JERUSALEM — An Israeli lecturer who died in the massacre at a U.S. university saved the lives of several students by blocking the doorway of his classroom from the approaching gunman before he was fatally shot, his son said Tuesday.
Students of Liviu Librescu, 76, a holocaust survivor who was an engineering science and mathematics lecturer at Virginia Tech for 20 years, sent e-mails to his wife, Marlena, telling of how he blocked the gunman's way and saved their lives, said the son, Joe.
"My father blocked the doorway with his body and asked the students to flee," Joe Librescu said in a telephone interview from his home outside of Tel Aviv. "Students started opening windows and jumping out."

Liviu Librescu, was respected in his field, his son said.
