Biography
Sylvie Pétiaux-Hugo was born in Valenciennes, Nord on November 28, 1836. She was the daughter of Casimir-Joseph Pétiaux and Marie-Stéphanie Hugo. She claimed to be related to Victor Hugo, but this seems to be an invention. Her sister was Zélie-Rosalie Pétiaux, an opera singer, wife of Count Mikhaïl Illarionovitch Moussine-Pouchkine, and her niece was Olga Illarionova Moussine-Pouchkine, a violinist with the Russian imperial theaters, who became the master of a Martinist lodge in Russia. Camille Flammarion will also be linked to Gérard Encausse, known as "Papus".She married Esprit Mathieu on December 31, 1859 in Paris. In 1874, she married the astronomer, Camille Flammarion with whom she had been having an affair for several years. He took her in a balloon for their honeymoon.
Pétiaux shared the same interest for astronomy as her husband. She remained for many years a devoted and assiduous collaborator in all of his work. It is at her initiative that the, rewarding eminent services rendered to the Société astronomique de France, was established. In Paris, Pétiaux hosted the popular salon des étoiles.
In 1889, she was the founder and active promoter of an association of women advocating peace and disarmament, L'Association la Paix et le Désarmement par les femmes. It was the third women's peace society established in Paris. Run only by women and with only women speakers, its emphasis was on the dangers associated with the arms race. She was a speaker at the Universal Peace Congress of 1907 in Munich.
Under the pseudonym of "Sylvio Hugo", she authored her husband's biography, Camille Flammarion, sa vie et son oeuvre : à propos des fêtes de Montigny-le-Roi, and also wrote a novel.
She died of the Spanish flu in the 14th arrondissement of Paris on February 23, 1919, at the age of 82 years. Her tomb is located in the park of the Camille Flammarion Observatory of Juvisy-sur-Orge.
