Antoine de Seguiran

Antoine de Seguiran, called chevalier de Seguiran, was an 18th-century French soldier and encyclopédiste. De Seguiran was from a military family from Arles. In October 1766, he married Pauline Le Breton, a former fiancée to Beaumarchais.

Chevalier de Seguiran wrote two articles for the Encyclopédie by Diderot and D'Alembert: Vérité (truth) and Vertu. Diderot added the sensualist point of view on the latter.
