Die Musik. But it was already shown to be a hoax by Newman (1911)—a last-ditch effort to salvage the discredited Guicciardi hypothesis. The date of the "Immortal Beloved" letter—6/7 July 1812—has meanwhile been firmly established, not only by watermarks and references, but also by a later letter by Beethoven to Rahel Varnhagen, which suggests he must have met his "Immortal Beloved" on 3 July 1812: "I am sorry, dear V., that I could not spend the last evening in Prague with you, and I myself found it impolite, but a circumstance I could not foresee prevented me." La Mara (1920), after discovering more letters and notes in the Brunsvik estates, was now convinced "that ... Josephine widowed Countess Deym was Beethoven's 'Immortal Beloved'". Czeke (1938), for the first time, published Therese's diary notes ending in 1813; some were known already to Rolland (1928). and concluded that Beethoven was in love with Josephine, but nonetheless he tended towards Therese as the "Immortal Beloved". Kaznelson (1954) evaluated more of the documents in the Brunsvik estates, and even though he thought that Rahel Varnhagen was behind the "Distant Beloved" he concluded that the "Immortal Beloved" must have been Josephine mainly because her daughter Minona was born exactly nine months after the encounter with Beethoven and her husband Baron Stackelberg was away. Kaznelson arrived at his conclusion even though H C Bodmer in Zürich, owner of the "13 Letters" after World War II (see following), would not allow him access to them. Editha and Richard Sterba (1954), using psychoanalysis, argued for Beethoven's nephew Karl as the "Immortal Beloved". Steichen (1959) identified Marie Erdödy to have been a lifelong beloved of Beethoven, and thus she could also be the "Immortal Beloved". Marek (1969) argued the case for Dorothea Ertmann. The discovery of Josephine Brunsvik (1957 to 1999) Schmidt-Görg (1957) published 13 heretofore unknown love letters by Beethoven to Josephine Brunsvik (and a draft letter by him that survived as a copy by Josephine), that could be dated to the period from 1804 to 1809/10 when she was a widow after the early death of her first husband Count Deym. Schmidt-Görg dismissed Kaznelson's discoveries as "sensationalist". Goldschmidt (1980) explains why the German Beethoven scholarship was so reluctant to accept Kaznelson's theory (already published before these "13 letters"): "The fact that, as a result of this meeting, they had to take a natural daughter into account, appeared
