[The role of world opinion in rescuing Krakow scientists involved in the "Sonderaktion Krakau"].

The Author, participant and victim of the "Sonderaktion Krakau", remembers circumstances of insidious imprisonment of Krakow professors performed on November 6, 1939 by SS Operation Group under command of SS-Stumbannführer Bruno Müller. Based on archival research and relations of the participants of this action, he reconstructs fate of the imprisoned scientists and he analyses activities of political, governmental and diplomatic centers in Poland and particularly abroad towards liberation of the prisoners. A significant role in this international action was played by foreign scientific centers and universities as well as world press agencies. Due to this multinational solidarity, only 20 person out of 183 scientists imprisoned in the Sachsenhausen and Dachau Nazi camps lost their lives. The article is supplemented by a list of publications on the "Sonderaktion Krakau" written by ex-prisoners.
