Georgetown University, a Catholic institution long known for scholarship on the Arab world, is intensifying its study of Jewish civilization with aid from a series of significant donations. The latest, to be announced Wednesday, is a $10 million gift for research on the Holocaust. A 13-year-old Jewish studies program in the Jesuit university’s prestigious School of Foreign Service will be formally renamed the Center for Jewish Civilization next week. The shift in nomenclature is not a small matter in academia: It signifies money, depth and commitment. The center will have a $20 million endowment, officials said, counting the new $10 million gift from Miami philanthropists Norman and Irma Braman. Its mission is to explore foreign policy pertaining to Israel; the Holocaust and genocide issues; Jewish-Catholic relations; and Jewish literature, culture and religious expression.
