Biography

He received a juris doctor from the University of Buenos Aires, and subsequently taught law at the University of Tucumán. Opposed to the 1943 coup d'état, he resigned his post in the university's administrative council, and in 1946, was purged from his academic post by order of the newly elected President Juan Perón, a populist with a strongly anti-communist stance.
