She was nicknamed "Miss Bessy" at court as an anglophile, not regarded beautiful or clever, but fascinated the king by refusing his advances.

[1] She accepted on condition that the queen's consent should be gained to a left-handed marriage with the King to ease her conscience.

[1] She was married to Frederick in a ceremony in the chapel of Charlottenburg Palace on 7 April 1787, and was given the title Countess Ingenheim.

[1] She died of consumption, two months after giving birth to a son, Gustav Adolf Wilhelm.
