Born to the tenor Valentin Adamberger and the actress Maria Anna Jacquet, she was raised after the death of her parents by the poet Heinrich Joseph von Collin.
Debuting at the age of sixteen on New Year's Day 1807 at the Burgtheater, she was immediately engaged as a Court Actress [1] and "straightway found great acclaim as an ingénue, in both sentimental and some tragic parts.
"[1] Antonie Adamberger quickly became the darling of the Viennese public, displaying her abilities as Beatrice in The Bride of Messina and also as Desdemona and Emilia Galotti.
Beethoven composed Klärchen's songs "Die Trommel gerühret" ("The drum is a-stirring") and "Freudvoll und leidvoll" ("Joyful and woeful") (first introduced at the Burgtheater on June 15, 1810) in his incidental music for Goethe's Egmont with Adamberger specifically in mind.
In 1817, some years after the poet's untimely death, Adamberger abandoned the stage and married the antiquary and numismatist Joseph Calasanza von Arneth.
