Professor Dudley Maynard Phelps, who was part of the Michigan Business School faculty from 1924-67, studied and wrote about the distinct marketing environments and challenges in markets as diverse as Latin America, Western Europe, and the former Soviet Union, including work for the U.S. State Department. He received recognition for this work from the International Marketing Institute and was president of the American Marketing Association. In the 1980s, Professor Vern Terpstra continued this work and authored the most widely used text on international marketing and other books on the cultural environment of international business, and also published highly impactful research on country-of-origin effects with his PhD student C. Min Han. Terpstra was president of the Academy of International Business in 1970 and was invited to teach at several universities.
