 In addition to the "Dessoff'scher Frauenchor" (first concert in 1907 at Dr. Hoch's Konservatorium), which quickly became famous throughout Germany, she also directed the "Frankfurter Bachgemeinde" for several years and in 1918 founded one of the first madrigal ensembles in Germany.During the time that Margarete Dessoff lived in Frankfurt, the Dessoff family home was across the street from the aunt and uncle of the American banker Felix Warburg.As a boy, Mr. Warburg came to know Margarete Dessoff from visits to his uncle's house, and it was this friendship which moved him to bring her to America for a holiday following the strain of the First World War.
