Named after Hypatia of Alexandria - Egyptian mathematician and philosopher (c. 370-415).
Hypatia is a lunar crater that lies along the northwest edge of Sinus Asperitatis, a bay on the southwest edge of Mare Tranquillitatis. The nearest crater with an eponym is Alfraganus to the west-southwest. However, farther to the south-southeast, across the lunar mare, is the prominent crater Theophilus. Hypatia is an asymmetrical formation with a rugged, irregular outer rim that is cut through by narrow clefts in several locations. (wikipedia entry)
