The brothers Crozat were born in Toulouse, France, the sons of modest merchants. He and his brother Antoine were opportunistic, self-made men, rising from obscurity to become two of the wealthiest merchants in France. Pierre was known as Crozat le pauvre, to distinguish him from his even-wealthier brother.
Pierre Crozat was one of the most prominent French financiers and collectors, becoming the treasurer to the king in Paris in 1704, when he built the Hôtel de Crozat on the rue de Richelieu and began gradually acquiring a notable collection of paintings, old master drawings, and objets d'art. He was the principal patron of Antoine Watteau, who painted for his dining room, a suite of Four Seasons, and of other early Rococo artists. Pierre Crozat's collection of old master drawings was already one of the most important in France at the beginning of the 18th century.
From 1714 until the purchase was finally concluded in 1721, he worked as agent and negotiator for the Regent, Philippe II, Duke of Orléans, on the purchase in Rome of the art collection of Queen Christina of Sweden for the Orleans Collection.
Between 1729 and 1742, a finely-illustrated, two-volume work was published, known as the Cabinet Crozat, (also known as "Recueil Crozat") including some of the finest paintings in French collections. Many of his old master drawings, catalogued by Pierre-Jean Mariette, one of the four acknowledged expert connoisseurs in Paris, were dispersed at auction in Paris in 1741. That occasion was termed by Michael Jaffé as "the greatest public sale of drawings held in the dix-huitième."
Most of Crozat's treasures were inherited by his nephews, Louis François (d. 1750), Joseph Antoine (d. 1750), and Louis Antoine (d. 1770), who added to the collection. The works of art were dispersed after the nephews' deaths. Louis Antoine Crozat's collection was bought in 1772, through Denis Diderot, by Catherine II of Russia and went to the Hermitage Museum in Saint Petersburg.
