Fulvia was born in Geneva, into an aristocratic German Baltic family. Before the 2nd World War, Fulvia's father, Guy von Hahn and his wife were deeply impacted by the Oxford Group, and was working as a journalist in the German press agency. To stand against the Nazi regime was to risk your life and that of your family: a close friend was murdered by the Gestapo. He joined the National Socialist party to protect his family, and to the end of his life questioned that decision. The von Hahns lost their home when the Red Army overran Germany’s eastern territories in 1945.
She married Pierre Spoerri in 1958. Together they travelled the world with Moral Re-armament. They also became pillars of the Caux conference centre.
Fulvia was a brilliant linguist and translated a number of books.
