Here, beyond what has already been said, I will limit myself to saying that, humanly speaking, I am very sorry because there was something spirited in him that made me like him, despite everything.
Politically we were poles apart; musically he had some insights - I am referring to Beethoven - sometimes shareable and sometimes not.
Of course, that attitude of his was unbearable: "everyone stop, here I come, I've understood everything while the others understand nothing."
But that's how it is! people must be taken for who they are and... anyway, in a certain sense, he will be missed by me too, if only for what he taught me about Fidelio.
I will also limit myself to writing a few words. I met him once and we wrote to each other regarding his book on Beethoven; he is a person who perhaps, in terms of character, seems a bit peculiar and "rude" at first, but with me, he was incredibly kind and cultured, even with the idea of being the "greatest" recent biographer of Beethoven (and not only).
He spoke to me about his book which occupied him for many years, despite there being points (sometimes many) that I do not share, such as his way of expressing himself and criticizing other writers.
