Frederick Delius was an English composer. Born in the north of England to a prosperous mercantile family. He was sent to Florida in the United States in 1884 to manage an orange plantation. There he soon neglected his managerial duties, and in 1886 returned to Europe. Having been influenced by African-American music during his short stay in Florida, he began composing. After a brief period of formal musical study in Germany beginning in 1886, he embarked on a full-time career as a composer in Paris and then in nearby Grez-sur-Loing, where he and his wife Jelka lived for the rest of their lives, except during the First World War.
Delius's first successes came in Germany, where Hans Haym and other conductors promoted his music from the late 1890s. In Delius's native Britain, it was 1907 before his music made regular appearances in concert programmes, after Thomas Beecham took it up. After 1918 Delius began to suffer the effects of syphilis, contracted during his earlier years in Paris. He became paralysed and blind, but completed some late compositions between 1928 and 1932 with the aid of an amanuensis, Eric Fenby.
The lyricism in Delius's early compositions reflected the music he had heard in America and the influences of European composers such as Edvard Grieg and Richard Wagner. As his skills matured, he developed a style uniquely his own, characterised by his individual orchestration and his uses of chromatic harmony. Delius's music has been only intermittently popular, and often subject to critical attacks. The Delius Society, formed in 1962 by his more dedicated followers, continues to promote knowledge of the composer's life and works, and sponsors the annual Delius Prize competition for young musicians.
