The two girls made their first appearance at a concert; Stich sang a duet from Norma with the singer Amalie Haehnel.
King Friedrich Wilhelm III supported the family by allowing performances by the young girls at the Königsstädtisches Theater.
Stich was then taught by the choral director Elsler and from 1838 was a member of the Sing-Akademie zu Berlin, where she also appeared in solo roles.
She is said to have played a Gretchen "such as the public had never seen before and will never see again, not a sentimental little doll; but a girl of flesh and blood, hearty and pithy",[2] a Clärchen, which had been convincing as a "heroine in bourgeois dress", and the model image of a queen in the Don Carlos.
Grothe indicated that even after this second marriage, the actress's life was not easy: "To the honour of humanity, let us assume that her opponents did not want to wound her to death", we read in his Erinnerungsblatt an die zu früh gestorbene Künstlerin, and: "[H]ad she not possessed a finely constructed artist's soul, many an insult would have passed imperceptibly for her, which thus became a nail in her early coffin.
"[6] Clara Liedtcke tried to recover during the theatre holidays in 1862 in Reichenhall and returned apparently healthy, but soon fell ill again.
Stich died in Berlin at the age of 42 and was buried on 4 October 1862 in the Cemetery II of the Jerusalems- und Neue Kirchengemeinde [de] in front of the Hallesches Tor.
[7] Wilhelm Grothe, in his Erinnerungsblatt, compared the actress to a female Correggio of the stage: "There was nothing garish, nothing repulsive, no adverse angles and corners - a holy virginity transfigured even the commonplace, the eternal femininity held even the demonic enclosed.
