Czerny, Karl (1791-1857), pianist and composer, and son of a professor of music, was born at Vienna. At the age of ten he showed such proficiency that he was taken in hand by Beethoven as well as by Sebastian Bach and Clementi. But for much of his life he gave all his energies to his pupils, some of whom achieved brilliant success, and though he published at thirteen, his productive powers slept till he was forty, when he made up for lost time, and produced no less than 800 pieces. He also wrote a Practical School of Composition, and an Outline of a History of Music.
