Marie-Adélaïde Hadot, known under the name Barthélemy-Hadot, née Richard (15 June 1763 – 19 February 1821) was an early 19th-century French novelist and playwright.
The daughter of the choral vicar of the collegiate church of Saint-Étienne, Marie-Adélaïde married a schoolmaster named Barthélémy Hadot on January 11, 1785.
Hadot embraced with warmth the party of the Revolution, became municipal officer and a member of the Revolutionary Committee.
Although he showed some moderation in performing these jobs, the school found himself completely abandoned after the fall of Robespierre [fr] and the couple was forced to take refuge in Paris.
She soon became a widow and had no other resources to live than to engage in literary works in which she gave herself without reserve, while holding a small boarding school that had little success.
