Elsa 'Jack' von Reppert-Bismarck, (1903 - 1971), painter ('neuen deutschen Frau' and kunstmalerin).
She was born Elisabeth Meyer, in Berlin on 10 February 1903 and died at Herkenrath near Cologne on 21 July 1971.Von Reppert became a bit of an 'it' girl celebrity, as shown by the coverage given her by Weimar Republic era magazines such as Die Dame, Das Leben and UHU in the late 1920s.
Subsequently and concurrently she went to New York and England.
It isn't clear what happened during the years of war and the peace afterwards though she and her husband both died at or near his family's West German seat.
