From what I heard I could come to the conclusion that in some manner he must have offended the lady and was trying to make amends by an exhibition of good humor. At last he jumped up and shouted: “Why, all those things are by me!” I had played nothing but movements from his works, connecting them with short transition-phrases, which seemed to please him. The lady soon went away and to my great amazement Beethoven did not know who she was. I learned that she had come in shortly before me in order to make Beethoven’s acquaintance. We followed her in order to discover her lodgings and later her station. We saw her from a distance (it was moonlight),[22] but suddenly she disappeared. Chatting on all manner of topics we walked for an hour and a half in the beautiful valley adjoining. On going, however, Beethoven said: “I must find out who she is and you must help me.” A long time afterward I met her in Vienna and discovered that she was the mistress of a foreign prince. I reported the intelligence to Beethoven, but never heard anything more about her either from him or anybody else. The rehearsal at Schuppanzigh’s on “Wednesday” (18th) mentioned in the letter of July 14th, was for the benefit of Ries, who was to play in the first of the second series of the regular Augarten Thursday concerts which took place the next day (19th) or, perhaps, the 26th. Ries says on page 113 of the “Notizen”: Beethoven had given me his beautiful Concerto in C minor (Op. 37) in manuscript so that I might make my first public appearance ~as his pupil~ with it; and I am the only one who ever appeared as such while Beethoven was alive.... Beethoven himself conducted, but he only turned the pages and never, perhaps, was a concerto more beautifully accompanied. We had two large rehearsals. I had asked Beethoven to write a cadenza for me, but he refused and told me to write one myself and he would correct it. Beethoven was satisfied with my composition and made few changes; but there was an extremely brilliant and very difficult passage in it, which, though he liked it, seemed to him too venturesome, wherefore he told me to write another in its place. A week before the concert he wanted to hear the cadenza again. I played it and floundered in the passage; he again, this time a little ill-naturedly, told me to change it. I did so, but the new passage did not satisfy me; I therefore studied the other, and zealously, but was not quite sure of it. When the cadenza was reached in the public concert Beethoven quietly sat down. I could not persuade myself to choose the easier one. When I boldly began the more difficult one, Beethoven violently jerked his chair; but the cadenza went through all right and Beethoven was so delighted that he shouted “Bravo!” loudly. This electrified the
