W. H. Wilkins, Caroline the Illustrious, vol. 1… (1901)
“ Leibniz often met the Princess of Ansbach at the Queen of Prussia’s reunions, and he noted how high she stood in the favour of his royal mistress. He became attracted to her by her wit and conversation, which were unusual in a princess of her years. He spoke of her in glowing terms to the Electress Sophia, who later made acquaintance with the young princess at Berlin, and she, too, was charmed with her talents and beauty. Leibniz, who was much at Berlin in those days, kept his venerable mistress at Hanover acquainted with the movements of the princess. ”
