 Busoni acknowledges receipt of a packet of Schenker's compositions. He suggests
    that Schenker might combine three of the piano pieces into a single three-section work. He will

OJ 9/6, [19] Handwritten letter from Eugen d'Albert to Schenker, dated June 11,
                1897
 Eugen d'Albert suggests his opera "Rubin" might be better suited to the
                Viennese public than "Gernot," which he considers an advance on the former. He asks
                Schenker for his reservations about "Gernot." He raises a question about Schenker's
                piano "Fantasie", Op. 2.

OJ 6/7, [8] Handwritten letter from Schenker to Moriz Violin, dated February 14, 1924
 Schenker reports continuing trouble with Hertzka, especially over delays to the
    publication of Tonwille 5 and 6, which were supposed to appear the previous year, and is
    beginning to think about legal action. Hertzka has made his position so difficult that he feels
    obliged to turn down Max Temming's offer of direct financial support for his work. He asks
    Violin to help find a post in Hamburg for Carl Bamberger, a gifted pupil who, though he
    neglected his piano studies for a while, is keen to make up for lost time. Finally, he asks if
    Violin received any of the four volumes of the Beethoven piano sonata edition.
