Hanna Solf

Johanna Susanne Elisabeth Solf (née Dotti, 14 November 1887 – 4 November 1954) was a member of the German resistance to Nazism and key member of the Solf Circle.
Johanna Dotti married Wilhelm Solf in 1908, who was then governor of German Samoa. Lagi von Ballestrem (born So'oa'emalelagi Solf in 1909) was their eldest child. Starting in 1928 they lived in Berlin, where Wilhelm died in 1936.
Hanna Solf and Elisabeth von Thadden frequently hosted tea parties for intellectuals opposed to the Nazi government, a group which would later be called Solf Circle (). They would make plans how to enable victims of Nazi persecution to flee the country.
After the betrayal of the Solf Circle by Paul Reckzeh, its members were arrested by the Gestapo. Hanna Solf was detained on 12 January 1944 and ultimately brought to Ravensbrück concentration camp. While several members of the group were executed, Solf and her daughter were freed before their trial when the Red Army liberated Ravensbrück.
