 During the mid- and late 1940s, the University was the target of critical editorials in the local African American press, letter-writing campaigns by churches and the local Urban League, and legal briefs by the NAACP intended to strip its tax-exempt status.In spring 1949, a Washington University student group, the Student Committee for the Admission of Negroes (SCAN), began campaigning for full racial integration.The administration continued to hold that full desegregation "would place the University outside of the community," as Vice-Chancellor Leslie Buchan claimed in 1951, and could spark "incidents on campus."
