Zdzisław Łukaszkiewicz
Judge Zdzisław Łukaszkiewicz was a member of the Main Commission for the Investigation of Nazi Crimes in Poland () upon the conclusion of World War II. The Commission has been replaced, upon the collapse of the Soviet-imposed communism in Poland, with the government-affiliated Institute of National Remembrance (IPN) serving similar purpose at present. Łukaszkiewicz was the author of the first historical research into the Nazi German extermination camps including Majdanek and Treblinka, on the territory of occupied Poland during the genocidal Operation Reinhard of the Holocaust.
