President Lowell of Harvard tried to impose a 12% quota on Jewish admits in the early 20th century, and also attempted to exclude African American students from residing in the freshman dorms. You can find similar behavior at other universities until well after WWII ended. For example, Georgetown's first black student enrolled in 1950.
OK, so some colleges in the 20s and 30s discriminated against Jews and others (vast majority?) didn't. Your link goes on about Feynman and Salk going to NYU and MIT instead of their first choices. These men both easily found their way to the elite.
