Albertine-Elisabeth Pater

She was the daughter of the Dutch baron Johann Gisbert von Neukirchen or Nyvenheim (1705-1792) and Margriet van Wijhe (1714- ?

By the allowance and inheritance from her spouse, which was founded on diamond mines and slave plantations in Dutch Suriname, she was very rich.

She was at one point the lover of minister Étienne François, duc de Choiseul, who collaborated with the Emmanuel-Armand de Richelieu, duc d'Aiguillon to depose the king's mistress Madame Dubarry by arranging an affair between the king and Pater and suggest that he enter into a secret morganatic marriage with her.

Through her personal friend Diane de Polignac, she became a member of the private circle of Marie Antoinette at Trianon.

After the release, she resumed her activity as an agent and financier of the exile French royalist émigrées, taking her orders from the count of Artois.
