Jan T. Gross studies modern Europe, focusing on comparative politics, totalitarian and authoritarian regimes, Soviet and Eastern European politics, and the Holocaust. After growing up in Poland and attending Warsaw University, he immigrated to the United States in 1969 and earned a Ph.D. in sociology from Yale University (1975). His first book, Polish Society under German Occupation, appeared in 1979. Revolution from Abroad (1988) analyzes how the Soviet regime was imposed in Poland and the Baltic states between 1939 and 1941. Neighbors (2001), which was a finalist for the National Book Award, reconstructs the events that took place in July 1941 in the small Polish town of Jedwabne, where virtually every one of the town’s 1,600 Jewish residents was killed in a single day. He is also the coeditor of The Politics of Retribution in Europe: World War II and Its Aftermath (2000), and the coeditor with Irena Grudzinska-Gross of War Through Children’s Eyes (1981), which uses school compositions and other documents written by children to study how children experience war and deportation. He joined the Princeton History Department in 2003 after teaching at New York University, Emory, Yale, and universities in Paris, Vienna, and Krakow. He is Professor of History, emeritus, at Princeton University.
