The Holocaust Museum Houston presents an outstanding series of lectures dealing with current and historical aspects of anti-Semitism, including a look back at one of the groups most tragically affected by World War II Nazi death camps. Today, Dr. Michael Berenbaum of the American Jewish University in Los Angeles will lead Obligations, Implications and Consequences of Responding to Current Issues. Tomorrow, Mark Weitzman of the Simon Wiesenthal Center will present Anti-Semitism: The Generic Hatred Essays in Memory of Simon Wiesenthal, a historical perspective on anti-Semitism. Wednesday, Gideon Greif, a noted researcher and educator at Yad Vashem in Israel, will give an overview of his book They Wept Without Crying: Testimonies of the Jewish Sonderkommando from Auschwitz. (The Sonderkommando were Jewish internees forced to work in the concentration camp gas chambers.) Finally, on Thursday, Sarah Ogilvie and Scott Miller discuss Refuge Denied: The St. Louis Passengers and the Holocaust, the story of a ship of refugees that attempted to land in Cuba in 1939.
