George Enescu
Romanian composer, violinist, pianist, conductor, and teacher, 1881-1955
"Pablo Casals described Enescu as ""the greatest musical phenomenon since Mozart"" and ""one of the greatest geniuses of modern music"". Yehudi Menuhin, Enescu’s most famous pupil, once said about his teacher: ""He will remain for me the absoluteness through which I judge others ... Enescu gave me the light that has guided my entire existence."" He also considered Enescu ""the most extraordinary human being, the greatest musician and the most formative influence"" he had ever experienced. Vincent d’Indy claimed that if Beethoven’s works were destroyed, they could be all reconstructed from memory by George Enescu. Alfred Cortot, one of the greatest pianists of all time, once said that Enescu, though primarily a violinist, had better piano technique than his own."
