Jean de Noailles

Jean de Noailles, 5th Duke of Noailles (Jean Louis Paul François; 26 October 1739, Paris20 October 1824) was a French nobleman and scientist.

Early life Jean-Louis-Paul-François de Noailles was the son of Catherine de Cossé-Brissac and Louis, 4th duc de Noailles, a Marshal of France in 1775. His father was a nephew of Marie Victoire de Noailles, daughter-in-law of Louis XIV, and his paternal grandmother, Françoise Charlotte d'Aubigné, was a niece of Madame de Maintenon.

He was in the army for a period. However, his eminence as a chemist gained him the election as a member of the Académie des sciences in 1777. He was also a Knight of Golden Fleece.

He became Duc d'Ayen in 1766 on his grandfather's death, and Duc de Noailles on his father's in 1793. Having emigrated in 1792, he lived in Switzerland until the Bourbon Restoration in 1814, when he took his seat as a Peer of France. The Duke learned of their deaths weeks later. His family had lost many other members including two of his uncles (including Philippe de Noailles, duc de Mouchy) and numerous cousins and in-laws during the Revolution.

The Duke went into self-imposed exile in Switzerland until the Bourbon Restoration, returning to France and his ravaged estates after Napoleon and the Directory restored some order. Through the efforts of his daughter Adrienne de La Fayette, whose husband's family also suffered greatly in the Revolution, some part of his once immense fortune was restored.

On 25 February 1755, he was married to heiress Henriette-Anne-Louise d'Aguesseau, the daughter of Jean Baptiste Paulin d'Aguesseau de Fresne, Count of Compans and of Maligny, and Anne Louise Françoise du Pré, Dame of la Grange-Bleneau. It was an arranged marriage, worked out by Adrien-Maurice, 3rd duc de Noailles, as Henriette was heiress to the fortune of her paternal grandfather, Henri François d'Aguesseau, a three-time Chancellor of France. Jean and Henriette lived at the family residence in Paris, the Hôtel de Noailles on Rue Saint-Honoré, and were the parents of eight children:

Adrien Paul Louis de Noailles (1756–1757), who died in infancy. Anne Jeanne Baptiste Louise de Noailles (1758–1794), who married her cousin the Louis-Marie, the Vicomte de Noailles. Marie-Adrienne-Françoise de Noailles (Nov. 2,1759–1807), who married Gilbert Du Motier, Marquis de Lafayette. A daughter (born and died 11 December 1760), who died upon birth. Françoise Antoinette Louise de Noailles (1763–1788), who became the Comtesse de Thezan du Pourjol. Anne Paule Dominique de Noailles (June 22, 1766 – 1839), who became the Marquise de Pouzols, Marquise de Montagu. Angélique Françoise d'Assise Rosalie de Noailles (1767–1833), who became the Marquise de Grammont. Louis Gabriel de Noailles (1768–1770), who died in infancy.

Although the Duke remarried in 1796 to the Baroness Wilhelmine Justine of Mosheim (Yury Golovkin's mother), he had no further children and was survived by only two of his eight children. Having no surviving sons and having survived his nephews, he was succeeded as Duc de Noailles by his then 22 year old grandnephew, Paul de Noailles.
