He retired to Switzerland in 1934, and died in Vevey.
His works include sonatas for viola, cello, winds, and three for violin (the third was recorded on a multi-LP set called Musik zwischen den Kriegen : eine Berliner Dokumentation), four symphonies (including one in manuscript) and also a chamber symphony, four string quartets, several piano trios, piano quartets and piano quintets as well as one sextet for piano and strings from 1902 and a wind quintet, a number of concerted works including three violin concerti and a triple concerto with piano trio, many piano works and lieder, and a number of stage works including an opera Aleko.
