Badass History Ladies - Hypatia of Alexandria

“Reserve your right to think, for even to think wrongly is better than not to think at all.”

Said to have been the last librarian of the Library of Alexandria, Hypatia is the first recorded female mathematician. She edited works of science and math, and invented the hydrometer (a device which helps measure the gravity and density of liquids).

There are two accounts of her death. The first, and most widely accepted, was written soon after her dead in 415 CE. According to the historian, Hypatia was murdered by a Christian mob for her political influence and heresy.
