Named after George Bergh - Dutch astronomer (1890-1966).
Van den Bergh is an eroded lunar crater on the far side. It lies just to the east of the larger crater Cockcroft. To the north is Evershed. Since its formation, this crater has been heavily worn by subsequent impacts until its features have become softened and rounded. (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.
