Stefan Bradley, history and African American studies professor at Saint Louis University, recalls the efforts by African-American students and the residents of Harlem to stop Columbia University from building a private gymnasium and expanding the University’s footprint in 1968-69. Mr. Bradley focuses on the residents of Harlem’s protest and the radicalization of portions of Columbia’s student body, including the SDS (Students for a Democratic Society) led by Mark Rudd and the SAS (Students' Afro American Society). Stefan Bradley discusses his book at the Brecht Forum in New York City.
