Sophie Brahe (1556–1643)
She was considered one of the most erudite women of her time. Sophie Brahe was the youngest of ten children of Otto Brahe (1518–1571) a State Councilor and Beate Bille (1526–1605). Self-taught and sister of the famous astronomer Tycho, she became his assistant on the island of Hven, which hosted his personal Astronomical Observatory, supported by King Frederick II of Denmark. Indeed, she might have been much more than a simple collaborator, as it is possible that she contributed to the cosmological model known as Tychonic, after the name of the Danish astronomer. She also had a rich private life: she was married twice, and her varied interests ranged from horticulture to medicine, and from alchemy to history.
