Vienna, 1798. Age 27.

Two staves of music sketched in brown ink in Beethoven's hand, hurried, with corrections
A sketch in his hand. Detail of BH 116, Beethoven-Haus Bonn: working notes toward the Bagatelle WoO 59, some years later than this date. It is the earliest working paper of his that can be freely reproduced here; the paper of 1798 looked like this. Public domain.
Piano Sonata No. 8 in C minor, op. 13, composed 1798. First movement, Grave — Allegro di molto e con brio.

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.

From 1818. The conversation books.

An open conversation book, two small pages of pencil handwriting
Conversation book D. 10, folio 44 and following, February 1823. Berlin State Library. Public domain. This leaf is one of the rarer kind: the hand is his. He is answering Anton Schindler about a former pupil, in French, because they were in a public place and he did not want the room to hear. Most leaves are the other way round: a friend's question in pencil, and then nothing, because he answered out loud.

He stood beside the conductor, Michael Umlauf, beating time into music he could not hear; the players had been told to follow Umlauf.the accounts agree on this

Caroline Unger took his sleeve and turned him around to face the hall.whether after the scherzo or at the end, the accounts differ

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.
