Vartan Gregorian, the ebullient Armenian immigrant who climbed to pinnacles of academic and philanthropic achievement but took a detour in the 1980s to restore a fading New York Public Library to its place at the heart of American intellectual life, died on Thursday April 15 2021 in Manhattan. He was 87. His death was confirmed by his son Dareh Gregorian. Vartan Gregorian was the twelfth president of Carnegie Corporation of New York, a grant-making institution founded by Andrew Carnegie in 1911. Prior to his current position, which he assumed in June 1997, Gregorian served for nine years as the sixteenth president of Brown University. He was born in Tabriz, Iran, of Armenian parents, receiving his elementary education in Iran and his secondary education in Lebanon. In 1956 he entered Stanford University, where he majored in history and the humanities, graduating with honors in 1958. He was awarded a Ph.D. in history and humanities from Stanford in 1964. Gregorian has taught European and Middle Eastern history at San Francisco State College, the University of California at Los Angeles, and the University of Texas at Austin. In 1972 he joined the University of Pennsylvania faculty and was appointed Tarzian Professor of History and professor of South Asian history. He was founding dean of the Faculty of Arts and Sciences at the University of Pennsylvania in 1974 and four years later became its twenty-third provost until 1981. For eight years (1981-1989), Gregorian served as a president of the New York Public Library, an institution with a network of four research libraries and eighty-three circulating libraries. In 1989 he was appointed president of Brown University. He serves on the boards of the Institute for Advanced Study, Brandeis University, Human Rights Watch, the World Trade Center Memorial Foundation, and the Museum of Modern Art.
