Regents’ Professor Emeritus of Economics at the University of Minnesota and recipient of the 2007 Nobel Memorial Prize in Economic Science for his work in mechanism design. The Leonid Hurwicz Papers span the years 1930-2008, covering his entire career as an economist in the United States, from his early work at MIT, the University of Chicago and the Cowles Commission until his death as an Emeritus Professor at the University of Minnesota. The collection is arranged in the following series: Correspondence, Electronic Files, Personal Files, Printed Material, Professional Services Series, Research and Writings, and Teaching Material. Though there are correspondence, legal, financial, and other papers documenting his migration to the United States, there have been no items discovered that document his training as an economist at the University of Warsaw or at the London School of Economics. The majority of the collection focuses on Hurwicz's work after 1970, most notably his collaborations with Stanley Reiter, Kenneth Arrow, Don Saari, Thomas Marschak and Marcel Richter.
