Jan Tinbergen

Jan Tinbergen (; ; 12 April 19039 June 1994) was a Dutch economist who was awarded the first Nobel Memorial Prize in Economic Sciences in 1969, which he shared with Ragnar Frisch for having developed and applied dynamic models for the analysis of economic processes. He is widely considered to be one of the most influential economists of the 20th century and one of the founding fathers of econometrics. His important contributions to econometrics include the development of the first macroeconometric models, the solution of the identification problem, and the understanding of dynamic models. Tinbergen was a founding trustee of Economists for Peace and Security. In 1945, he founded the Bureau for Economic Policy Analysis (CPB) and was the agency's first director. Biography Tinbergen was the eldest of five children of Dirk Cornelis Tinbergen and Jeannette van Eek. His brother Nikolaas "Niko" Tinbergen would also win a Nobel Prize (for physiology, during 1973) for his work in ethology, while his youngest brother Luuk would become a famous ornithologist. Jan and Nikolaas Tinbergen are the only siblings to have both won Nobel Prizes. Between 1921 and 1925, Tinbergen studied mathematics and physics at the University of Leiden under Paul Ehrenfest. During those years at Leiden, he had numerous discussions with Ehrenfest, Kamerlingh Onnes, Hendrik Lorentz, Pieter Zeeman, and Albert Einstein.
