Max Ernst Unger (28 May 1883, in Taura – 1 December 1959, in Zurich) was a German musicologist.
Although he wrote on a variety of subjects, he is chiefly known for his extensive research and writings on the life and works of Ludwig van Beethoven.
After serving in World War I, he worked as editor of the New Journal of Music in 1919 and 1920.
From 1932 to 1939, he lived in Zurich and catalogued the valuable Beethoven collection of local industrialist Hans Conrad Bodmer, which was later bequeathed to the Beethoven House in Bonn.
[1][2] His job was to catalogue sheet music seized from Jews in occupied Paris, including the personal collection of escaped harpsichordist Wanda Landowska.
