Pierre Crozat (1665–1740) was a French art collector at the center of a broad circle of cognoscenti; he was the brother of Antoine Crozat.
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 HĂ´tel 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.
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.
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.
