Named after Ernest Amedee Barthelemy Mouchez - French astronomer (1821-1892).
Mouchez is the remnant of a lunar crater that is located near the northern limb , to the north of Philolaus and northwest of Anaxagoras. Almost the entire eastern rim of this crater is missing, and the remaining arc is heavily worn and eroded. This surviving rim forms a curving arc that runs from the south clockwise to the north-northeast. (wikipedia entry)
