In the 1950s and 1960s, most students were Americans, Italians, and Greeks. In the 1970s came the Arabs and Iranians. In the 1980s came Japanese and Koreans, and in the 1990s came the Russians. During the 1990s, came the children of Russian oligarchs, who made up a third of the student body. They "terrorized" other students, which resulted in the withdrawal of at least one non-Russian student.
