Liviu Librescu, the professor of Romanian origin who died in the massacre at the Virginia Tech saving the life of his students, was honored by the American President George W. Bush in his Thanksgiving speech, the White House website informs.

As a Holocaust survivor, Liviu Librescu witnessed the horrors human nature is capable of but he revealed the sacrifice and goodness a man is capable of, President Bush said.

Liviu Librescu died during the Virginia Tech massacre in which a student opened fire in the Blacksburg campus, killing 33 people and injuring another 28.

Witnesses declared that professor Librescu held the doors in his attempt to stop the aggressor of entering until his students managed to escape through the window.

In his speech Bush evoked several other personalities who marked the US history through their humanitarian or heroic deeds.
