Early in July Beethoven left Montonvasar for Furen, a health resort on the Plattensee, which he reached after a hard trip. Fatigued, grieving over the first parting from Therese, and downcast over his uncertain future, he there wrote the letter to his "Immortal Beloved," which is now one of the treasures of the Berlin Library. It is a long letter, much too long to be given here in full, written for the most part in ejaculatory phrases, and curiously alternating between love, despair, courage and hopefulness and commonplace, everyday affairs. Nor will space permit me to tell how Alexander W. Thayer, an American, who spent a great part of his life and means in gathering detailed and authentic data for a Beethoven biography,—which, however, he did not live to finish,—worked out the year in which this letter was written (Beethoven gave only the day of the month); showed that it must be 1806; proved further that it could not have been intended for Giulietta Guicciardi, yet did not venture to state that Countess Therese Brunswick was the undoubted recipient. Afterward, I believe, he heard of Miriam Tenger, entered into correspondence with her, and the letters doubtless will be found among his papers; but he did not live to make use of the information.

One of the reasons why the identity of the recipient of Beethoven's letter remained so long unknown was that he did not address her by name. The letter begins: "My angel, my all, myself!" In order to secure a fixed position, Beethoven had decided to try Prussia and even England, and this intention he refers to when, after apostrophizing Therese as his "immortal beloved," he writes these burning words:

"Yes, I have decided to toss abroad so long, until I can fly to your arms and call myself at home with you, and let my soul, enveloped in your love, wander through the kingdom of spirits." The letter has this exclamatory postscript:

"Eternally yours!
Eternally mine!
Eternally one another's!"

The engagement lasted until 1810, four years, when the letters, which through Franz's aid had passed between Beethoven and Therese, were returned. Therese, however, always treasured as one of her "jewels" a sprig of immortelle fastened with a ribbon to a bit of paper, the ribbon fading with passing years, the paper growing yellow, but still showing the words: "L'Immortelle à son Immortelle—Luigi."

It had been Beethoven's custom to enclose a sprig of immortelle in nearly every letter he sent her, and all these sprigs she kept in her desk many, many years. She made a white silken pillow of the flowers; and, when death came at last, she was laid at rest, her head cushioned on the mementos of the man she had loved.
