In this chapter, David Plane discusses the career of Edward Ullman, an American geographer who helped shape the early development of regional science. Ullman was among the pioneers of a more analytical and policy-relevant approach to the discipline of geography, and his three ‘bases of spatial interaction’ are now among its core concepts. An active participant in the formative years of regional science professional organizations, he made major contributions in three areas that remain at the heart of regional science: transportation networks and flows, cities and settlement systems, and the economic structure and development of regions. Ullman’s work blended theory, empirical data, mapping, and traditional geographic description of regions. The bases he laid down for works in regional science live on to the present day. |
