Librescu was an Israeli engineering and math lecturer known for his research, but his son said he will be remembered as a hero for protecting students as the gunman tried to enter his classroom.
Librescu taught at Virginia Tech for 20 years and had an international reputation for his work in aeronautical engineering. "His research has enabled better aircraft, superior composite materials, and more robust aerospace structures," said Ishwar K. Puri, the head of the engineering science and mechanics department.
Librescu's son, Joe, said his father's students sent e-mails detailing how the professor saved their lives by blocking the doorway of his classroom from the approaching gunman before he was fatally shot. "My father blocked the doorway with his body and asked the students to flee," Joe Librescu said Tuesday in a telephone interview from his home outside of Tel Aviv. "Students started opening windows and jumping out."
