Born in Sèvres on March 1879, Jeanne Juliette Marie Bérangère Lassudrie came from a bourgeois family and lived near Notre-Dame, where she stayed for her entire life. Early on, she changed the spelling of her first name, replacing the A in Bérangère with an E. Paule Bayle from the journal La vie féminine recognised her emancipated character as early as 1914 and described her as an independent woman of the time, a true fashion icon.
