Elfriede Brüning (1910-2014)

       Maybe not a big name, but noteworthy: Elfriede Brüning was the last survivng member of the Weimar-era (!) 'Bund proletarisch-revolutionärer Schriftsteller' -- the 'Association of Proletarian-Revolutionary Authors' (hey, there's even an English-language Wikipedia-entry) -- an organization whose members included Anna Seghers, Egon Erwin Kisch, Erwin Piscator, Friedrich Wolf, and apparently -- after some initial hesitance -- Bertolt Brecht. Like many from the Bund she remained in East Germany after the Second World War.
       See, for example, obituaries in the Frankfurter Allgemeine Zeitung and Die Welt. And she had her own website !
