However, the claim that he destroyed all his works from the early 1910s, made at the Orgelconcerten page, is not quite, anyway, true; the substantial list of manuscripts at NMI (see external links, below) contains e.g. an autograph of a "Strijkkwartet/17-2 1911" - presumably(?) the string quartet mentioned. At least one song ("Avant que tu l'en ailles/Pâle étoile du matin, / Paul Verlaine. / Musique de / Bernh. Meyer / 2 sept. 1912" survives from this period, and some works dated 1915; however his "Op.1" is attached to "Van de Bloemen" of 1917.
