Unsterbliche Geliebte
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."
