the University of Chicago in 1931–1932 studying with Frank Knight and Jacob Viner. Coase's colleagues would later admit that they did not remember this first visit. Between 1932 and 1934, Coase was an assistant lecturer at the Dundee School of Economics and Commerce, which later became part of the University of Dundee. Subsequently, Coase was an assistant lecturer in commerce at the University of Liverpool between 1934 and 1935 before returning to London School of Economics as a member of staff until 1951 in which year he was awarded an earned doctorate in economics from the University of London. He then started to work at the University at Buffalo and retained his British citizenship after moving to the United States in the 1950s. In 1958, he moved to the University of Virginia. Coase settled at the University of Chicago in 1964 and became the co-editor of the Journal of Law and Economics with Aaron Director. He was also for a time a trustee of the Philadelphia Society. He received the Nobel Prize in Economics in 1991. Nearing his 100th birthday, Coase was working on a book concerning the rise of the economies of China and Vietnam. In an interview, Coase explained the mission of the Coase China Society and his vision of economics and the part to be played by Chinese economists. This became "How China Became Capitalist" (2012) co-authored with Ning Wang. Coase was honoured and received an honorary doctorate from the university at Buffalo Department of Economics in May 2012. Coase married Marion Ruth Hartung of Chicago, Illinois in Willesden, England, 7 August 1937. Although they were unable to have children, they were married 75 years until her death in 2012, making him one of the longest-married Nobel Prize laureates. Coase himself died in Chicago on 2 September 2013, at the age of 102. His wife had died on 17 October 2012. He was praised across the political spectrum, with Slate calling him "one of the most distinguished economists in the world" and Forbes calling him "the greatest of the many great University of Chicago economists". The Washington Post called his work over eight decades "impossible to summarize" while recommending five of his papers to read. An important point is that his only student is Steven N. S. Cheung, and both works should be read together. Coase said or wrote once (ref and quote: TBA) that Steven Cheung
