Euclides D

(current and past IAU name; also briefly known as Eppinger, a disallowed IAU name)

Lat: 9.4°S, Long: 25.7°W, Diam: 6 km, Depth: km, Rükl: 42

LO-IV-132H The dark band across the top of the frame was a flaw in the original on-board development of the Lunar Orbiter film.

From the shadows in LO-IV-132H, Euclides D is 1200-1250 m deep. LO-IV-125H gives a depth of about 1120 m, probably because the shadows are not reaching the deepest part of the floor. - Jim Mosher

The name Euclides D was part of the original IAU nomenclature of Blagg and Müller (1935).
The IAU's newly-formed WGPSN proposed approving the replacement of Euclides D with the name Eppinger, after Czechoslovakian doctor Hans Eppinger (1879-1946) as it had been provisionally assigned on LTO 76D1, and for which it served as the chart name. The change was adopted by the General Assembly in 1976 (IAU Transactions XVIB).
Subsequently it was brought to the attention of the WGPSN that Eppinger had participated in medical experiments in the Nazi death camps during World War II. As a result the use of Eppinger's name in connection with this crater was officially disallowed in October 2002 (IAU Transactions XXVA).
In 2006, the IAU Planetary Gazetteer added the list of lunar satellite features from 1982's NASA RP-1097 (IAU Transactions XXVI). Unfortunately, Blagg and Müller's Euclides D was listed there as Eppinger, so the old IAU name was not re-instated at that time.
The crater briefly known as Eppinger was officially reinstated as Euclides D by the IAU in July 2009.
