Henri Theil (October 13, 1924, in Amsterdam – August 20, 2000^[1]) was a Dutch econometrician.

He graduated from the University of Amsterdam. He was the successor of Jan Tinbergen at the Erasmus University Rotterdam. Later he taught in Chicago and at the University of Florida. He is most famous for his invention of 2-stage least squares. This estimation technique greatly simplified estimation of simultaneous equation models of the economy and came into widespread use for this purpose. He is also famous for the Theil index, a measure of entropy, which belongs to the class of Kolm-Indices and is used as an inequity indicator in econometrics.^[2] He is also responsible for the Theil–Sen estimator for robust regression.
