Ohrdruf was a labor camp that was a sub-camp of the Buchenwald concentration camp during World War II. Ohrdruf was mostly unknown by Americans until President Obama revealed that his great-uncle (the brother of his maternal grandmother) was one of the liberators. General Walker and General Middleton had ordered that as many soldiers as possible should be brought to Ohrdruf to view the camp. The bodies were left out until at least the first week of May, so that visiting soldiers could view them.
Obama had first said that his great uncle had liberated Auschwitz, an understandable mistake that was easily caught by the press because Auschwitz was in what is now Poland and everyone knows that Auschwitz was liberated by Soviet soldiers. Obama quickly corrected his statement and Ohrdruf became famous.
