Ignaz Jakob Holzbauer (18 September 1711 – 7 April 1783) was an Austrian composer of symphonies, concertos, operas, and chamber music, and a member of the Mannheim school.
Despite the opposition of his parents, who intended him for the law, he studied music, and in 1745 became kapellmeister to Count Rottal and at the Court Theatre of Vienna.
[1] His operas include Il figlio delle selve, which was the opening performance of the Schlosstheater Schwetzingen in 1753.
Its success led to a job offer from the court at Mannheim, Germany, 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.
[1] 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.
