[1] She played in Frank Wedekind's Spring Awakening (1907), Shakespeare's Romeo and Juliet (1907), A Winter's Tale (1908), and A Midsummer Night's Dream (1910).

She moved to Vienna in 1916 and by 1924 she was playing the title role in Friedrich Schiller's Mary Stuart.

[citation needed] She spoke no English at that time, and had to take a job as a factory worker until, after intensive language study, she landed a supporting role in Alfred Hitchcock's 1946 film Notorious, in which she played Claude Rains' mother, although she was only three years older than him.

In the same year, she married Hungarian counsellor and author Géza Herczeg, and had a son, Alexander.

Her last acting work involved sporadic theatre roles and poetry readings on the radio.
