About the year 1770 Duke Karl began to undergo a change of heart. Wearying at last of life's vanities and frivolities, the middle-aged sinner took up virtue and philanthropy, as if to show mankind that he too could be a benevolent father to his people. The new departure was due in part to the political success of the Estates in curbing his extravagance, but rather more, no doubt, to the personal influence of his mistress, Franziska von Hohenheim. This lady, whose maiden name was Bernerdin, had been given in marriage as a girl of sixteen to a worthless Baron von Leutrum, who misused her. Escaping from him with thoughts of divorce in her mind, she went to visit friends in Ludwigsburg. Here the inflammable duke fell in love with her, and, after a not very tedious resistance, carried her away to his castle. This was in 1772. Her divorce followed soon after, and she remained at court as the duke's favorite mistress. He presently procured for her an imperial title, that of Countess Hohenheim, and after the death of his duchess, in 1780, he married her. She was not beautiful or talented, but she possessed amiable qualities that made and kept her the object of Karl's honest affection. She knew how to humor his whims without crossing his stubborn will, and she chose to exert her influence in promoting humane enterprises and leading her liege lord in the paths of virtuous frugality. On the whole, the people of Württemberg, who had suffered much from mistresses of a different ilk, had reason to bless their ruler's fondness for his amiable 'Franzele'. She was not unworthy to sit for the portrait of Lady Milford.
