Named after Gabriel Lamé - French mathematician (1795-1870).
Lamé is a lunar impact crater located astride the northeast rim of the crater Langrenus, to the east of Mare Fecunditatis. The eastern crater rim appears overlaid by a series of overlapping craters that form an intermittent chain flowing nearly a hundred kilometers to the south. The crater rim protrudes only slightly above the surrounding terrain, but it has a significant rampart where the rim lies within Vendelinus. In the middle of the floor is a slight ridge, forming a central peak. (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.
