John Charles Harsanyi was a noted Hungarian-American economist, who won a Nobel Prize in Economics for his contribution to game theory. Despite being born a Catholic in Hungary, he was rounded up to be sent to a concentration camp in Austria because of his Jewish descent toward the end of the Second World War. He managed to escape before earning his PhD in philosophy from the ‘University of Budapest’ in the late 1940s. Later, he migrated to Australia as a refugee and finished his M.A. in economics from the ‘University of Sydney’. He then received a fellowship and earned his PhD in economics from the ‘University of Stanford’. After coming back to Australia, Harsanyi started working on game theory. After realizing that there was not much scope for the “un-popular subject” Down Under, he migrated to the US. He first joined the ‘Wayne State University’ in Detroit, and then moved to the ‘University of California’, Barkley, where he worked for the rest of his career. He published many seminal papers on game theory, which vastly contributed to its application in economics and earned him the coveted ‘Nobel Memorial Prize in Economic Sciences’ in 1994.
