Thuillier was an honorary professor at the Collège de France, where he taught history of artistic creation from 1977 to 1998. He was a renowned specialist of French painting and, alongside the late Anthony Blunt, a leading authority on Nicolas Poussin. He donated to the city of Nevers part of his archives, his library, a collection of drawings and engravings, and his collections of photographs, thus making the Nevers Médiathèque into a documentation centre for French painting of the 17th century.
Another part of these archives and manuscripts is held at the INHA (fr), in Paris.
