Israeli Professor Saved His Students

From the NY Daily News story on Virginia Tech University Prof. Liviu Librescu:

The students in the class dropped to the floor and started overturning desks to hide behind as about a dozen shots rang out, he said.

Then the gunfire started coming closer. Librescu, 77, fearlessly braced himself against the door, holding it shut against the gunman in the hall, while students darted to the windows of the second-floor classroom to escape the slaughter, survivors said.
Mallalieu and most of his classmates hung out of the windows and dropped about 10 feet to bushes and grass below - but Librescu stayed behind to hold off the crazed gunman.

Alec Calhoun, 20, said the last thing he saw before he jumped from the window was Librescu, blocking the door against the madman in the hallway.

He died trying to protect the students.
