Named for Jean-Baptiste Chappe d'Auteroche (1728-1769); French astronomer.
This name was proposed to the IAU by amateurs as part of their Luna Incognita project to fill in areas left blank on the Lunar Orbiter maps. It was approved in 1994 (IAU Transactions XXIIB).
Although listed in the IAU Planetary Gazetteer as replacing the former lettered crater designation Hausen A, that name appears to have been part of Ewen Whitaker's effort to letter the farside for NASA RP-1097 (1982) and was never approved by the IAU.
