so venturesome to the professional world that the resistance to the Josephine hypothesis stiffened noticeably." Schmidt-Görg (1957, p. 31) believed that with the last letter (which he still thought to have been written in 1807—not 1809) and with Josephine's marriage to Baron Stackelberg (in 1810) the love relationship was terminated. Ley (1957, p. 78) saw it differently: "Only on the negative side has one been able to arrive at certain conclusions: neither Giulietta Guicciardi, nor Amalie Sebald, nor Bettina Brentano can be considered any longer, and not even Therese Brunsvik, who for a long time was seriously regarded as the recipient of the famous love letter. But curiously enough, it is precisely the same documents which shed a definitive light, in the negative sense, on Therese which bear witness to Beethoven's passionate love for her sister Josephine." Riezler (1962, p. 46), still very much a "standard" German biography of Beethoven, followed Kaznelson regarding Josephine being his "only love", likewise Dahlhaus (1991, p. 247) who concluded that "internal evidence" points to Josephine. The French authors Jean and Brigitte Massin (1955) identified Josephine as the "Immortal Beloved", mainly based on comparisons of the "Letter to the Immortal Beloved" with the earlier 14 (15) love letters: "The letter to the 'Immortal Beloved'... not only uses similar wording, but also emphasizes his long-time faithfulness to his one and only Beloved." In addition, with regard to traces in Beethoven's compositions, the "Massins argue that... the presence of Josephine in Beethoven's life left traces in his music... From the standpoint of music theory, the connections make eminent sense." After Massin & Massin (1955) and Goldschmidt (1980), Tellenbach (1983, 1987, 1988, 1999) argued extensively the case for Josephine, based on many newly discovered documents, like Therese's later diary notes, e.g., on the discovery of the "Three letters by Beethoven… they must have been to Josephine whom he loved passionately." "Beethoven! It is like a dream, that he was the friend, the confidant of our house—a beautiful mind! Why did not my sister Josephine, as widow Deym, take him as her husband? Josephine's soul-mate! They were born for each other. She would have been happier with him than with Stackelberg. Maternal affection made her forgo her own happiness." She could not contemplate marrying Beethoven, a commoner, for the simple reason that she would have lost the guardianship of her aristocratic children. Again Therese on Beethoven: "How unhappy, with
