Kurt Tank
As in the United States (Operation Paperclip), Argentina also welcomed displaced German scientists such as Kurt Tank and Ronald Richter. Some of these refugees took important roles in Perón's Argentina, such as French collaborationist Jacques de Mahieu, who became an ideologue of the Peronist movement, before becoming mentor to a Roman Catholic nationalist youth group in the 1960s. Belgian collaborationist Pierre Daye became editor of a Peronist magazine. Rodolfo Freude, Ludwig's son, became Perón's chief of presidential intelligence in his first term.
