Austrian pianist, teacher, and composer known for his pedagogical (pedagogy) works for the piano.

He studied piano, first with his father, Wenzel Czerny, and later with Ludwig van Beethoven (Beethoven, Ludwig van) and knew and was influenced by Muzio Clementi (Clementi, Muzio) and Johann Nepomuk Hummel (Hummel, Johann Nepomuk). He began teaching in Vienna at age 15; among his pupils were Franz Liszt (Liszt, Franz) and Beethoven's nephew, as well as other celebrated pianists. His published compositions number nearly 1,000 and include ingenious arrangements for eight pianos, four hands each, of two overtures of Gioachino Rossini (Rossini, Gioachino).

Czerny's lasting influence, however, was in his piano studies, which were greatly esteemed by teachers for generations to come. These include the School of Velocity, the School of Virtuosity, and the School of the Left Hand. These exacting sets of graded exercises were still being widely used in the early 21st century. Czerny also left a valuable essay on performing the piano sonatas of Beethoven. He published an autobiographical sketch, Erinnerungen aus meinem Leben (1842; “Memories from My Life”).
