In this photo released by the Librescu family in Israel, Tuesday, April 17, 2007, Romanian-born lecturer Liviu Librescu is seen in an undated photo. The Israeli lecturer killed in the Virginia Tech massacre was a Holocaust survivor who later escaped from Communist Romania. Relatives said Librescu, an internationally respected aeronautics engineer and a lecturer at Virginia Tech for 20 years, saved the lives of several students by blocking the gunman before he was gunned down in Monday's shooting, which coincided with Israel's Holocaust remembrance day.
