ERNST, HEINRICH WILHELM German violinist and composer, was born at Briinn, Moravia, on May 6, 1814, and was educated at the conservatorium of Vienna, study ing the violin under Joseph Bohm and Joseph Mayseder, and com position under Ignaz von Seyfried. In 1832 he went to Paris, where he formed an intimacy with Stephen Heller, which resulted in their charming joint compositions-the Pensees fugitives for piano and violin. In 1843 he paid his first visit to London. The impression which he then made as a violinist was more than confirmed in the following year, when his rare powers were recognized by the musical public. After a long illness, he died at Nice, Oct. 8, 1865. As a violinist Ernst was distinguished by his great mastery of technique, loftiness of conception, and intensely passionate ex pression. He wrote, in addition to many fantasias and salon pieces for the violin, a concerto (F sharp minor) of great technical diffi culty which is still sometimes heard, and two string quartets.
