Miguel Serrano (1917-2009) was a former Chilean diplomat in which capacity he was appointed ambassador to India from 1953 until 1962. He was also an unrepentant nazi sympathiser since 1939 and over time he developed what became known Esoteric Nazism, which continues to have support particularly in his native Chile, where there are still substantial numbers of Nazi followers(a).
*Joscelyn Godwin relates[789.126] how Serrano claimed that “the Germans also found there was a way of communication with the Hollow Earth and its secret cities, where the First Hyperboreans had taken refuge from the disaster that reversed the Poles. There a secret base was prepared during the war years, and thither Adolf Hitler escaped in a vimana (flying saucer plane) to direct the “esoteric war” to this day.”*
The spitfirelist website notes that when “Serrano returned to Chile after the Pinochet coup in 1973. Finding the regime unsympathetic to his ideas, he adopted “the role of intellectual gadfly“. In May 1984, Serrano gave the Nazi salute at the funeral in Santiago of SS Colonel Walter Rauff. He convened a rally in Santiago on 5 September 1993, in honor of Rudolf Hess, and in memory of the 62 young Chilean Nazi supporters who were shot dead while occupying a social security building during an abortive coup in 1938. “(c)
Two books by the Chilean historian, Rafael Videla Eissmann, are concerned with Serrano’s views on Atlantis. Many of his other works, mainly in Spanish, are available as pdf files(b).
