Belgian composer Joseph Jongen (1873-1953).
From his teens to his seventies he composed a great deal, including symphonies, concertos, chamber music (notably a late string trio and three string quartets), and songs, some with piano, others with orchestra. (His list of opus numbers eventually reached 241, but he destroyed a good many pieces.) Today, the only part of his oeuvre performed with any regularity is his output for organ, much of it solo, some of it in combination with other instruments
