Lovelace is a lunar impact crater on the far side , just behind the northern limb. It lies to the south-southwest of the crater Hermite, and just to the north of the slightly smaller Froelich. To the east is Sylvester. The outer wall of this crater is nearly circular, with a well-delineated rim that is not significantly worn. (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.
