Henriette L'Hardy

Henriette L'Hardy (1766–1808) was a Swiss painter.

L'Hardy was the daughter of an officer in the French military, and was friends with Benjamin Constant. She was a disciple of Isabelle de Charrière, with whom she exchanged over 160 letters beginning in 1791, and whose papers she inherited. She was a companion of Sophie von Dönhoff before marrying the historian Louis-Henri-Eusèbe Gaullieur. The couple had a son, Eusèbe-Henri, later a historian as well, but she died soon after his birth. A self-portrait, described in various sources as a pastel or as a painting, still exists in a private collection.
