Vienna, 1798. Age 27.
1801. To Franz Gerhard Wegeler, in Bonn.
… my ears whistle and buzz continually, day and night. I can say I am living a wretched life. For almost two years I have ceased to attend any social functions, just because I find it impossible to say to people: I am deaf. If I had any other profession it would be easier, but in my profession it is a terrible handicap.
… I beg you to keep what I have told you about my hearing a great secret, to be confided to nobody, whoever he may be.
Ludwig van Beethoven to Franz Wegeler, Vienna, 29 June 1801. The letter itself is held by the Beethoven-Haus, Bonn. No freely reproducible photograph of it exists; the words are given here in translation.
Heiligenstadt, 6 October 1802. To his brothers. Found in a drawer after his death, twenty-five years later.




The Heiligenstadt Testament, facsimile of the four leaves. Hamburg State and University Library. Public domain. Almost nobody can read the hand comfortably; the passage most people come for is on the first leaf, and reads:
… how could I possibly admit an infirmity in the one sense which ought to be more perfect in me than in others, a sense which I once possessed in the highest perfection …
… it seemed to me impossible to leave the world until I had brought forth all that I felt was within me.
In translation. He was thirty-one.

He answered aloud. What he said is not on the page. A hundred and thirty-nine of the books survive: half of every conversation he had for the last nine years of his life, in other people's handwriting.

Recordings. Op. 13, first movement: a performance released to the public domain (CC0). Op. 125, fourth movement: Musopen, CC BY-SA 3.0. Both are recordings available to you today. Sound on this page is withdrawn at the point in the record where it stopped being available to him; nothing here attempts to reproduce what he heard, at any stage. We do not know that.
The conversation on the blank leaf is invented. The books are real; 139 survive; his side of them does not, because it was spoken. The accounts of the premiere differ on exactly when Caroline Unger turned him; every account agrees on the turn and on the handkerchiefs.
