She wrote under the name Jean Dominique.She was born in Brussels and was educated under the system of education developed by Isabelle Gatti de Gamond.
She chose to write under a male "nomme de plume" so that her work would be judged on its own merits; the name came from a character in a novel by Eugène Fromentin.
Her poems were first published in small literary magazines and later in the Mercure de France.
