Pupils of Josef Rheinberger

Gustav Heinrich Ernst Martin Wilhelm Furtwängler (UK: FOORT-veng-glər, US: -⁠lər, German: [ˈvɪlhɛlm ˈfʊɐ̯tvɛŋlɐ]; 25 January 1886 – 30 November 1954) was a German conductor and composer. He is widely regarded as one of the greatest symphonic and operatic conductors of the 20th century. He was a major influence for many later conductors, and his name is often mentioned when discussing their interpretative styles.Furtwängler was principal conductor of the Berlin Philharmonic between 1922 and 1945, and from 1952 until 1954. He was also principal conductor of the Gewandhaus Orchestra (1922–26), and was a guest conductor of other major orchestras including the Vienna Philharmonic.
Although not an adherent of Nazism, he was the leading conductor to remain in Germany during the Nazi regime. Despite his open opposition to antisemitism and the ubiquity of Nazi symbolism, the regime did not seek to suppress him, at Joseph Goebbels' insistence, for propaganda reasons. This situation caused lasting controversy, and the extent to which his presence lent prestige to Nazi Germany is still debated.

Max von Schillings (April 19, 1868 – July 24, 1933) was a German conductor, composer and theatre director. He was chief conductor at the Berlin State Opera from 1919 to 1925.
Schillings' opera Mona Lisa (1915) was internationally successful and was performed at the Metropolitan Opera. The composer married Barbara Kemp, the soprano who sang the title role. Before Mona Lisa, Schillings had already written three operas: Ingwelde (1894), Der Pfeifertag (1899) and Der Moloch (1906).
