[Jon C. Hopwood on Herbert J. Biberman]: Biberman was arraigned before HUAC in 1947, where he was one of 19 unfriendly witnesses who refused to answer the Committee's inquiry into their political affiliations. The 19 eventually became the Hollywood Ten, as others of the 19 dropped away, including such luminaries as Bertolt Brecht, who left the U.S. for East Germany.
