As an alum of Stony Brook, I’m grateful for all Jim Simons did for the university. Aside from having been the chairman of the math department, he’s the reason we have the Simons Center for Geometry and Physics, as well as the “Renaissance” School of Medicine. Not to mention his recent gift of $500 million—the largest unrestricted donation to a public university in American history. I’m sure there’s much, much more that he’s done that I’m not even aware of.
