Louis Hesselin

The latter signed his name Louis Hesselin as early as 1623 and regularised the change by lettres patentes, registered with parlement on 19 December 1626.

Not long after, Louis Hesselin obtained the office of maître de la chambre aux deniers [Master of the Chamber of Funds].

While there he may have taken the opportunity to acquire a large number of books, paintings, and objets d'art, documented much later in an inventory made after his death.

He also owned a country house, the Maison Chantemesle (in what is now the Parc Chantemerle), in Essonnes on the road between Paris and the Palace of Fontainebleau.

At Chantemesle he entertained French royalty and foreign travelers, including John Evelyn in 1644 and Queen Christina of Sweden in 1656.
