Betty Vio

[2][3] One contemporary source puts her age in 1812 as nine years old, meaning she would have been born in 1802 or 1803.

[4] Her father is usually named as the Italian noble Francesco Vio,[2] but the fact that she was born in Lübeck makes it more likely that her parents were (Georg Friedrich) Wilhelm Vio and Philippine Vio (né Dupont) who were engaged in Lübeck from 1799 to 1809 and performed with Betty beginning in 1810 at the Bergisches Theater in Düsseldorf.

[3] In 1829, she was hired at the Berlin Court Opera as a replacement for Henriette Sontag but followed her first husband Josef Spitzeder, whom she married in 1831, to Munich in 1832.

[5][1] After his death, she returned to Berlin, where their daughter Adele Spitzeder was born.

[5][1] She later married Franz Maurer and moved to Graz and had some engagements at the Carltheater in Vienna.
