One of the victims at Virginia Tech was Liviu Librescu: A holocaust survivor.
Liviu Librescu, 75, a senior researcher and lecturer in engineering, was a Holocaust survivor. He had immigrated to Israel from Romania with his wife Marlina, also a survivor, in 1978. He was an expert in aeronautics at Tel Aviv University and the Haifa Technion before moving to the United States in 1984....
According to media accounts quoting students, Mr. Librescu and the class heard shooting in a nearby room. The students said their professor blocked the door to prevent the gunman from entering while some students took cover underneath desks and others leaped out from windows.
