A famous bearer was the Cuban-French writer Anaïs Nin (1903-1977), known for her diaries.
This name was fairly popular at the end of the 19th century and beginning of the 20th. The American author F. Scott Fitzgerald used it for the character of Daisy Buchanan in The Great Gatsby (1925). The Walt Disney cartoon character Daisy Duck was created in 1940 as the girlfriend of Donald Duck. It was at a low in popularity in the United States in the 1970s when it got a small boost from a character on the television series The Dukes of Hazzard in 1979.
As a given name, Diana has been regularly used since the Renaissance. It became more common in the English-speaking world following Walter Scott's novel Rob Roy (1817), which featured a character named Diana Vernon. It also appeared in George Meredith's novel Diana of the Crossways (1885). A notable bearer was the British royal Diana Spencer (1961-1997), the Princess of Wales.
The name was common in France during the Middle Ages, and was introduced from there to England, though it eventually became rare. Interest in it was revived by the character Melanie Wilkes from the novel Gone with the Wind (1936) and the subsequent movie adaptation (1939).
