A 1949 immigration document, reads the name of Helmut Gregor, the name which Nazi war criminal Josef Mengele used when he entered in Argentina, shortly after the World War II ended. At the request of the Jewish human right organization Simon Wiesenthal Center, President Nestor Kirchner's administration ordered the opening of all secret documents regarding Nazi war criminals who entered Argentina, such as Mengele, Klaus Altmann and Erich Priebke. They, among no less than 50 Third Reich high officials, found refuge in the country, ruled then by General Juan Domingo Peron. Picture taken August 7, 2003.
