Joseph-Alexandre Pierre de Ségur, Viscount of Ségur

He hired the architect Perrard de Montreuil to build a house at the rue Chantereine to host his mistress Louise Julie Careau.

[4] In 1793, Ségur was imprisoned during The Terror period of the French Revolution in the prisons of Saint-Lazare, as were André Chénier and other artists of the time.

La Buissière destroyed the accusation file for Ségur along with those of many other personalities of the Parisian scene, saving their lives.

Ségur died at the age of 48 in the company of Mademoiselle d'Avaux, his mistress of twelve years, while he was recovering from a chest illness at Bagnères-de-Bigorre.

His last posthumous publication, the memories of the baron de Besenval, his assumed father, provoked a scandal in society at the time.
