Louise Élisabeth was born in Paris, into the illustrious Croÿ family during the reign of Louis XV. The Duchess's father was the Duke Louis Ferdinand Joseph of Havré and his mother the Princess Marie Louise of Montmorency-Luxembourg. She was married in 1766, at the age of seventeen, to the Marquis de Tourzel. They enjoyed a happy marriage for twenty years, in which Louise Élisabeth bore six children. Her husband was killed in a hunting accident in 1786. She was a staunch supporter of the House of Bourbon, and had this motto engraved on a ring she refused to part with: Lord, save the King, the Dauphin, and his sister!
French Revolution
In 1789, after the fall of the Bastille, many members of the Queen's intimate circle were forced to flee abroad. The Duchesse de Polignac, the queen's favourite and the governess to the royal children, was forced to emigrate to Switzerland. Marie Antoinette appointed Louise Élisabeth to the newly vacant post, with particular attention to be paid to the Dauphin, Louis-Charles. The Marquise was advised to curb the Dauphin's fear of loud noises, particularly the barking of the many dogs at Versailles. From this intimate position, the Marquise de Tourzel was able to watch the disintegration of the Ancien Régime. After an angry mob of hungry women incited by revolutionaries stormed the Palace of Versailles on October 5, 1789, the Marquise accompanied the royal family to live in the Tuileries Palace in Paris. Tourzel's loyalty was strong, and she refused to abandon the royal children as political strife in the nation dramatically increased. She even accompanied the King and his family on a dangerous attempt to flee Paris for a royalist stronghold in Montmédy. This attempt failed, and the entire party was dragged back to Paris by republicans. After the abolition of the monarchy in 1792, Tourzel was separated from the royal family and imprisoned in La Force Prison and the Prison Port-Libre. Also imprisoned at the same time were Tourzel's daughter, Pauline de Tourzel, and Marie Antoinette's personal friend, the Princesse de Lamballe. Shortly after their imprisonment, they found themselves targeted in the September Massacres, when thousands of incarcerated people in Paris were massacred by mobs who were trying to rid the prisons of jailed aristocrats they suspected of treason. Tourzel and her daughter were smuggled out of the prison by a mysterious man, but Lamballe was not so fortunate. She was murdered, and her severed head was then paraded around the city. Tourzel and her daughter were advised by their rescuer, a "Monsieur Hardi", to leave Paris because Pauline had had escaped the prison illegally and was in danger of arrest, and they left for the countryside, were they lived incognito in Vincennes and at the property of her son in Aboundant outside of Dreux. In January 1793, Louis XVI was executed. In October, former Queen Marie Antoinette was also sent to the guillotine. Tourzel was devastated by their deaths, and she was equally shocked to hear of the death of Louis-Charles in 1795. Several times over the coming decades, Tourzel was accosted by various men pretending to be "Louis XVII of France".
Post revolution
As soon as Marie-Therese was allowed visits again by the government, she was among the first who requested to see her in her prison in the Temple. It was Tourzel who informed Marie-Therese that she was to marry her cousin the Louis Antoine, Duke of Angoulême, on the request of the latters father. She attended the wedding of Marie-Therese and Louis Antoine in Mitau in June 1799, and remained in Mitau for some time. Because of her well known sympathy for the Bourbon family, she was put under secret survaillance of emperor Napoleons secret police. During the Bourbon Restoration, Tourzel was made a duchess by a grateful King Charles X. She later published her memoirs, which are an invaluable historical account of the final days of the royal household. Her daughter, Pauline, became a lady-in-waiting to Marie Antoinette's only surviving child, Marie-Thérèse-Charlotte, Duchesse d'Angoulême.
In fiction
The Marquise has featured in several novels about the French Royal family, including Trianon and Madame Royale by Elena Maria Vidal, Flaunting, Extravagant Queen by Jean Plaidy and the Marie Antoinette romances by Alexandre Dumas, père. The character of the Marquise de Tourzel appeared in the 1956 French film Marie-Antoinette reine de France.
