Joseph Czerny (June 17, 1785, Hořovice - January 7, 1842, Vienna) was a Bohemian composer, pianist, and piano teacher. Among his compositions is variation number 5 for Part II of the
Vaterländischer Künstlerverein. Among his pupils were Leopoldine Blahetka (1809–1885) and
Ludwig van Beethoven's nephew, Karl. His variations were not well received by the English magazine
The Harmonicon: "His variations, seven in number, have nothing new in them; they pursue the same track that has been beaten for many years past, and have, under various names, nauseated the ear during a long quarter of a century at least."
