Israeli professor Professor Liviu Librescu

As Jews worldwide honored on Monday the memory of those who were murdered in the Holocaust, a 75-year-old survivor sacrificed his life to save his students in Monday's shooting at Virginia Tech College that left 32 dead and over two dozen wounded.

Professor Liviu Librescu, 76, threw himself in front of the shooter, who had attempted to enter his classroom. The Israeli mechanics and engineering lecturer was shot to death, "but all the students lived - because of him," Virginia Tech student Asael Arad - also an Israeli - told Army Radio.

Several of Librescu's other students sent e-mails to his wife, Marlena, telling of how he blocked the gunman's way and saved their lives, said the son, Joe.

Librescu was sent to a labor camp in Russia as a child and saved by the townspeople. His father was deported by the Nazis.
