Arcadie Meyer, Baroness of Eppinghoven, born Marie-Anne Arcadie Eugénie Claret^{[citation needed]} (30 May 1826 – 13 January 1897),^{[citation needed]} was a Belgian noblewoman and the mistress of Leopold I, King of the Belgians for more than twenty years,^[1] causing a national scandal.

Marie-Anne Arcadie Eugénie Claret was born on 30 May 1826 in Brussels, Kingdom of Belgium as the daughter of Major (later Lieutenant colonel) Charles-Joseph Claret (1789–1867), treasurer of the Pension Fund for Widows and Orphans of the Belgian Army.^{[citation needed]} She had twelve siblings.^{[citation needed]} The Claret family lived in a mansion in the middle of a park in Etterbeek.^{[citation needed]}

Claret met Leopold I, King of the Belgians (1790–1865) between 1842 and 1844.^{[citation needed]} Depending on the exact date of their meeting, she was between the ages of 15 and 18, and he was between 51 and 54. Soon, she became his mistress, and was moved into a luxurious house on the Rue Royale/Koningsstraat in Brussels.^{[citation needed]} Their affair could not remain secret and was widely discussed in the Belgian press.^{[citation needed]}

In order to reduce negative media attention towards his mistress, the king married Claret to the master of the royal stables, Ferdinand Meyer^{[citation needed]} (1808–1864), a widower with three children. He acknowledged the king's two illegitimate sons by his wife (both born during the course of the marriage) as his own.^{[citation needed]}

On 14 November 1849 in Liège, Meyer gave birth to a son, George Georges-Frédéric Ferdinand Meyer (1849–1904).^{[citation needed]} In 1850, she moved to Wiesbaden, Electorate of Hesse to escape the public scrutiny that had grown unbearable.^{[citation needed]} After the king's wife, Queen Louise (1812–1850) died, Meyer returned to Brussels in 1851 and started to conduct herself and her affair more discreetly.^{[citation needed]} She moved out of the house on the Rue Royale and bought the Château of Stuyvenberg with the king's financial aid. Her new home was closer to the royal family's residence, the Palace of Laeken, and Leopold visited her and their children almost every day.^{[citation needed]} On 25 September 1852, Meyer had a second son, Arthur von Eppinghoven (1852–1940).^{[citation needed]}

The relationship of Arcadie Claret/Meyer and King Leopold lasted until his death on 10 December 1865, for 20 to 23 years. The king wanted to secure the position and livelihood of his mistress and children after his death. In 1851, he sold Meyer an estate in Monheim am Rhein, Kingdom of Prussia with a house and 170 hectares (420 acres) of land.^{[citation needed]} The estate had previously been the farm of the nearby abbey called Eppinghoven.^{[citation needed]} King Leopold wanted to bestow a title on his unofficial family and create them barons of Eppinghoven, which the Belgian parliament refused to approve.^{[citation needed]} In the end, in 1862, Leopold's nephew, Ernest II, Duke of Saxe-Coburg-Gotha granted the hereditary title to two sons, and in 1863 to their mother, too.^[2] Arcadie and Ferdinand Meyer separated in 1861.^{[citation needed]}

The Baroness d'Eppinghoven had started building a castle in Monheim am Rhein in 1862, where she retired following the death of the king, seeing that she was no longer welcome in Belgium.^{[citation needed]} She died on 13 January 1897, 31 years after Leopold I.^{[citation needed]}
