In 1942, a priceless Chinese treasure was looted: the only surviving Warring States period silk manuscripts. These were illegally taken to America by U.S. citizen John Hadley Cox, where they have remained ever since. Many in the international scholarly community, including Professor Donald Harper of the University of Chicago and Professor Lothar von Falkenhausen of the University of California, Los Angeles, have called attention to this act of cultural theft and urged that the silk manuscripts be returned to China.
