- Named for Albert Graham Ingalls (1888-1958), described by the IAU as an "American optician." He is best remembered for hosting the "The Back Yard Astronomer"/"Amateur Scientist" feature in Scientific American from 1928-1955, and for editing the related three-volume Amateur Telescope Making book series.
- A crater at (or near) the IAU's Ingalls seems to have been called Morehouse (N° 536) on the Shternberg Astronomy Institute's Second Complete Moon Map - 1969. Research: Danny Caes.
- Ingalls was once H.P.Wilkins's name for Riccioli C.
- What appears to be an officially unnamed chaotic-looking large depression southwest of Ingalls (east of Mineur) looks like a smooth-floored unit on Hans Schwarzenbach's Hallwag-map of the moon's far side. - DannyCaes Feb 12, 2012
