A wonderful interview of Simone de Beauvoir by Studs Terkel, recorded May 4, 1960. This recording was re-produced as a tribute to Madame de Beauvoir by KPFK producer Lucia Chapelle in 1977, but most of the original interview remains the same. This recording is being preserved long-term through the UC Berkeley Library with grant funds provided by the National Historical Publications and Records Commission.
