In 1939, he fled Poland to escape the Nazi invasion, but was imprisoned by the Soviet Russians and worked at a labor camp in Siberia. Zarnowitz earned his Ph.D. in economics (summa cum laude) at the
University of Heidelberg in Germany in 1951. He came to the United States in 1952. In 1959 he moved to Chicago and became a professor at the University of Chicago. He was a Fellow of the National Association of Business Economists, Fellow of the American Statistical Association, Honorary Fellow of the International Institute of Forecasters, and Honorary Member of the Center for International Research on Economic Tendency Surveys (CIRET). In 2001, he received the William F. Butler Memorial Award from the New York Association for Business Economists. His numerous papers and books include An Appraisal of Short-Term Economic Forecasts (1967), The Business Cycle Today (1972), Orders, Production, and Investment (1973), and Business Cycles: Theory, History, Indicators, and Forecasting (1992). His most recent papers are "Has the Business Cycle Been Abolished?" (1998), "Theory and History Behind Business Cycles" (1999), and "The Old and the New in U.S. Economic Expansion" (2000). He was notable as a researcher on the performance of economic forecasting, and he concluded that economic forecasters have little success in predicting business cycle turning points. In 2008, Zarnowitz published a book about his experiences with Nazis and Russians, "Fleeing the Nazis, Surviving the Gulag, and Arriving in the Free World: My Life and Times," which received wide praise. The historical pattern in which deep recessions are usually followed by steep recoveries is known by economists as "the Zarnowitz rule". ==Publications==
