Max von Schillings (April 19, 1868 – Berlin, 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). Source : Wikipedia
