Together with Louise Bodin, Reynaud founded the newspaper La Voix des femmes on October 31, 1917,[2] to promote women's right to vote.
[3] Reynaud managed the newspaper while Bodin assumed the role of editor-in-chief,[4] attracting the participation of celebrities such as Séverine, Madeleine Pelletier, Hélène Brion, Henri Barbusse, and Marcel Cachin.
The newspaper was launched in the middle of the World War I in a context of repression, symbolized in November 1917 by the arrest of the teacher Hélène Brion, accused of defeatist propaganda.
[5] In 1930, Marguerite Durand referred to Reynaud as one of the "remarkable professionals" of women's journalism of her day, noting that she kept more to a management than to an editorial role.
[5] In October 1920, Reynaud also joined the Action Committee for the release of imprisoned militants, notably Fernand Loriot, Boris Souvarine, and Pierre Monatte.
