Emilio Massera

Emilio Eduardo Massera was an Argentine Naval military officer and a leading participant in the Argentine coup d'état of 1976. In 1981, he was found to be a member of P2, a clandestine Masonic lodge involved in Italy's strategy of tension. Many considered Massera to have masterminded the junta's Dirty War against political opponents, which resulted in over 30,000 deaths and disappearances.
