Eleanor Erdmuthe Louisa, born a Princess, the daughter of the Duke of Saxe-Eisenach, had married the Margrave of Ansbach, John Frederick. When he had died, Eleanor and three-year-old Caroline had been turned out of the household and took up a poor wandering life among diverse minor courts of northern Europe. The center of gravitation round which they looped, and to which they frequently returned, was the court of the Elector and Electress of Brandenburg-Prussia, in Berlin. And a fine choice it was, for the Electress, Sophie Charlotte, had made of it a fair and fascinating place, replete with savants (e.g., Leibniz), writers, artists, musicians, &c. Sophie Charlotte and her redoubtable Mum, the Electress Sophie of Hanover, had taken Eleanor and Caroline under their wings, and been good to them.
