Later she attended school in Berlin and in Weimar, where she began to attend theatre.
Born in Rostock, Hoppe became a leading lady of stage and films in Germany. In 1935 she was hired by the controversial German actor and Director of the Prussian State Theatre under the Third Reich, Gustav Gründgens. Speaking years after the marriage had ended Hoppe stated, "He was my love, but never my great love, that was work." One of the characters in the film Mephisto was reportedly based on her.
Hoppe made no secret of her contacts with the Nazi elite in the 1930s/40s, including being invited to dinner by Hitler.
Her role in Der Schimmelreiter (The Rider of the White Horse, 1934) made her famous almost overnight, while her "Aryan" face made her a darling of the Nazi elite. Later Hoppe would label this period of her life as "the black page in my golden book".
During her time acting at the home of the Prussian State Theatre, the Schauspielhaus, Hoppe developed her analytical approach to acting, which she stated consisted in her "taking apart every sentence" and giving the use of language a brilliance. This method was to be associated with Hoppe throughout her working life.
She became a favourite of the young and iconoclastic directors Claus Peymann, Robert Wilson and Frank Castorf.
Hoppe died in Siegsdorf, Bavaria, in 2002 from natural causes, aged 93. "German theater has lost its queen", said Claus Peymann of the Berliner Ensemble, whose theatre featured Hoppe"s last performance, in Bertolt Brecht"s Resistible Rise of Arturo Ui, in December 1997. In one of her last interviews Hoppe stated, "I have a go at happiness every day.
That takes discipline, a virtue every halfway decent actor should have.".
Hoppe first performed at 17 as a member of Berlin"s Deutsches Theater under director Max Reinhardt.
