(b Vienna, 17 Sept. 1711; d Mannheim, 7 April 1783). Austrian composer and conductor. Largely self-taught, he developed his composing skills by directing the music at the Burgtheater in Vienna. After three years in Italy with his wife, the singer Rosalie Andriedes, he moved to Stuttgart and then Mannheim (1753–78). Here he wrote his most important opera, Günther von Schwarzburg (1777), a pioneering German grand opera both in its choice of a German historical theme and in the fluency of much of its handling and its expressive orchestration. It was admired by Mozart, and influenced him in a number of specific ways (including in Idomeneo and Die Zauberflöte). Holzbauer also composed much interesting church and chamber music.
