No no though, let's ignore the truth.
"Although never officially legislated, between 1918 and the 1950s a number of private universities and medical schools introduced numerus clausus policies limiting admissions of students based on their religion or race to certain percentages within the college population. One of the groups affected by these policies was Jewish applicants whose admission to some New England and New York City area liberal arts universities fell significantly between the late 1910s and the mid-1930s. For instance, the admission to Harvard University during that period fell from 27.6% to 17.1% and in Columbia University from 32.7% to 14.6%. Corresponding quotas were introduced in the medical and dental schools resulting during the 1930s in the decline of Jewish students: e.g. in Cornell University School of Medicine from 40% in 1918-22 to 3.57% in 1940-41, in Boston University Medical School from 48.4% in 1929-30 to 12.5% in 1934-35. During this period, a notable exception among U. S. medical schools was the medical school of Middlesex University, which had no quotas and many Jewish faculty members and students; school officials believed that antisemitism played a role in the school's failure to secure AMA accreditation."
"In addition to Jewish applicants, Catholics, African-Americans, Eastern/Southern Europeans, and women were also targeted by admission restrictions. African-Americans, in some instances, were outright excluded (numerus null) from admission e.g., at Columbia University. The most common method, employed by 90% of American universities and colleges at the time to identify the "desirable" (native-born, white, Protestant) applicants were the application form questions about their religious preference, race, and nationality."
