He became a State Councillor in 1721, Minister to the King of Prussia at the French Court in 1722, was made a Baron in 1737, and in 1740 was elevated to the rank of Envoy Extraordinary and Minister Plenipotentiary, and awarded the Order of Generosity. At the heart of Paris-Berlin exchanges, he embodied the international openness of French-speaking Switzerland. This important portrait of Jean de Chambrier, painted during a stay in Paris in 1723, is documented in the same year by a payment of 500 livres for "M. Chambrier de Neuchâtel, minister to the King of Prussia". With its sober composition and sumptuous rendering, the work illustrates the art of Hyacinthe Rigaud, at its height in the 1720s: moiré light, lace and changing taffeta are rendered with exceptional virtuosity. The artist's expression conveys the elegance, authority and stature of a high-ranking diplomat. Once completed, the work was turned into an engraving by Schmidt. The life of Baron de Chambrier is also linked to his sumptuous home. Château d'Auvernier, built in 1559 and acquired by Pierre Chambrier in 1603, embodies more than 400 years of family history. It has been passed down from generation to generation, notably by the Sandoz-Rollin, Pourtalès and Montmollin families. Over the centuries, it has been home to captains in the service of France, Savoy and the United Provinces, governors of the Principality of Neuchâtel, a chamberlain to the King of Prussia and state councillors. According to tradition, this portrait has remained in the family since it was commissioned in 1723 and added to the Château d'Auvernier collections. This centuries-old provenance gives it exceptional status. A rare combination of pictorial quality and historical importance, the portrait of Jean de Chambrier is a benchmark of Rigaud's work and a milestone in Swiss heritage.
