"Johann Adam Hiller (25 December 1728, in Wendisch-Ossig, Saxony – 16 June 1804, in Leipzig) was a German composer, conductor and writer on music, regarded as the creator of the Singspiel, an early form of German opera. In many of these operas he collaborated with the poet Christian Felix Weiße.
Furthermore, Hiller was a teacher who encouraged musical education for women, his pupils including Elisabeth Mara and Corona Schröter. He was Kapellmeister of Abel Seyler´s theatrical company, and became the first Kapellmeister of Leipzig Gewandhaus." - (en.wikipedia.org 30.01.2020)
