The Life of Ludwig van Beethoven…
“ The service which Karl gave his uncle seems frequently to have been given grudgingly and no doubt looked more ungracious than it may really have been, when accompanied by protests that he would not be found failing in duty and petulant requests that he be spared upbraidings and torments. To satisfy the singular mixture of affectionate solicitude and suspicion which filled Beethoven’s heart and mind would perhaps have taxed the philosophy of a wiser as well as gentler being than this young man, who, as Johann’s wife told the composer in Gneixendorf, had inherited the testy family temper. ”
