An Israeli professor and Holocaust survivor sacrificed his own life to save the lives of countless students during the carnage Monday at Virginia Tech.
Liviu Librescu, 76, blocked the doorway to his classroom with his body and told the students to flee.
He was shot through the door by gunman Cho Seung-Hui, "but all the students lived because of him,” Virginia Tech student Asael Arad said.
Librescu was beginning a class on solid mechanics when he and his students heard gunshots in the classroom next door on the second floor of Norris Hall.

When the sound of gunfire drew closer, the professor braced himself against the door, holding it shut against the gunman in the hall, the New York Daily news reports. That allowed the students to escape.
"Students started opening windows and jumping out,” his son Joe Librescu told the Jerusalem Post.
Student Alec Calhoun told the News that the last thing he saw before jumping out the window was Librescu blocking the door.
Librescu was sent to a labor camp in Russia as a child and was saved by townspeople. In 1978, his family emigrated from Romania to Israel, and in 1986 Librescu, his wife and two sons moved to Virginia.
