<p>Although a lot more UChicago faculty have won the Nobel prize, more alumni from MIT and Harvard have won the Nobel prize [source <a href=“http://www.shanghairanking.com/SubjectEcoBus2011.html][/url”>http://www.shanghairanking.com/SubjectEcoBus2011.html][/url</a>]. The alumni data combines bachelors and graduate alumni so I’m not certain which school has had more undergraduate alumni win the prize. In any case, this is probably not particularly relevant to the OP.</p>
