In my view—and that of most contemporary economists, I believe—Schumpeter's most original and most lastingly significant book was Theory of Economic Development, which appeared in 1911 (and was translated into English in 1934). It was at the University of Czernowitz, not far from the beginning of his career as an economist, that he worked out his conception of the entrepreneur, the maker of new combinations, as the driving force and characteristic figure of the fits-and-starts evolution of the capitalist economy. He was explicit that, while technological innovation was in the long run the most important function of the entrepreneur, organizational innovation in governance, finance, and management was comparable in significance.
