A 77-year-old Virginia Tech professor who barred the door to his classroom against the gunman wreaking havoc down the hall sacrificed his life to save his students. Professor Liviu Librescu was teaching a class on solid mechanics when he heard gunshots. He held the door closed as students escaped through the window, and was shot through the door.
The heroic professor taught aerospace and ocean engineering, and once did research for NASA. His wife and two sons plan to bury him in Israel, the Daily News reports. "He realized he had to save the students," said his daughter-in-law Ayala Schmulevich. "That was the kind of man he was."
