Marie-Noémi Cadiot (French: [kadjo]; 12 December 1828,[1][2] Paris – 10 April 1888, Saint-Jean-Cap-Ferrat), also known as Noémi (or Noémie) Constant and her literary pseudonyms Claude Vignon and H. Morel, was a French sculptor, journalist and writer of the 19th century.
Cadiot left Constant in the early 1850s for Marquis Alexandre de Montferrier, brother-in-law of Messianist philosopher Józef Maria Hoene-Wroński,[3] and had the marriage annulled in 1865.
In the late 1850s she had a liaison with architect Hector Lefuel, from which a son was born in 1859 whom she called Louis Vignon.
[7][8] She attended the Mrs Niboyet's Women's Club, and wrote in the Le Tintamarre and Le Moniteur du Soir soaps under the literary pseudonym of Claude Vignon (a character from a novel by Honoré de Balzac), which was formalised in 1866.
[9] Cadiot published Contes à faire peur in 1857, Un drame en province - La statue d'Apollon in 1863,[10] Révoltée!,[11] Un naufrage parisien in 1869,[12] Château-Gaillard in 1874,[13] and Victoire Normand in 1862.
