[1] At seventeen she left for Paris, where she found a job in commerce while posing as a model for artists, among them Alberto Giacometti.

Making up for her lack of formal education, she took an active interest in music, literature and the arts, frequenting literary circles and becoming familiar with writers such as Louis Aragon, Georges Bernanos and Jean Giraudoux.

[2] In 1926, she met Albert Béguin, a Swiss literary scholar specializing in German Romanticism who would become a renowned essayist, critic and translator.

She continued to write several novels, such as Blanche (1939), Elisabeth (1943), Les noces du matin (1950) and La couronne des innocents (1962); none of these, however, reached the acclaim of Campagne.

After the war, Vincent divorced Béguin; while the latter was on his deathbed in 1957, she travelled to Italy, where he then lived, to bid him farewell.
