[1] She had one sister, Charlotte Ackermann, and one stepbrother Friedrich Ludwig Schröder via her mother.

Born in Gdańsk (Danzig),[2] Royal Prussia, she entered the stage at the age of four in the role of Annabella in Lessing's Miss Sara Sampson.

She left the stage in 1778 and married Johann Christoph Unzer, who was a noted doctor and poet in Altona.

[3] After her marriage, she stopped appearing on the stage and chose instead to take part in upper-class urban life, which she could only now do as the wife of a renowned doctor.

Her stepbrother acquired and destroyed all of the court documents that Unzer had allowed to be created.
