A 1922 article from THE LITERARY DIGEST in which Harvard President Abbott Lawrence Lowell (1856 – 1943) attempted to avoid the obvious topic involving his wish to admit Jews by quota and keep their numbers limited to a particularly low proportion.
Lowell worried that living on campus with a significant number of Jews would poison the social experience of the members of the Protestant elite and cause them to send their sons elsewhere, just as the New York City social set turned away from Columbia in that century's first decade. In 1923, President Lowell came up with a politically palatable solution: he limited the size of the incoming class to one thousand, which meant incorporating an evaluation of each candidate's nonacademic qualities into the admissions decision. How "manly" was the candidate, for instance? How congenial and "clubbable"? What promise, what potential for future leadership?
Today, Harvard is far more comfortable discriminating against Asians.
