Liviu Librescu (August 18, 1930 – April 16, 2007; Hebrew: ליביו ליברסקו‎) was a Romanian born and educated Israeli-American scientist and academic professor whose major research fields were aeroelasticity and aerodynamics. While a prominent academic, he is most widely known for his act of heroism during the Virginia Tech massacre, in which he held off the gunman, giving all but one of his students enough time to escape through the windows.[3] Librescu was shot and killed during the attack. Librescu was posthumously awarded the Order of the Star of Romania, Romania's highest civilian honor. At the time of his death, he was Professor of Engineering Science and Mechanics at Virginia Tech.[4]

[edit] Life and career

Liviu Librescu was born in 1930 to a Jewish family in the city of Ploieşti, Romania. After Romania allied with Nazi Germany in World War II, his father, Isidore Librescu, was deported to a labor camp in Transnistria, and later his family, along with thousands of other Jews, was deported to a ghetto in the Romanian city of Focşani.[5][6] As a boy, Librescu was interned in a labor camp in Transnistria. He may also have spent time in a Soviet labor camp.[6] His wife, Marlena, who is also a Holocaust survivor, told Israeli Channel 10 TV the day after his death, "We were in Romania during the Second World War, and we were Jews there among the Germans, and among the anti-Semitic Romanians."[5] Dorothea Weisbuch, a cousin of Librescu living in Romania, said in an interview to Romanian newspaper Cotidianul: "He was an extraordinarily gifted person and very altruist. When he was little, he was very curious and knew everything, so that I thought he would become very conceited, but it did not happen so; he was of a rare modesty."[7]

After surviving the Holocaust, Librescu was repatriated to Communist Romania.[5] He studied aerospace engineering at the Polytechnic University of Bucharest, graduating in 1952 and continuing with a Master's degree at the same university. He was awarded a Ph.D. in fluid mechanics in 1969 at the Academia de Ştiinţe din România.[8] From 1953 to 1975, he worked as a researcher at the Bucharest Institute of Applied Mechanics, and later at the Institute of Fluid Mechanics and the Institute of Fluid Mechanics and Aerospace Constructions of the Academy of Science of Romania.

His career stalled in the 1970s because he refused to swear allegiance to the Romanian Communist Party and was forced out of academia for his sympathies towards Israel.[5] When Librescu requested permission to emigrate to Israel, the Academy of Science of Romania fired him.[9][5] In 1976, a smuggled research manuscript that he had published in the Netherlands drew him international attention in the growing field of material dynamics.[10]

After years of government refusal, Israeli Prime Minister Menachem Begin personally intervened to get the Librescu family an emigration permit by directly asking Romanian President Nicolae Ceauşescu to let them go.[11][5] They moved to Israel in 1978.

From 1979 to 1986, Librescu was Professor of Aeronautical and Mechanical Engineering at Tel Aviv University and taught at the Technion in Haifa.[11] In 1985, he left on sabbatical for the United States, where he served as Professor at Virginia Tech in its Department of Engineering Science and Mechanics from September 1, 1985, until his death.[11][12] He served as a member on the editorial board of seven scientific journals and was invited as a guest editor of special issues of five other journals.[13] Most recently, he was co-chair of the International Organizing Committee of the 7th International Congress on Thermal Stress, Taipei, Taiwan, June 4–7, 2007, for which he had been scheduled to give the keynote lecture.[4][13] According to his wife, no other Virginia Tech professor has ever published more articles than Librescu.[11]

At age 76,[11] Librescu was among the 32 people who were murdered in the Virginia Tech massacre. On April 16, 2007, Seung-Hui Cho entered Norris Hall Engineering Building and opened fire on classrooms. Librescu, who taught a solid mechanics class in Room 204 in the Norris Hall during April 2007,[14] held the door of his classroom shut while Cho was attempting to enter it. Although he was shot through the door, Librescu managed to prevent the gunman from entering the classroom until most of his students had escaped through the windows.[15][16][17] He was struck by five bullets,[18] with a shot to the head ending his life.[19] Of the 23 registered students in his class, one, Minal Panchal, died.[20]

A number of Librescu's students have called him a hero because of his actions. Caroline Merrey, a senior, said she and about 20 other students scrambled through the windows as Librescu shouted for them to hurry.[18] Merrey said, "I don’t think I would be here if it wasn't for [Librescu]."[21] Librescu's son Joe said he had received e-mails from several students who said he had saved their lives and regarded him as a hero,[11] while many newspapers also reported him as the hero of the massacre.

Following the murder of Librescu, at the request of his family and with the assistance of Gov. Tim Kaine, his body was released on April 17[22] and he received a funeral service at a Jewish Orthodox funeral home in Borough Park, Brooklyn, New York City, New York[18]. On April 20, he was interred in Israel.[23][24][25] In his native Romania, his picture was placed on a table at the Polytechnic University of Bucharest, and a candle was lit. People laid flowers nearby.[5]

The murder took place on Holocaust Remembrance Day (Yom HaShoah). On April 18, 2007, US President George Bush honored Librescu at a memorial service held at the US Holocaust Museum, attended by a crowd that included many Holocaust survivors:

That day we saw horror, but we also saw quiet acts of courage. We saw this courage in a teacher named Liviu Librescu. With the gunman set to enter his class, this brave professor blocked the door with his body while his students fled to safety. On the Day of Remembrance, this Holocaust survivor gave his own life so that others may live. And this morning we honor his memory and we take strength from his example.[26]

[edit] Honors and awards

Librescu received many academic honors during his work in the Engineering Science and Mechanics Department at Virginia Tech, serving as chair or invited as a keynote speaker of several International Congresses on Thermal Stresses and receiving several honorary degrees. He was elected member of the Academy of Sciences of the Shipbuilding of Ukraine (2000) and Foreign Fellow of the Academy of Engineering of Armenia (1999). He was a recipient of Doctor Honoris Causa of the Polytechnic Institute of Bucharest (2000), of the 1999 Dean's Award for Excellence in Research, College of Engineering at Virginia Tech, and a laureate of the Traian Vuia Prize of the Romanian Academy (1972). He was a member of the Board of Experts of the Italian Ministry of Education, University and Scientific Research. He was awarded the Engineering Science and Mechanics Frank J. Maher Award for Excellence in Engineering Education (2005) and an ASME diploma (2005) expressing "deep appreciation for the valuable services in advancing the engineering profession".[13]

Posthumously, Professor Librescu was commended by Traian Băsescu, the President of Romania, with the Order of the Star of Romania with the rank of Grand Cross, "as a sign of high appreciation and gratitude for the entire scientific and academic activity, as well as for the heroism shown in the course of the tragic events which took place on April 16th, 2007, [...] through which he saved the lives of his students, sacrificing his own life."[27] The Chabad Hasidic Movement named its Jewish Student Center at Virginia Tech after him [28].
