Frank Hyneman Knight (November 7, 1885 – April 15, 1972) was an American economist who spent most of his career at the University of Chicago, where he became one of the founders of the Chicago school.
 Nobel laureates Milton Friedman, George Stigler and James M. Buchanan were all students of Knight at Chicago.
 Ronald Coase said that Knight, without teaching him, was a major influence on his thinking.
 F.A. Hayek considered Knight to be one of the major figures in preserving and promoting classical liberal thought in the twentieth century.
The John U. Nef Committee on Social Thought is one of several PhD-granting committees at the University of Chicago.
 It was started in 1941 by historian John Ulric Nef along with economist Frank Knight, anthropologist Robert Redfield, and University President Robert Maynard Hutchins.
Milton Friedman ( ; July 31, 1912 – November 16, 2006) was an American economist who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory, and the complexity of stabilization policy.
 With George Stigler and others, Friedman was among the intellectual leaders of the second generation of Chicago price theory, a methodological movement at the University of Chicago's Department of Economics, Law School, and Graduate School of Business from the 1940s onward.
 Several students and young professors that were recruited or mentored by Friedman at Chicago went on to become leading economists; they include Gary Becker, Robert Fogel, Thomas Sowell, and Robert Lucas, Jr.
Theodore William "Ted" Schultz ( ; 30 April 1902 – 26 February 1998) was an American economist, Nobel Laureate, and chairman of the Chicago School of Economics.
 Schultz rose to national prominence after winning the 1979 Nobel Memorial Prize in Economic Sciences.
Robert Cox Merton (born July 31, 1944) is an American economist, Nobel laureate in Economics, and professor at the MIT Sloan School of Management, known for his pioneering contributions to continuous-time finance, especially the first continuous-time option pricing model, the Black–Scholes formula.
 In 1997 he received the Nobel Prize for his contributions in Economics.
The John Bates Clark Medal is awarded by the American Economic Association to "that American economist under the age of forty who is adjudged to have made a significant contribution to economic thought and knowledge".
 According to "The Chronicle of Higher Education", it "is widely regarded as one of the field’s most prestigious awards...second only to the Nobel Memorial Prize in Economic Sciences."
 The award was made biennially until 2007, but from 2009 is now awarded every year because many deserving went unawarded.
 The committee cited economists such as Edward Glaeser and John A. List in campaigning that the award should be annual.
 The award is named after the American economist John Bates Clark (1847–1938).
 Following an average wait of 22 years, approximately 30% of past Medal winners have gone on to win the Nobel, presented annually since 1969 at the Nobel Prize Award Ceremony in Stockholm.
 Moreover, 11 of the first 17 awardees (approximately 65%) went on to win the Nobel.
Leonid "Leo" Hurwicz (August 21, 1917 – June 24, 2008) was a Polish American economist and mathematician.
 He originated incentive compatibility and mechanism design, which show how desired outcomes are achieved in economics, social science and political science.
 Hurwicz shared the 2007 Nobel Memorial Prize in Economic Sciences (with Eric Maskin and Roger Myerson) for work on mechanism design.
 To date, Leonid Hurwicz is the oldest Nobel Laureate, having received the prize at the age of 90.

 Previously she was a biological researcher at the University of California, San Francisco, who studied the telomere, a structure at the end of chromosomes that protects the chromosome.
 Blackburn co-discovered telomerase, the enzyme that replenishes the telomere.
 For this work, she was awarded the 2009 Nobel Prize in Physiology or Medicine, sharing it with Carol W. Greider and Jack W. Szostak, becoming the only Tasmanian-born Nobel laureate.
 She also worked in medical ethics, and was controversially dismissed from the Bush Administration's President's Council on Bioethics.
