Kleinheinz, Franz Xaver

Franz Xaver Kleinheinz (26 June 1765 – 29 January 1832) was an Austrian composer, piano teacher and Kapellmeister.

Born in Nassenbeuren [de] near Mindelheim, Kleinheinz first went to Munich and in 1799 to Vienna, where he met Beethoven and soon became a sought-after piano teacher. His pupils included Giulietta Guicciardi and the sisters Therese Brunsvik and Josephine Brunsvik. From 1805, he took up a second residence in Brno and in August 1810 he was appointed as Kapellmeister in Bratislava. At the beginning of May 1813, it is said that Kleinheinz, "one of the most excellent piano players", had resigned from his post in Pressburg and returned to Vienna. From 1814 to 1824, he worked as a conductor at the Deutsches Theater in Pest.

Kleinheinz died in Pest at the age of 66.
