The origins, history, and final demise of discriminatory admissions policies at Harvard, Princeton and Yale are examined. It is reported that by the early 1920's the Big Three racial and religious quotas were fully operative in response to the influx of Jews, Catholics, and other new groups that threatened the hegemony of the old-stock Americans who traditionally composed the student body. The discrimination suffered by the Jewish and Catholic students who were admitted to these universities is revealed. Change in the admissions policies came after World War II with the increase in democratization. It is shown how admissions on the basis of merit helped these colleges preserve their traditions of academic excellence. Chapters discuss the changing campus, various policies and philosophies held by college presidents, admissions policies, student experiences at these colleges, and events leading to change and growth. Tables offer statistical information such as: percentage of Jewish students at 30 colleges and universities, 1918-1919; Jewish and Gentile students under discipline, 1912-1913 to 1921-1922; scholarships awarded to Jewish students at Yale, 1911-1925; and religious preferences of Yale undergraduates and graduate students, l947-1954. Notes are provided on each chapter offering clarification and references and an index of terms. (LC)
