Jérôme Phélypeaux

Jérôme Phélypeaux (March 1674 – 8 February 1747), comte de Pontchartrain, was a French politician, son of Louis Phélypeaux.

He served as a councillor to the parlement of Paris from 1692, and served with his father as Secretary of State of the Maison du Roi and Navy Minister from 1699 onwards. His management of the French Navy was criticised, but recent historiography has reevaulated his contributions. He directed a significant programme of explorations and encouraged the settlement and development of Louisiana. He was responsible for the creation of the Académie des Inscriptions et Belles-Lettres.

His first marriage, in 1697, was with Éléonore Christine de La Rochefoucauld de Roye (known as Mademoiselle de Chefboutonne) (1681–June 1708). Five children were born to this marriage:

He remarried in July 1713 with Hélène de L'Aubespine (1690–1770), with whom he had two daughters.

In 1715, with the death of Louis XIV and the assumption of power by the Regent, Phélypeaux was compelled to resign his ministries in favour of his son Jean-Frédéric. Effective authority, and later the guardianship of his children, passed to his kinsman Louis Phélypeaux, marquis de La Vrillière.
