“ Köchel sensibly remarks that the trouble lay in Beethoven's 'aversion to the enforced performance of regular duties, especially to giving lessons, and teaching the theory of music, in which it is well known his strength did not lie, and for which he had to prepare himself.' When the untamed nature of Beethoven, and his deafness, are considered, together with his lack of worldly wisdom and his absolute need of a Mæcenas, one feels deeply how fortunate he was to have attracted and retained the sympathy and affection of a man of such sweet and tender qualities as Archduke Rudolph. ”
