Drzewiecki was born in
Warsaw. He commenced study under his father, and then, at Warsaw, under Oberfeldt and Pilecki. After he had matriculated he went (from 1909 to 1914) to
Vienna to the atelier of
Theodor Leschetizky, where he studied with
Marie Prentner, the master's assistant. He gave many recitals in Polish towns, and also in Vienna,
Prague and
Berlin. 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. ==Students==
