First Woman in Math?  Brilliant Life, Tragic Death

Hypatia of Alexandria (approx 360 – 415 AD) is generally considered as the first woman in the history of mathematics – at least the first mentioned.  She is known for this distinction, and for her tragic/brutal death at the hands of Christians.  🙁
