She made her first public appearance as a singer at the age of 16 and the following year was engaged by the Mannheim Opera. There seems to be some debate whether she first performed in
Gassmann's in May 1772, or
Sacchini's , the role for which she earned the title of court musician (). She stayed with the Mannheim court opera for four years and was cast in the premier roles: Parthenia in
Schweitzer's
Alceste (1775,
Schlosstheater Schwetzingen), and Anna in
Holzbauer's (1777), a role composed specifically for her voice. At twenty-one, she travelled to London to sing four opera series by
J. C. Bach and Sacchini. In 1778, she married the
oboe virtuoso and composer
Ludwig August Lebrun (1752–1790) from Mannheim. That summer, now known as Signora Lebrun, she toured Italy with Ludwig. At the opening of the
Teatro Alla Scala in
Milan on 3 August 1778, Francesca Lebrun was the female lead in
Antonio Salieri's opera . She created a sensation in 1779 in Paris at the
Concert Spirituel through her ability to fit Italian words to instrumental parts of symphonies concertantes and sing them. The Lebruns lived in London from 1779 through 1781 while Francesca appeared at the
King's Theatre. In 1780, the celebrated English artist
Thomas Gainsborough painted her portrait. A celebrated coloratura soprano, she sang on major operatic and concert stages through Europe, including England, Germany and Italy, to great acclaim. The musician and writer
Christian Friedrich Daniel Schubart noted that she could sing A, three octaves above middle C with "clarity and distinctness".
Charles Burney wrote that when she and her husband performed divisions of thirds and sixths it was impossible to discover who was uppermost of the interval. == Family ==
