Her career was launched by Jean Cocteau and Jean Paulhan during the Second World War.
Over some sixty years she developed a unique, feminist voice in French novel-writing, blending seamlessly autobiography and fiction, and centered on two men, her first husband, a sculptor, and avant-garde writer and theorist Philippe Sollers with whom, in spite of an age gap, she had a half-century secret relationship.
She was a Femina Prize winner and a member of the Belgian Royal Academy.
