Peter Hayes is Professor Emeritus of History and German and Theodore Zev Weiss Holocaust Educational Foundation Professor Emeritus of Holocaust Studies at Northwestern University and a former chair of the Academic Committee of the United States Holocaust Memorial Museum. Among his thirteen books are The Oxford Handbook of Holocaust Studies (co-edited with John K. Roth), How Was It Possible? A Holocaust Reader, and Why? Explaining the Holocaust, which also has appeared in German and Spanish translations and shortly will be in Chinese, Polish, and Slovak, as well.

Only a day after the University of Southern California announced that it would conduct a three-day test to move all classes online, which soon turned into a permanent arrangement until the end of Spring semester, my colleague and I gave our last in-person introduction to the USC Shoah Foundation Visual History Archive to a USC class. Perhaps serendipitously, one of the topics discussed in this class was physical health.
