As a daughter from a house of lower nobility, Katharina was first transferred to a monastery, from where she, inspired by Luther's writings, broke out together with eight fellow sisters and fled to Wittenberg. There she married Martin Luther in 1525, with whom she had six children. Her economic skills transformed the initially precarious situation of the Luther family into an economically stable household. However, her influence was not limited to her domestic and family activities; she also stood by her husband in theological questions with clever and quick-witted answers. Full of affection and respect she called Luther “my Lord Käthe”.
