Portrait of Monsieur Bertin is an 1832 oil-on-canvas painting by Jean-Auguste-Dominique Ingres. It depicts Louis-François Bertin (1766–1841), the French writer, art collector and director of the pro-royalist Journal des débats. Ingres completed the portrait during his first period of success; having achieved acclaim as a history painter, he accepted portrait commissions with reluctance, regarding them as a distraction from more important work. Bertin was a friend and a politically active member of the French upper-middle class. Ingres presents him as a personification of the commercially minded leaders of the liberal reign of Louis Philippe I. He is physically imposing and self-assured, but his real-life personality shines through – warm, wry and engaging to those who had earned his trust.
