Note 125 — Chapter XIV

Dr. Leopold Sonnleithner, in the “Recensionen” of Vienna (1861. p. 592), corrects a mistake in an obituary notice of Chapelmaster Gläser with the remark: “I can very well remember that the opera (‘Fidelio’) was rehearsed and conducted by Josef Weigl.” Dr. Sonnleithner’s authority is justly so decisive in all matters pertaining to the musical annals of Vienna, and even the slightest errors are so very rare in his writings, that if one occurs it must be corrected upon unimpeachable authority, to prevent its passing into history. Now, in the manuscript text-book above cited, is written below the list of properties: “Herr Umlauf, conducts”; and near the end of the manuscript overture to “Fidelio” stands in Beethoven’s hand: “Indicate to Umlauf where the trombones enter.” Treitschke is thus so fully confirmed as to leave no doubt that in this instance Dr. Sonnleithner’s memory played him false.
