Claude Ponsard (1927–1990) was a French economist who worked in spatial economics and in the application of fuzzy set theory to economics. Bo Yuan and George J. Klir noted that Ponsard was a "pioneer who initiated the reformulation of economic theory by taking advantage of fuzzy set theory" in their book, Fuzzy sets and fuzzy logic theory and applications (1995).^[1]
