He was able to correct a number of mistakes, fill some earlier gaps in the evidence, resolve some previously irresolvable problems, and detect some previously unknowable complications. He has published the results in the form of three articles; this lecture will summarize his main findings.\r\n \r\n Lothar von Falkenhausen is Distinguished Professor of Chinese Archaeology and Art History at UCLA, where he has taught since 1993. He is also on the faculty of the Cotsen Institute of Archaeology at UCLA, of which he served as Associate Director from 2004 to 2014, and he holds a concurrent part-time appointment as Visiting Professor (formerly Changjiang Chair, 2017-20) at Xibei University in Xi\u2019an (China). Falkenhausen was educated at Bonn University, Peking University, Kyoto University, and Harvard University, receiving his PhD in anthropology from Harvard in 1988. His research mainly concerns the archaeology of Bronze Age China, focusing on large interdisciplinary and historical issues on which archaeological materials can provide significant new information. His major books are \"Suspended Music: Chime Bells in the Culture of Bronze Age China\" (1993) and the award-winning \"Chinese Society in the Age of Confucius (1000-250 BC): The Archaeological Evidence\" (2006; also published in Japanese, Korean, and Chinese translations). A new monograph on the economic archaeology of Late Bronze Age and Early Iron Age China is in press. Falkenhausen was co-Principal Investigator of an international archaeological project on ancient salt production in the Yangzi River basin (1999-2004) and has been serving as Instructor of Record of the International Archaeological Field School at Yangguanzhai (2010-). He has served on the Scientific Council of the French School of Far Eastern Studies (2005-2011) and on the US President\u2019s Cultural Property Advisory Committee (2012-2020). He is a Full Member of the German Archaeological Institute, an Honorary Research Fellow of the Shaanxi Archaeological Academy, an Honorary Professor of Zhejiang University, a Fellow of the American Academy of Arts and Sciences, a Fellow of the American Philosophical Society, and a Corresponding Member of the Acad\u00e9mie des Inscriptions et Belles-Lettres (Institut de France). \r\n\r\nIf there is anything we can do to make this event accessible to you, please contact us at chinese.studies@umich.edu.
