Named after Georg Békésy - Hungarian otological physicist; Nobel laureate (1899-1972).
Von Békésy is a worn lunar crater on the far side. It is located in the northern latitudes, behind the northeastern limb as seen from the Earth. This is a isolated crater formation, the closest named crater being Volterra, just over one crater diameter to the north-northeast. To the southwest lies Millikan. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
