Reichardt was born in Potsdam, the youngest of the six children of violinist and composer Franz Benda (1709–1786), who was concert master at the court of Frederick II.
Her older sister Maria Caroline Wolf (née Benda) (1742-1820) was later also a well-known singer, pianist and composer.
After her marriage with Johann Friedrich Reichardt, the couple moved to Berlin, from there onwards to Hamburg, Weimar and Königsberg.
[3] Since 1733, Franz Benda was in the service of the Prussian Crown Prince, later Frederick II, who initially resided in Ruppin and after his enthronement in Potsdam in 1740.
He was well-received by the entire family, and made him hear many things that further strengthened his love and respect for the great Benda school.
The wedding of the couple took place on 23 November 1776 and was obviously an event of great importance in Berlin, which was still a few months later, in the educated circles.
She was later to follow in the footsteps of her father and her mother, and as a song composer, vocal pedagogue, and chorus, which she was given great prestige.
