Ignaz Jakob [Ignaz] Holzbauer (18/09/1711 - 07/04/1783), an Austrian composer, born in Vienna. He was a composer of symphonies, concertos, operas, and chamber music, and a member of the Mannheim school. His aesthetic style is in line with that of the Sturm und Drang "movement" of German art and literature. His operas include Il figlio delle selve (premiered Schwetzingen, 1753). Its success led to a job offer from the court at Mannheim, where he stayed for the rest of his life, continuing to compose and to teach, his students including Johann Anton Friedrich Fleischmann (1766-1798), the pianist, and Carl Stamitz. Holzbauer died in Mannheim, Germany. His opera Günther von Schwarzburg, based on the life of the eponymous king (and described here), was an early German national opera, a performance of which Mozart and his sister attended, through which they met Anton Raaff, who was later to premiere a role in Idomeneo. Mozart also composed nine numbers for insertion in a Miserere by Holzbauer on commission by the Parisian Concert Spirituel in 1778, but they have been lost. They have been given the catalog number KV 297a in the list of Mozart's works.
