Claire Démar

[3] The couple's daughter named Demar Theresia (Thérèse), harpist and composer (who was her elder sister) was born in Gernsbach, (Germany) in 1786.

She used the Saint-Simonian movement to go further and express findings and claims that were rejected by a majority of her contemporaries, but became accepted by feminists during following years.

Shortly before her death, she published a Appel d'une femme au peuple sur l'affranchissement de la femme ("Appeal of a woman to the people on the enfranchisement of women") which calls for the application to women of the Declaration of the Rights of Man and of the Citizen.

Démar was preparing to publish a second book, she committed suicide with her lover Perret Desessarts.

They were found on the same bed with two letters and a roll of paper, which she had asked to be read in the Saint-Simonian society of Paris and then given to Barthélemy Prosper Enfantin, who sent the papers to Suzanne Voilquin who published them in La Tribune des femmes.
