Who is the "Immortal Beloved"? Could it be Baroness Dorothea von Ertmann, described by both Schindler and Kapellmeister Reichardt as "a beautiful tall woman of noble appearance and soulful countenance"? Reichardt speaks of "such strength united with the most intimate tenderness... a soul sang at the end of each of her fingers" especially when it came to Beethoven's compositions. "She was often able to bring our Grand Master to great admiration" Schindler wrote of Dorothea's regular appearances on the Sunday matinees organized by Carl Czerny where Beethoven himself was frequently present. Schindler is especially impressed by the incomparable way in which the Baroness interpreted the Sonata dedicated to her, Opus 101, of which she was able "to grasp Beethoven's most hidden intentions, as if they had been written under her eyes.".
