 Very rich, but with humorous irony nicknamed "Crozat le pauvre" (Crozat the poor) because his brother Antoine was even wealthier, he was a renowned collector and patron of the arts.His house was at the centre of artistic life for connoisseurs and established as well as up and coming artists.There, Le Gros would certainly have met the ageing Charles de la Fosse who lived with Crozat but also his young protégé Antoine Watteau.
