Hypatia of Alexandria

Hypatia was the daughter of Theon, a mathematician of Alexandria, and she surpassed her father to become the most celebrated scholar of her age. In a world that gave women little room for learning, she led the Neoplatonic school of the great city, lecturing publicly on mathematics, astronomy, and philosophy to students who came from across the Mediterranean to hear her. She edited and preserved the works of earlier mathematicians, refined astronomical instruments, and was admired even by those who disagreed with her for the clarity and dignity of her teaching.

She lived at a moment when her cosmopolitan city was tearing along its religious and political seams, and she would not bend to any faction. Pagan by philosophy, she counted Christians among her devoted students and advised the civic leaders of Alexandria. That independence made her a target. In 415, caught in the violence of the city's feuds, she was seized by a mob and brutally killed — a scholar murdered for her learning and her refusal to take a side.

Her death came to stand for the fragility of reason in an age of fanaticism, and her life for its quiet courage. We honor her as one of the first women in the recorded history of mathematics — the teacher who stood before the world and insisted, against the gathering dark, that the mind is free.
