WASHINGTON –
Prof Liviu Librescu, a senior researcher and lecturer at Virginia Tech, is among the 32 people who were killed during a shooting rampage at the university Monday.
His wife, Marlina, and two sons, Arieh and Joe, have already begun making arrangements for his burial in Israel.

The Virginia Tech Police Department identified the campus gunman as Cho Seung-Hui, 23, a student and native of South Korea.
An official at the South Korean Foreign Ministry said that it could not rule out that the shooter was from South Korea but said it had not received any such notification from the US Embassy.
One of Prof Librescu's students, Alec Calhoun, who was with him at the classroom when the shooting started, told AP that at about 9:05 am, he and classmates heard "a thunderous sound from the classroom next door, what sounded like an enormous hammer."
When students realized the sounds were gunshots, Calhoun said, they started flipping over desks for hiding places. Others dashed to the windows of the second-floor classroom, kicking out the screens and jumping from the ledge of the room.
Calhoun said that just before he climbed out the window, he turned to look at the professor (Librescu), who had stayed behind to block the door.

Librescu's wife drove him to work on Monday, and he was killed about an hour later. His daughter-in-law Ayala, who is married to his son, Joe, told Ynet: "I heard he blocked the door of the classroom he was teaching… he must have realized that the murderer was approaching. He saved his students and was killed by gunshots."
"He has been teaching there for 20 years, and was a senior, world-renowned lecturer. He is the professor with the highest number of publications in the history of Virginia Tech. In the past, he taught at Tel Aviv University and the Technion," she added.
Ayala said that her father-in-law was passionate about his research and a dedicated family man.
A true gentleman
Prof Librescu and his wife are both Holocaust survivors who immigrated to Israel from Romania in 1978.
Librescu was an accomplished scientist in Romania, and the Communist regime had tried to prevent him from making aliyah to Israel. He was allowed to leave the country only after the Israeli prime minister at the time Menachem Begin appealed the matter to President Nicolae Ceausescu.
Several years later, Librescu left for a sabbatical in the United States and has remained there since. His first son, Arieh, lives in Israel, while his other son, Joe, resides in the US.
"I understand from friends that my father was a hero," the son Joe told Ynet. "In fact, by blocking the door with his body he saved all the students who were in the classroom."
Joe said that his parents were very happy in the United States, where they have been living since 1984. "He and my mom led a simple life, at a pastoral place in West Virginia, between hills and mountains, and he loved the school in which he taught."
"He is scientist who did not work for money, but for the pleasure he got from his occupation," he added.
Yad Vashem, Holocaustgedenkstätte in Jerusalem
 Vorgestern, am 16. April, wurde in Israel Jom haScho'a, der Holocaustgedenktag, abgehalten.

Eine zweiminütige Sirene brachte um 10:00 Uhr Ortszeit das Leben in Israel zum Stillstand. Die Israelis bewahrten an diesem jährlichen Moment Stillschweigen, um damit der Opfer der Nationalsozialisten und ihrer Kollaborateure zu gedenken. Fußgänger blieben stehen, Bus- und Autofahrer fuhren an den Straßenrand und hielten inne.

Auf die Sirenen folgten Gottesdienste, die in der Knesset und Yad Vashem, der „Gedenkstätte der Märtyrer und Helden des Staates Israel im Holocaust“, abgehalten wurden. In der Knesset las Ministerpräsident Ehud Olmert die Namen der Mitglieder der Familie Richter vor, die mit seiner Frau Aliza verwandt sind und im Holocaust getötet wurden. Währenddessen verlas Benjamin Netanyahu, Vorsitzender der Opposition, die Namen der Verwandten seiner Frau Sara. Vize-Ministerpräsident Shimon Peres sprach über den Verlust seines Großvaters, während Sozialminister Isaac Herzog über den Cousin seines Vaters sprach, der gefangen genommen und nach Auschwitz gebracht wurde, als er versuchte, die französische Grenze zu passieren. Gedenkgottesdienste wurden zusätzlich über den Tag verteilt an allen Schulen und Institutionen abgehalten.
