The Comtesse de Chambrun’s son, René, marries Pierre Laval’s daughter in 1935. Laval is a prominent figure under Pétain’s government under occupied France. Chambrun’s connection with Laval helps the American Library remain open during the Nazi turmoil. However, this connection also implies collaboration with the Germans. René de Chambrun is blacklisted as is clear in a Life Magazine of August 1942.
