Jacques de Mahieu

Jacques de Mahieu, whose real name was Jacques Girault, (31 October 1915 – 4 October 1990) was a French Argentine anthropologist and Peronist. He wrote several books on esoterism, which he mixed with anthropological theories inspired by scientific racism.

He joined the Action Française at a young age. A collaborationist in Vichy France and member of the Waffen-SS, he fled to Argentina after the liberation of France from the Nazis. He became a 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.
