The Man Who Saved Students, By Sacrificing His Life

Romanian-born Israeli and American scientist, engineer, professor, teacher, and a Holocaust survivor, Liviu Librescu, held the door of his classroom during the Virginia Tech shootings sacrificing his life while the gunman continuously shot through the door saving 22 of his 23 students.

At age 76,Librescu was among the 32 people who were murdered in the Virginia Tech shootings. On April 16, 2007, Seung-Hui Cho entered the Norris Hall Engineering Building and opened fire on classrooms. Librescu, who taught a solid mechanics class in Room 204 in the Norris Hall during April 2007, held the door of his classroom shut while the gunman attempted to enter it. Although he was shot through the door, Librescu managed to prevent the gunman from entering the classroom until most of his students had escaped through the windows.He was struck by five bullets, with a shot to the head proving to be fatal.
