Hummel, John Nepomuk (1778-1837), musical composer and performer, was born at Presburg. He received his early education in music from his father, and was then trained by Mozart. At 10 years of age he accompanied his father on musical tours, and before the end of the century had composed several sonatas, trios, etc. He was then shoir-master for a time to Prince Esterhazy, unci made essays in a more ambitious style of composition. In 1816 he appeared in public as a pianist, and soon won fame, especially by his great powers as an improvisator. The latter part of his life was spent chiefly at Weimar, though he made foreign musical tours from time to time.
