Political refugees - At the conclusion of events, many participants decided to stay in Argentina or moved elsewhere in South America, rather than face an uncertain future by returning to Europe in the midst of World War II. The players affected included Miguel Najdorf, Paulino Frydman, Gideon Ståhlberg, Erich Eliskases, Paul Michel, Ludwig Engels, Albert Becker, Heinrich Reinhardt, Jiří Pelikán, Karel Skalička, Markas Luckis, Movsas Feigins, Ilmar Raud, Moshe Czerniak, Meir Rauch, Victor Winz, Aristide Gromer, Franciszek Sulik, Adolf Seitz, Chris De Ronde, Zelman Kleinstein, Sonja Graf and Paulette Schwartzmann. Most of them were Jewish and had come to Buenos Aires in August 1939 on the Belgian steamer "Piriapolis". The ship has therefore come to be regarded as the epitome of Noah's Ark for a generation of chess players. Significantly, all members of the German team also chose not to return to Nazi Germany.
