Frederick Theodore Albert Delius was an English composer. Born in Bradford in the north of England to a prosperous mercantile family, he resisted attempts to recruit him to commerce. He was sent to Florida in the United States in 1884 to manage an orange plantation. He soon neglected his managerial duties, and in 1886 returned to Europe.

Hélène Sophie Emilie Rosen, later known as Jelka Delius, was a German painter, best known as the wife of the English composer Frederick Delius.
