Arturo Toscanini
Arturo Toscanini (25 March 1867 – 16 January 1957) was an Italian conductor. Most musicians think he was the greatest conductor of his time.  His fame was legendary: he was probably the first conductor to become a world superstar.  He had an incredibly good memory and could remember every single note of the large number of works he conducted.  He had a photographic memory so that he could remember what the pages looked like.  Sometimes he found little mistakes in the scores which no one else had ever noticed.  He had a very keen sense of hearing and knew exactly what each instrument was doing.  He also had a fiery temperament and there are movies of him shouting angrily at his orchestra in rehearsals.  In the early days of gramophone recordings he made some of the first recordings of famous orchestral works.
