Trilby by George Du Maurier  
Trilby  is a novel by George du Maurier and one of the most popular novels of its time. Published serially in 
Harper’s Monthly from January to August 1894, it was published in book form on 8 September 1895 and sold 200, 000 copies in the United States alone.
Trilby is set in the 1850s in an idyllic bohemian Paris. Though 
Trilby features the stories of two English artists and a Scottish artist, one of the most memorable characters is Svengali, a rogue, masterful musician and hypnotist.
Trilby O’Ferrall, the novel’s heroine, is a half-Irish girl working in Paris as an artist’s model and laundress; all the men in the novel are in love with her. The relationship between Trilby and Svengali forms only a small, though crucial, portion of the novel, which is mainly an evocation of a 
milieu.
Lucy Sante wrote that the novel had a ‘decisive influence on the stereotypical notion of bohemia’ and that it ‘affected the habits of American youth, particularly young women, who derived from it the courage to call themselves artists and ‘bachelor girls, ‘ to smoke cigarettes and drink Chianti.’
The novel has been adapted to the stage several times; one of these featured the lead actress wearing a distinctive short-brimmed hat with a sharp snap to the back of the brim. The hat became known as the trilby and went on to become a popular men’s clothing item in the United Kingdom throughout various parts of the 20th century, before enjoying a revival as a unisex clothing item in the United States in the 2000s.
