She translated over seventy books into German from English, Russian and French, including work by Upton Sinclair, John Galsworthy, Jerome K. Jerome, Harold Nicolson, Max Eastman and Edna Ferber.

A committed socialist from a Viennese aristocratic Catholic family, she was sometimes called the Red Countess.
