Liviu Librescu

Librescu, an Israeli engineering and math lecturer, was known for his research, but his son said the Holocaust survivor 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.

After surviving the Nazi killings, Librescu escaped from Communist Romania and made his way to the United States before he was killed in Monday's massacre, which coincided with Israel's Holocaust Remembrance Day.

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 Librescu was fatally shot.

"My father blocked the doorway with his body and asked the students to flee," Librescu's son, Joe Librescu, said Tuesday in a telephone interview from his home outside of Tel Aviv. "Students started opening windows and jumping out."
