The history of Beethoven’s Bonn life would be so sadly imperfect without the “Notizen” of Dr. Wegeler, which bear in every line such an impress of perfect candor and honesty, that they can be read only with feelings of gratefullest remembrance of their author and with fullest confidence in their authenticity. But no more in his case than in others can the reminiscences of an aged man be taken as conclusive evidence in regard to facts and occurrences of years long since past, when opposed to contemporary records, or involving confusion of dates. Some slight lapse of memory, misapprehension, or unlucky adoption of another’s mistake, may lead astray and be the abundant source of error. Still, it is only with great diffidence and extreme caution that one can undertake to correct an original authority so trustworthy as Dr. Wegeler. Such corrections must be made, however; for only by this can many a difficulty be removed. An error in the Doctor’s chronology might easily be occasioned by the long accepted false date of Beethoven’s birth, insensibly influencing his recollections; and certainly when Dr. Wegeler, Madame von Breuning and Franz Ries, all alike venerable in years as in character, sit together discussing in 1837-8 occurrences of 1785-8, with nothing to aid their memories or control their reminiscences but an old Court Calendar or two, they may well to some extent have confounded times and seasons in the vague and misty distance of so many years; the more easily because the error is one of but two or three years at most. Bearing upon the point in question is the fact that Frau Karth--who distinctly remembers the death of Madame van Beethoven--has no recollections of the young Breunings and Waldstein until after that event. Some words of Dr. Wegeler in an unprinted letter to Beethoven (1825): “inasmuch as the house of my mother-in-law was more your domicile than your own, especially after you lost your noble mother,” seem to favor the usually accepted chronology: but if Beethoven was thus almost a member of the Breuning family as early as 1785 or 1786, how can the tone of the letter to Dr. Schaden be explained? Or how account for the fact, that, when he reached Bonn again and found his mother dying, and his father “in a very unfortunate state” and “compelled to sell a portion of his effects and pawn others and knew not what to do,” it was to Franz Ries he turned for aid? The good Doctor is certainly mistaken as to the time when Beethoven found Mæcenases in the Elector and Waldstein; why not equally so in relation to the Breuning family?
