The circumstance that the composer’s new apartments were in the lodging of Count Peter Erdödy strongly suggests the probability that his great intimacy with the Countess dates from the time when he became her near neighbor upon his moving into the Pasqualati house four years before. The close of the letter to Oppersdorff contains the earliest discovered allusion to one of the most singular events in Beethoven’s life. In the autumn of 1807, Jerome Bonaparte, the Corsican lawyer’s youngest son, who had spent his boyhood and youth mostly at sea, and had not yet completed his 23d year, found himself at Cassel, bearing the pompous title of “King of Westphalia.” What could have induced this half-educated, frivolous, prodigal and effeminate young satrap and sybarite to sanction an invitation to his court of the composer most distinguished since Handel for his masculine vigor and manly independence in his art, is one of those small mysteries which seem impenetrable. The precise time when, and by what agency this call was communicated to Beethoven are alike unknown; we only know that before the first of November, 1808, “Beethoven received the same through the High Chamberlain of the King of Westphalia, Count Truchsess-Waldburg, that it was to the office of first Chapelmaster”; and that it led to events, which will be noticed hereafter. The lists of “Arrivals in Vienna” during this season contain the names of several old and new friends of Beethoven, the dates of whose arrival avail in some instances to correct certain current errors. The following seem worth copying: June 1, Joseph Linke, musician, from Breslau; June 23, Count von Brunswick, comes from Pressburg; July 2, Dominik Dragonetti, musician, from Venice [London], comes from Trieste; July 10, Alexander Macco, painter of Anspach, comes from Munich; July 11, Count Rasoumowsky, comes from Carlsbad; August 27, Herr Ferdinand Ries, musical composer of Bonn; Nov. 24, Joh. Fried. Reichardt, Chapelmaster of Hesse-Cassel. [Sidenote: FOUNDING OF THE RASOUMOWSKY QUARTET] In the carefully considered “Übersicht des gegenwärtigen Zustandes der Tonkunst in Wien” of the “Vaterländische Blätter” for May 27 and 31, 1808, it is noted that the violinists Anton Wranitzky and Herr Volta are “in the service of Prince Lobkowitz; Herr Schlesinger in that of the Graf Erdödy; Herr Schmidgen of Count Armadé; Breimann of Esterhazy”; and the like of various performers on other instruments. But no such note follows the name of Schuppanzigh, “who is particularly distinguished among quartet players and probably stands alone as a performer of Beethoven’s compositions.” Nor do the names of Weiss and Linke appear in the article. This of itself is perhaps enough to expose the mistake as to the time when the famous Rasoumowsky Quartet was founded, and to correct the erroneous conclusions drawn from it. But the date of Linke’s arrival in Vienna is proof positive.
