OJ 10/3, [7] Handwritten letter from Otto Erich Deutsch Deutsch to Schenker, dated January 16, 1920

Deutsch will write to the Beethoven House in Bonn to seek permission to reproduce the manuscript of the "Moonlight" Sonata. He suggests using the first edition as the source for the missing opening and closing bars, and asks Schenker to refrain from polemics in his commentary. Copies of the manuscripts of Beethoven's piano sonatas Opp. 28, 109, 110 and 111 should not be difficult to obtain, and he has made inquiries regarding the manuscripts of Beethoven's Piano Sonata Op. 106 and Mozart's A minor Rondo K. 511.
