed to have astronomically calculated the exact date of the demise of Atlantis in the Atlantic as 7256 BC(b) . He also maintained that “both the Egyptian and Mexican traditions agree in stating that the island disappeared when the sun was in Cancer.”(c)
Little else is heard of Monsieur Felipoff until a brief mention in The Queensland Times (9 February 1939, p.5) and a later reference in Harold T. Wilkins‘ Secret Cities of Old South America.
