Librescu is most widely known for his actions during the Virginia Tech shooting, when he held the doors to his lecture hall closed, allowing all but one of his students enough time to escape through the windows. Shot and killed during the attack, Librescu was posthumously awarded the Order of the Star of Romania, the country's highest civilian honor. Coincidentally, Librescu's act of heroism happened on the 27th of Nisan in the Jewish lunar calendar. That date is Yom HaShoah, which is Holocaust Remembrance Day in Israel.
