Orris Clemens Herfindahl (June 15, 1918 in Parshall, North Dakota - December 16, 1972 while traveling in Nepal) was an economist who studied natural resources. However, he is mainly known as the inventor of a concentration index (the Herfindahl index) which he proposed in his 1950 doctoral dissertation on the steel industry while at Columbia University.
