Through these Malfattis, Beethoven became also known personally to the physician of the same name and “they were great friends for a long time. Towards each other they were like two hard millstones, and they separated. Malfatti used to say of Beethoven: ‘He is a disorderly (~konfuser~) fellow--but all the same he may be the greatest genius.’” The assistant of Malfatti, Dr. Bertolini, was long the confidential physician of Beethoven; and through him he became personally known to the present head of the great firm of “Miller & Co.,” wholesale merchants in Vienna, who for many years was fond of describing his interviews, in youth, with the “great Beethoven.” Though nothing specially worthy of record took place, Mr. Miller’s recollections are interesting as additional testimony to the activity of the master’s mind and his enjoyment of jocose, witty and improving conversation. Through a caprice of Beethoven, his cordial relations to Dr. Bertolini came to an abrupt end about 1815; but the doctor, though pained and mortified, retained his respect and veneration for his former friend to the last. In 1831, he gave a singular proof of his delicate regard for Beethoven’s reputation; supposing himself to be at the point of death from cholera, and being too feeble to examine his large collection of the composer’s letters and notes to him, he ordered them all to be burned, because a few were not of a nature to be risked in careless hands. The reader will not have forgotten Marie Anna Stein of Augsburg--pianoforte-maker Stein’s “Mädl,” as Mozart called her. After the death of her father (February 29, 1792), she, being then just 23 years of age, assisted by her brother, Matthäus Andreas, a youth of sixteen years, took charge of and continued his business. The great reputation of the Stein instruments led to the removal of the Steins to Vienna. An imperial patent, issued January 17, 1794, empowered Nanette and Andreas Stein to establish their business “in the Landstrasse 301, zur Rothen Rose,” and in the following July they arrived, accompanied by Johann Andreas Streicher, an “admirable pianist and teacher” of Munich, to whom Nanette was engaged. The business flourished nobly under the firm-name “Geschwister Stein” until 1802, “when they separated and each carried on an independent business.” It is known that Beethoven, immediately upon the arrival of the Steins, renewed his intercourse with them, of which, however, there is but a single record worth quoting, until a period several years later than that before us. Reichardt writes in his letter of February 7, 1809:
