Boarding houses had to be approved by the University of Minnesota for students to reside there. Householders who ran boarding houses were allowed to submit to the University of Minnesota preference cards indicating types of students who they would not accept. Jews and “Negroes” were the first two categories. By the 1940s, they also included foreigners and Asians. This document summarizes the boarding house preference cards by neighborhood and groups excluded. The University Senate collected this information and finally called on the University to reject the practice in 1954, in part due to the activism of the Student NAACP on campus.
