Maria Sibylla Merian

Maria Amalia of Austria
Maria Amalia was born an Austrian Archduchess in Hofburg Palace, Vienna; about eleven weeks after the death of her infant brother Leopold Joseph, her parents' only son. Her mother was unable to conceive more children after Maria Amalia, supposedly because her father had contracted syphilis from one of his mistresses and passed the disease to his wife, rendering the Empress infertile. Maria Amalia's father had a long line of mistresses, both servants and nobles, and several illegitimate children. Her mother Wilhelmine Amalia of Brunswick-Lüneburg was the sister of the Duchess of Modena and a very pious woman.
