Nomenclature
- The name of this crater honors two men:
- James Carpenter (1840-1899), a British astronomer
- Edwin Francis Carpenter (1898-1963), an American astronomer.
- According to Mary Blagg's Collated List (1913), this crater was known to her three authorities as Anaximander b (catalog number 1692). The modern name that was adopted by the IAU in its original Named Lunar Formations (1935 -- apparently honoring James Carpenter), was introduced on a lunar map published by Gaudibert and Fenet in 1887 (Whitaker, p. 150). - JimMosher
- E. F. Carpenter was added as a second honoree in 1985 (IAU Transactions XIXB). (He was professor of Astronomy at Univ of Az when I became an undergraduate there - he allowed me to use the small telescopes for observing!) - tychocrater Sep 13, 2009
- Maybe we could add Malcolm Scott Carpenter too (1925-2013); American test pilot, astronaut, and aquanaut. Second American in orbit around earth, after John Glenn. - DannyCaes Oct 25, 2014
