Omer Bartov (Hebrew: עֹמֶר בַּרְטוֹב) is an Israeli-born historian. He is the Samuel Pisar Professor of Holocaust and Genocide Studies at Brown University, where he has taught since 2000. Bartov is a historian of the Holocaust and is considered one of the world's leading authorities on genocide. The Forward calls him "one of the foremost scholars of Jewish life in Galicia."The son of Israel Prize-winning author Hanoch Bartov, Bartov was born in Israel and educated at Tel Aviv University and St. Antony's College, Oxford. As a historian, he is most noted for his studies of the German Army in World War II. Bartov has challenged the popular view that the German Army was an apolitical force that had little involvement in war crimes or crimes against humanity in World War II, arguing that the Wehrmacht was a deeply Nazi institution that played a key role in the Holocaust in the occupied areas of the Soviet Union. He has also characterized Israel's treatment of Palestinians in the occupied territories as apartheid.
