(b Constantinople, 13 Dec 1785; d Berlin, 29 May 1838). Austrian soprano. She was brought up in Constantinople and Bucharest, before moving to Vienna, where she studied with Giuseppe Tomaselli and Antonio Salieri (on Emanuel Schikaneder's recommendation) and also had instruction from Sigismund Neukomm (on Joseph Haydn's advice). She made her début as Juno in F. X. Süssmayr's Der Spiegel von Arkadien (1803), and sang Leonore in all three versions of Ludwig van Beethoven's Fidelio (1805, 1806 and 1814). Her voice was described by Haydn as ‘like a house’ and by G. A. Griesinger as ‘like pure metal’.
