Description
Stepped on by Wargentin and Phocylides, Nasmyth has lost about 1/3 of its original existence. It has a battered rim and a smooth floor. Although Nasmyth was a great engineer and 19th century contributor to studies of the Moon, he deserved a better crater and this should have stayed Phocylides B.

Several observers of the Phocylides/ Nasmyth/ Wargentin sector seem to have noticed some sort of temporary "absence" of Nasmyth A, the small crater on the floor of Nasmyth itself. See pages 160 and 161 of Harold Hill's A Portfolio of Lunar Drawings.- DannyCaes Jul 27, 2012
Nomenclature
- Named for James Hall Nasmyth (August 19, 1808 – May 7, 1890), a Scottish engineer and inventor famous for his development of the steam hammer. He built his own 20-inch reflecting telescope and made detailed observations of the Moon. He co-wrote The Moon : Considered as a Planet, a World, and a Satellite with James Carpenter (1840–1899). This book contains an interesting series of "lunar" photographs: because photography was not yet advanced enough to take actual pictures of the Moon, Nasmyth built plaster models based on his visual observations of the Moon and then photographed the models.
- According to Mary Blagg's Collated List (1913), this feature (catalog number 2274) was known to her three authorities as Phocylides b. The modern name, approved by IAU in Named Lunar Formations (1935), comes from a map published in 1887 by Gaudibert and Fenet (Whitaker, p. 150).
- Erroneously printed as Nasymth on page 76 (libration chart 5) in the 21st Century Atlas of the Moon (2012).- DannyCaes Jan 23, 2013
