composer and organist who helped introduce the music of J.S. Bach (Bach, Johann Sebastian) into England. The son of Charles Wesley, the hymn writer, and the nephew of John Wesley, the founder of Methodism, he began an oratorio, Ruth, at the age of 6 and at age 11 published Eight Lessons for the Harpsichord. Though he suffered from 1787 onward from an injury to his skull, he became one of the finest organists and extemporizers of his time. With K.F. Horn he published an English edition of Bach's Das Wohltemperierte Klavier (The Well-Tempered Clavier). A man of wide culture, he also won renown as a conductor and lecturer. His many compositions include symphonies, concerti, services, anthems, and motets, of which Exultate Deo and In exitu Israel are outstanding.
