Ludwig van Beethoven, Billet an Nannette Streicher, Baden, Anfang September 1824, Autograph

Beethoven informs Nannette Streicher that he would like to see Streicher's new instrument the next day, he will discuss a definite time with her in person in the afternoon. He asks her to be patient: in his current situation he is not able to act in the way he normally does, "although I am still called Beethowen".

At the beginning of the 19th century Nannette Streicher and her husband Johann Andreas Streicher ran the most famed Viennese piano making company. From 1823 onwards their son Johann Baptist was a partner in his mother's company. At the beginning of September 1824 Beethoven had looked at the new "Patent-Pianoforte" by Johann Baptist Streicher. 15 years prior to this the composer had already given the father Johann Andreas Streicher advice on how to improve his pianos.
