In 1916 he became professor of advanced pianoforte classes at the Warsaw Conservatory, and continued to teach there until his death in 1971. He assisted in establishing the International Chopin Piano Competition, and served upon their juries from the first occasion, 1927, until 1971. After the Second World War, and especially after the death of Józef Turczyński (1884–1953), he was considered the greatest Polish piano teacher.
