Antonia Campi, née Antonina Miklasiewicz (10 December 1773 – 1 October 1822) was a Polish operatic soprano.
She quickly became a celebrity in Poland as well as abroad for her unusual voice: she could sing three octaves.
[1] She was invited to perform in Warsaw and also in concerts around Prague, where she settled in 1791, in the company of the impresario Guardoni[2] There she married the first singer of the opera, the bass Gaetano Campi.
[4] At the opening of the new theatre built by Emanuel Schikaneder in Vienna on 13 June 1801, she came to sing the role of Clara in Franz Teyber's opera Alessandro.
The Italian composer Ferdinando Paer wrote especially for her the opera Sargino, ossia l'allievo d'amore (Vienna, 1803).
