Born in Vienna, the daughter of the Viennese teacher Carl Fröhlich and his wife Antonie[1] received her first music education from her father.
[3] On 20 March 1901, Fröhlich appeared at the Dresden Court Opera from the cycle Homeric World under the direction of Ernst von Schuch.
At the London Covent Garden Opera, Fröhlich sang in Wagner's Ring of the Nibelung under the direction of Gustav Mahler the Rhinemaidens, Erda and a Valkyrie.
As a singer, she took part in church concerts, for example in Chemnitz with the aria: Se i mici Sospiri, which was attributed to Alessandro Stradella, and with the song Sei stille dem Herrn from Mendelssohn's Elija.
[9][10] After her marriage in 1901, Fröhlich took the name of her husband, the later Viennese district inspector[11] Otto Kolbe,[12] and ended her professional career as an opera singer in Dresden.
