Arnail François, marquis de Jaucourt

Madame de Staël obtained his release from Louis Pierre Manuel just before the September Massacres.

[2] Jaucourt took refuge in Switzerland to escape the Reign of Terror, and returned only after Napoleon Bonaparte's 18 Brumaire coup and the establishment of the French Consulate, entering the tribunate, of which he was the president for a short period.

[3] In 1803, Jaucourt entered the French Senate, and next year, upon the establishment of the First Empire, he became attached to the household of Joseph Bonaparte.

During the following years, Jaucourt distanced himself from the imperial cause, and, with the Bourbon Restoration he became Minister of State and a Peer of France.

After the outcome of the Hundred Days (during which he stood by Louis XVIII), he was Naval Minister in July–September 1815, but held no further office.
