Like Scherchen, Felix Mottl (1856-1911) was a well regarded conductor, composer and arranger; much of Mottl’s career was devoted to the works of Richard Wagner. He held posts as the music director for the Ring-Theater in Vienna, the Karlsruhe Opera, and the Munich Opera. He conducted a variety of staged works, including those by Handel, Schubert, Berlioz, Chabrier, and Strauss, but is best remembered for his exceptional interpretations of Wagner’s Ring Cycle, and Tristan und Isolde. In 1911, during his 100th performance of Tristan und Isolde, Mottl collapsed; having suffered a heart attack, he passed away a short time later. Aside from his legacy as a conductor, Mottl also leaves behind a number of arrangements and original compositions, including operas, songs, and two string quartets.
Though I’ve been unable to locate any copies of Mottl’s second string quartet, Gutmann editions of his first quartet are held in Leipzig, and here in Rochester.
