The latest to pass away is Kenneth Arrow, who by any and all accounts was a genius. **A Fine Theorem** tells us what we already know, that “* Arrow is so influential, in some many areas of economics, that it is simply impossible to discuss his contributions in a single post*.”

These contributions, of course, include work on social choice theory (Arrow’s Impossibility Theorem), general equilibrium theory, and innovation, and off the top of my head I can point to work on health care, organizational theory, quasi-option values, and a bunch of other stuff. Truly remarkable. Here is the *New York Times* obituary.

Meanwhile, the profession has also recently lost Thomas Schelling (2016), Douglass North (2015), John Nash (2015), Gary Becker (2014), Ronald Coase (2013), and Elinor Ostrom (2012). You could learn a lot in a little while just reading the obits on these Nobel Prize winners.
