(1782-1837) Irish-born composer and pianist. Often regarded as one of a group of composers known as the London Pianoforte School, all of his works include the piano, reaching their peak artistically with his nocturnes, a genre he named and devised. These anticipate Chopin's nocturnes by 20 years, especially regarding their forward-looking textures and passage work.
As an apprentice to Muzio Clementi, he traveled throughout Europe demonstrating instruments for the firm of piano makers established by his master. He settled in St Petersburg 1803, where he composed most of his mature music.
