Jacques de Mahieu
A collaborationist in Vichy France, he became an Peronist ideologue in the 1950s, mentor to a Roman Catholic nationalist youth group in the 1960s, and later in life, head of the Argentine chapter of Spanish neo-Nazi group CEDADE.
Early life 
After the liberation of France, he was one of the first to flee to Juan Perón's Argentina through the ratlines organized by Perón and the Vatican. A Naturalized Argentine, he became an ideologue of the Peronist movement, before becoming a mentor to a Roman Catholic nationalist youth group in the 1960s.
Academic career 
Jacques de Mahieu studied at the Universitites of Mendoza and Buenos Aires; he graduated in philosophy, as doctor Honoris Causa of Medicine, doctor in economic sciences, and doctor in political science.
He became a professor of anthropological studies in Buenos Aires as the deputy rector of the Institute of Human Studies (from 1953 to 1955 and again from 1972 to 1976). He also taught economy, ethnography and French at the National University of Cuyo (1948–1955), and at the Universidad del Salvador (1964–1965).
Later life and death 
Mahieu remained in Argentina in his later years. He was photographed with Carlos Menem during the latter's 1989 presidential campaign. Mahieu headed the Argentine chapter of the Spanish neo-Nazi group, CEDADE, until his death in Buenos Aires, in 1990.
Pre-Columbian contact theories 
De Mahieu wrote on pre-Columbian America and esoteric Nazism. He traveled to Paraguay for anthropological studies, and claimed the Guayaki tribes were descendants of the Vikings. He allegedly travelled to Brazil in 1974, where he visited the Sete Cidades park in Piauí and considered it a Viking establishment. His books on the Knights Templar allege they settled in Mexico before Columbus.
Economic and political work 
Beside anthropological interests, Mahieu also wrote about economy and state questions. He wrote a book titled The Communal Economy (1964), which inspired a social and economic project developed in Mendoza. The project ended during the Revolución Libertadora regime, which toppled Juan Perón's government in 1955.
