The following lists are incomplete. Nobel laureates As of October 2020, 84 Nobel laureates were affiliated with Columbia University. 43 Nobel laureates are the alumni of Columbia University. 19 of these alumni have also served on the faculty or staff of the university. There are 41 non-alumni Nobel laureates who have been in service—as faculty, research scientists, research or postdoctoral fellows—to the university. Columbia University does not count a visiting professor as one of its own. Only those Nobel laureates who have spent a year or more at the university are counted. If Nobel laureates who have spent less than a year at the university were counted, the number of Nobel laureates affiliated with Columbia would be 96, more than any other academic institution. In addition, Columbia ranks third in the number of Nobel Laureates it has graduated compared to other institutions in the world, surpassed only by the University of Cambridge and Harvard University.
