LIVIU LIBRESCU

And his Son.

As Jews worldwide honored on Monday the memory of those who were murdered in the Holocaust, a 76-year-old survivor sacrificed his life to save his students in Monday's shooting at Virginia Tech College that left 33 dead and over two dozen wounded.

Professor Liviu Librescu, 76, threw himself in front of the shooter when the man 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.
