Louis Philippe, comte de Ségur

Louis Philippe de Ségur was born in Paris, the son of Philippe Henri, Marquis de Ségur and Louise-Anne-Madeleine, Marquise de Ségur, née de Vernon (1729–1778). Like his younger half-brother, Joseph-Alexandre Pierre, Vicomte de Ségur, Louis Philippe de Ségur was also born at the family's hôtel particulier in Paris, the Hôtel de Ségur at 9 Rue Saint-Florentin.^[1]

Louis Philippe de Ségur entered the army in 1769 and served in the American War of Independence in 1781 as a colonel under Jean-Baptiste Donatien de Vimeur, Comte de Rochambeau.^[2]

In 1784, he was sent as minister plenipotentiary to Saint Petersburg, where he arrived on 10 March 1785. He belonged to the inner circle of Empress Catherine II and wrote some comedies for her theatre. On 11 January 1787, he concluded a commercial treaty in Saint Petersburg which was exceedingly advantageous to France. On 17 January 1787, he arrived in Tsarskoye Selo to prepare for his journey to Crimea, to which he was invited by Empress Catherine II. The next day, the imperial tour group departed towards the Crimea. In 1789, Louis Philippe de Ségur returned to Paris.^[2][3][4]

Louis Philippe de Ségur took up a sympathetic attitude towards the French Revolution at its outset and in 1791 was sent on a mission to Berlin, where he was badly received. After fighting a duel he was forced to leave Berlin, and went into retirement until 1801 when, at Napoléon Bonaparte's command, he was nominated by the senate to the Corps Législatif. Subsequently, he became a member of the council of state, Grand Master of Ceremonies (1804–1814 and 1815 (Hundred Days)) and a senator in 1813. In 1814 Ségur voted for the deposition of Napoléon and entered King Louis XVIII's Chamber of Peers. Deprived of his offices and functions in 1815 for joining Napoléon during the Hundred Days, he was reinstated in 1819 and supported the Revolution of 1830, but died shortly afterwards.^[2]

Louis Philippe de Ségur married on 30 April 1777 Antoinette Élisabeth Marie d'Aguesseau (1756–1828), who also died in Paris. They had three sons and one daughter:
