Dr. Raup's work in international affairs made him one of the leading scholars in world agriculture. After receiving his undergraduate degree in economics from the University of Kansas and an M.S. and Ph.D. from the University of Wisconsin, he spent a year as a research fellow at the Brookings Institution before entering the military. He spent four years in the Office of Military Government for Germany in Berlin, the first of many international experiences in his career. He returned to the United States in 1949 to join the faculty of the University of Wisconsin, leaving in 1953 for the University of Minnesota. While there, he became one of the nation's few scholars on the agriculture of Eastern Europe and the former Soviet Union. During a 20 year period, he visited the same locations in the former Soviet Union and combined his observations into a book, The Changing Structure of Europe: Economic, Social, and Political Trends, coauthored with four of his University of Minnesota colleagues.
Dr. Raup served on the Board of Directors of the AAEA from 1975 to 1978. He was named a fellow of the AAEA in 1981.
