Willem Mengelberg
Among his notable pupils were Volkmar Andreae, Fritz Brun, Lothar Kempter, Bruno Klein, Jan van Gilse, Hans von Koessler, Karl Aagard Østvig, Ernst von Schuch, and the conductor Willem Mengelberg. Mengelberg controversially claimed that his teacher's ties with Schindler gave Mengelberg a direct connection with Beethoven performance tradition.
