RIP Ken Arrow (1921–2017)

Ken Arrow, who was the youngest recipient of the Nobel Memorial Prize in Economics, has died

Like many Nobel-memorial laureates in economics, Arrow has an undergraduate degree in mathematics (in his case, as part of a double major with social science). He also earned a Masters degree in mathematics. Arrow has an entry in the Mathematics Genealogy Project.

Some of my students have heard me mention "impossibility theorems" in voting and social choices. If you're going to name one pioneer in that area, that person is Ken Arrow.
