The principal goal of the Institut für Deutsche Ostarbeit (IDO, Institute of German Work in the East) which replaced the Jagiellonian University in 1940 during Nazi occupation, was the separation of ethnic groups and the segregation of the conquered population. A series of eugenic studies were conducted and documented by the new Nazi authorities. This exhibit by Dorota Nieznalska displays the historical photographs of highlanders from the Podhale region and the Lemko ethnic group taken by the Nazis during those studies. The work is a beautiful example of historical empathy. It evokes the memory of those who have fallen into oblivion and warns against creating hierarchic rankings of ethnicity. It also bestows the status of sacrificial victims to people subjected to such segregation.
