Carl Czerny was an Austrian composer, teacher, and pianist of Czech origin whose music spanned the late Classical and early Romantic eras. His vast musical production amounted to over a thousand works and his books of studies for the piano are still widely used in piano teaching. He was one of Ludwig van Beethoven's best-known pupils and would later on be one of the main teachers of Franz Liszt.
