Dresden archive
The possibility of previously unknown early Mahler works emerged when, in 1938, the Dutch conductor Willem Mengelberg revealed the existence of an archive of manuscripts in Dresden, in the hands of Marion von Weber, with whom Mahler had been romantically involved in the 1880s. Mengelberg claimed that these manuscripts included drafts of four early symphonies, which he and the German composer Max von Schillings had played through on the piano.
