Named after Immanuel Kant - German philosopher (1724-1804).
Kant is a small lunar impact crater that is located to the northwest of the prominent crater Cyrillus and the comparably sized Ibn Rushd. To the northwest is Zöllner, and to the east is Mons Penck. This last feature forms a mountainous promontory reaching a height of about 4 km. This crater has a well-defined and somewhat uneven rim that is roughly circular in shape. (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.
