(b Przemyśl, 16 Sept. 1891; d Zürich, 17 July 1985). Polish-Swiss composer, pianist, and teacher. After studying in Lemberg (now L′viv), he moved to Vienna, where his teachers included Leschetizky (piano) and Weigl (composition); he also had private composition lessons from Pfitzner in Strasbourg (1913–14). In 1915 he settled in Zürich, forming a friendship with Busoni. Abandoning a promising career as a virtuoso pianist, he became an influential teacher. His first surviving works date from 1911; his last original score was written in 1941, after which he stopped composing: his wife's wealth meant that he did not have to promote his own music, and he interpreted the predictable lack of performances as lack of interest.
