Noelle-Neumann completed her visiting position in Chicago in mid-December 1991 and returned to Germany. When some University of Chicago students learned that she was to return there on March 13, 1992, they called a rally to protest against her return. Reached by telephone at her office in Allensbach am Bodensee, Germany, on March 10, Noelle-Neumann told a reporter she was unaware of the proposed rally but intended on coming to the university as planned. That day, her hosts at the National Opinion Research Center announced that she had cancelled her appearance "in light of serious threats".
