Boltzmann

Lat: 74.9°S, Long: 90.7°W, Diam: 76 km, Depth: km, Rükl: (farside)

Named for Ludwig Eduard Boltzmann (1844-1906), an Austrian physicist.
This name was assigned in the [/Rectified%20Lunar%20Atlas Rectified Lunar Atlas] (1963), based on Earth-based photos of the [/librations libration] zones, and approved by the [/IAU IAU] in 1964, to which it was described as a 70 km diameter crater at 75.5°S, 96.0°W.
In preparing its initial long list of farside names, the IAU Working Group for Lunar Nomenclature was initially unable to find evidence in space-based overhead views of a significant crater at that location, and announced at the August 1970 meeting its plan of deleting the 1964 approval and reassigning the name to the larger nearby crater now known as [/Lippmann Lippmann].
Subsequent to the 1970 meeting, Whitaker produced space-based images of the crater he had intended to name. The name was reapproved in Menzel, 1971 as representing the crater at 75°S, 90°W.
The version of [/DMA ACIC] map [/LMP LMP-3] from October, 1970 (prepared before the final IAU farside list had been published) labels Boltzmann at the proposed changed location.
