UNGER, MAX (1883–1959), musicologist. Born in Germany, Unger worked as a conductor and critic, and in 1919–20 edited the Neue Zeitschrift fuer Musik. In 1933 he went to Switzerland and Italy and returned to Germany after World War ii. An authority on Beethoven, he published Auf Spuren von Beethovens unsterblicher Geliebten (1911), Beethovens Handschrift (1926), Ein Faustopernplan Beethovens und Goethes (1952), and the catalogs of two important Beethoven collections. Unger gathered material for a revised edition of Beethoven's letters and established many of their datings for the first time.
