Lucrezia Aguiari

Lucrezia Aguiari (sometimes spelled Agujari) (1743/46 in Ferrara – 18 May 1783 in Parma) was an Italian coloratura soprano. She possessed an unusually agile voice with a large vocal range that spanned slightly more than three and a half octaves; faculties that enabled her to perform the most difficult passage work. In a letter dated 24 March 1770 Leopold Mozart wrote of hearing her perform a C an octave above high C at the Ducal opera of Parma, "I could not believe that she was able to reach C soprano acuto, but my ears convinced me." Aldous Huxley also mentioned this event in his novel, "Brave New World", (misspelt as 'Ajugari').
Biography.
Born in Ferrara, during her lifetime Aguiari was often referred to as "La Bastardina" or "La Bastardella". There are several different traditions explaining the origin of this nickname, one being that she was the illegitimate child of Leopoldo Aguiari or that of his wife with the "Marchese" Bentivoglio. Another possible explanation was that she was an abandoned child raised by Aguiari. Another curiosity about the soprano was that she possessed a pronounced limp that was reportedly the result of a dog or hog eating part of her leg while she was an infant.
Aguiari studied with Brizio Petrucci in Ferrara and then was further educated at a convent in Florence, where she received 
singing lessons from Abbé Lambertini. In 1764 she made her professional opera debut in Florence and the following year made appearances at the opera houses in Padua, Lucca and Verona. In 1766 she appeared in Genoa, Lucca, and Parma; ultimately becoming a Court singer in the latter city in 1768. That same year, in Naples, she sang the title role at the world premiere of Paisiello's "Le nozze di Peleo e Tetide", (on the occasion of the wedding ceremony of King Ferdinand IV of Naples and the Two Sicilies and Archduchess Maria Carolina of Austria). She also had several great successes in Milan, Paris, and London. There is no documentation to support reports that she was involved romantically with the composer Josef Mysliveček during her early career, in spite of many reports that appear in musicological literature. No mention of a love affair with Mysliveček pre-dates the publication of the fifth edition of the "Grove Dictionary of Music and Musicians" (1954).
In 1780 Aguiari married the composer Giuseppe Colla (1731–1806). She left the stage after the close of the summer opera season at Genoa in 1782 due to ill health. Although it was rumoured that she was poisoned by a jealous rival, she actually died of tuberculosis in 1783 at the age of 40.
