Only really "known" outside Holland (if at all) for two works- a piano quintet and an orchestral rhapsody - but the NMI archives (see link), Worldcat, etc. list some other music (opera (Kalte Herz), Introduction & Scherzo for orchestra, piano works, piano quartet, overture, variations, ...) that maybe wants looking at, at least. Can't seem to find a manuscript source for the piano quintet but NMI may not be the one who has it :)
