Named after Bertil Lindblad - Swedish astronomer (1895-1965).
Lindblad is an old lunar crater on the far side , just beyond the northwestern limb. This formation is located to the southeast of the crater Brianchon, and northeast of Cremona. The fine detail along the rim of this crater has been worn down by a history of lesser impacts, leaving only a round-edged depression in the surface. The more recent impact Lindblad F intrudes slightly into the eastern rim, and several tiny craters lie along the northwern and southwest rim. (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.
