Maria Sibylla Merian

Maria Sophia of Neuburg
Maria Sophia was born at the Schloss Benrath outside Düsseldorf in what is now Germany. Her father Philip William was the reigning Count Palatine of Neuburg. In 1685 he became Elector Palatine following the death of his cousin Charles II, an inheritance that greatly increased the family's status within Europe. In December 1676, Maria Sophia's sister Eleonore Magdalene was married to Holy Roman Emperor Leopold I owing to the family's reputation as producing fertile women. After two marriages, Leopold had no living male heirs. The new Empress Eleonore Magdalene fulfilled her function and quickly mothered two future Holy Roman Emperors (Joseph I and Charles VI).
