One of the leading coloratura sopranos of her generation, she possessed a large, resonant voice with a clear timbre.  Her career took her to the stages of the best opera houses and concert halls in Europe during the first half of the 20th century.  Her signature roles included Gilda in "Rigoletto", Mimi in "La bohème", Rosina in "The Barber of Seville", Violetta in "La traviata", and the title roles in "Lakmé" and "Lucia di Lammermoor".  She also gave lauded concert tours in North and South America. In 1841, while Donizetti was in Paris waiting for the libretto to be completed for a commission by La Scala, he had a chance encounter with Gustave Vaëz, who had co-written the libretti for two of his earlier operas, "Lucie de Lammermoor" (the French version of "Lucia di Lammermoor") and "La favorite".  He asked Vaëz if he could provide a libretto for a short opera to keep him busy while waiting for the La Scala project to advance.  Vaëz quickly created "Deux hommes et une femme" ("Two Men and a Woman"), a comic piece in one act consisting of eight musical numbers connected by spoken dialogue.  According to Vaëz, Donizetti completed the score in eight days.  However, the Opéra-Comique rejected it and Donizetti then had the libretto translated into Italian for an intended performance at the Teatro del Fondo in Naples.  Following the death of the Teatro del Fondo's impresario, Domenico Barbaja, the Naples performance fell through.  The score, still unperformed, was found in Donizetti's effects when he died in 1848. The Bride of Lammermoor is an historical novel by Sir Walter Scott, published in 1819.  The novel is set in the Lammermuir Hills of south-east Scotland, and tells of a tragic love affair between young Lucy Ashton and her family's enemy Edgar Ravenswood.  Scott indicated the plot was based on an actual incident.  "The Bride of Lammermoor" and "A Legend of Montrose" were published together as the third of Scott's "Tales of My Landlord" series.  As with all the Waverley Novels, "The Bride of Lammermuir" was published anonymously.  The novel claims that the story was an oral tradition, collected by one "Peter Pattieson", and subsequently published by "Jedediah Cleishbotham".  The 1830 "Waverley edition" includes an introduction by Scott, discussing his actual sources.  The later edition also changes the date of the events: the first edition sets the story in the 17th century; the 1830 edition sets it in the reign of Queen Anne, after the 1707 Acts of Union which joined Scotland and England.  The story is the basis for Donizetti's 1835 opera "Lucia di Lammermoor".

Lucia di Lammermoor is a "dramma tragico" (tragic opera) in three acts by Gaetano Donizetti.
