The civil marriage of Emmanuel Mossé and Natasza Goldfain did not take place until March 1920, at the same time as the recognition of the parental legitimacy of their daughter.

In the years between the wars, theatres, painting and photography studios, fashion houses and cabarets offered unprecedented career opportunities for women.

In March 1937, Jean-Louis Barrault staged Numance by Miguel de Cervantes at the Théâtre Antoine in Paris, in which she played the role of Renommée.

[7] As a member of the Surrealist movement around André Breton and Paul Éluard, she was closely associated with Man Ray, Raoul Ubac and Antonin Artaud.

Her blond, summery beauty inspired many photographers such as Man Ray, Juliette Lasserre and Wols, as well as painters such as Alberto Giacometti, Balthus and André Derain, for whom she posed.

There are photographs of this great exhibition taken by Denise Bellon,[10] Raoul Ubac,[11] Pierre Jahan,[12] Gaston Paris,[13] and Georg Reisner,[14] as well as by Man Ray.

They were supported by Francis Picabia, Max Ernst, Alberto Giacometti, Jean Cocteau, Balthus, André Derain and Moise Kisling who provided paintings and drawings to finance the project.

[19] Suzy Solidor, Charles Trenet and Jacques Prévert visited the small stage and with their presence contributed to memorable evenings.

[17] When the Second World War broke out and Paris was occupied by German troops, the cabaret closed its doors and Sonia Mossé and Agnès Capri probably had to leave the French capital.
