Christiane Magdalena Elisabeth Haßloch

In 1786, the sisters joined the theatre company of Gustav Friedrich Wilhelm Großmann and Christian Wilhelm Klos. Under the music director August Burgmüller the company gave its performances in the larger Rhineland cities, notably Cologne, Düsseldorf, Bonn and Aachen.[3] The company broke up in 1787. Diring the 1789/90 season she played at the Bonn Court Theatre which had re-opened in January 1789,[3] and where the young Ludwig van Beethoven played the viola in the theatre orchestra.[4]

By May 1790 she had left Bonn and joined the National Theatre in Mannheim where she made her debut as Constanze, the lead role in Mozart's opera, Seraglio. She remained at Mannheim until April 1792, when she moved to Amsterdam to undertake some engagements at the German Theater. Leaving Mannheim at short notice involved breaking her agreement, and she was obliged to pay a contractual penalty of 100 ducats when she returned to Mannheim in August 1792. In 1793, she went back to Amsterdam, this time accompanied by the tenor Karl Haßloch whom she married.[3]

Between 1795 and 1804, she worked with her husband in Kassel. They went on a tour of Germany, after which, in 1809, she withdrew completely from theatre work for a year. She then moved to the newly created Darmstadt Theatre, where she worked as a singer and actress, where she was appointed Court Actress ("Hofschauspielerin "). She withdrew to private life, this time permanently, in 1818.[1]
