Eléonore Denuelle de La Plaigne

Louise Catherine Eléonore Denuelle de la Plaigne (13 September 1787 – 30 January 1868) was a mistress of Emperor Napoleon I of France and the mother of his son Charles, Count Léon.

She was born Louise Catherine Eléonore Denuelle de la Plaigne into a middle-class family, by reports of the day she was pretty and witty, and was married at the age of 18 to a former army captain, Jean-François Revel-Honoré.

Shortly afterward she became a mistress to the Emperor Napoleon, an arrangement set up by his sister Caroline Bonaparte, and in less than a year their illegitimate son, Count Léon, was born.

In 1808, Napoleon arranged a marriage for her to a young lieutenant, Pierre-Philippe Augier of Sauzay, in order to end the royal affair.

She was paid a hefty dowry by the emperor, and the newly married couple departed for Spain.
