Leonid "Leo" Hurwicz was an economist and mathematician, born in Moscow. He originated incentive compatibility and mechanism design, which show how desired outcomes are achieved in economics, social science and political science. Interactions of individuals and institutions, markets and trade are analyzed and understood today using the models Hurwicz developed. To date, Leonid Hurwicz is the oldest Nobel Laureate, having received the prize at the age of 90. Hurwicz was Regents' Professor of Economics at the University of Minnesota. He was among the first economists to recognize the value of game theory and was a pioneer in its application. Hurwicz shared the 2007 Nobel Memorial Prize in Economic Sciences with Eric Maskin and Roger Myerson for their work on mechanism design.
