Question: Klindworth took up the position of professor of pianoforte at a conservatory in what country? Passage:In 1854 Klindworth went to London, where he remained for fourteen years, studying, teaching and occasionally appearing in public. From London Klindworth went to Moscow in 1868, following Nikolai Rubinstein's invitation to take up the position of professor of pianoforte at the Moscow Conservatory, where he first met Pyotr Ilyich Tchaikovsky as professor of harmony. While in Russia he completed his pianoforte arrangements for Wagner's Der Ring des Nibelungen, which he had commenced during Wagner's visit to England in 1855, Beethoven's sonatas and also his critical edition of Frederic Chopin's works. He then became conductor of the Berlin Philharmonic in 1882, in association with Joseph Joachim and Franz Wullner, being also the conductor of the Berlin Wagner Society. At this time, he established the Klindworths Musikschule, which later became the Klindworth-Scharwenka Conservatory.
