On 6 November 1939 , as a part of Sonderaktion Krakau operation , the Nazis arrested professors of Cracow universities who later were executed or sent to concentration camps . Among them were four professors of the academy : Arnold Bolland , Zygmunt Sarna , Walenty Winid and Albin Żabiński , as well as many professors of other universities who were running some classes at the academy . Two buildings of the school were seized , and numerous library books and documents were lost . Classes continued surreptitiously throughout the war , until the school was able to reopen in 1945 . The school was nationalized in 1950 and renamed as Higher School of Economics ( '' Wyższa Szkoła Ekonomiczna '' )
