  • Named for Charles Julien Brianchon (1783-1864), a French mathematician and chemist. Brianchon is best known for his proof of Brianchon's theorem (1810).
  • This feature was Catalog Numbers 1360 and 1695 in Mary Blagg's Collated List (1913), where it is said to have been called Anaximander C in Neison, 1876 and Anaximenes C in Beer and Mädler. It entered the original IAU nomenclature of Named Lunar Formations (1935) as Carpenter C (Catalog Numbers 1695). A note there mentions the same feature was labeled by Franz as Anaximander d.
  • The replacement name Brianchon was given by Arthur and Whitaker in the Rectified Lunar Atlas (1963) and approved by IAU in 1964.
  • A pronounced valley between Brianchon and Sylvester (north of Brianchon, east of Froelich) is unofficially called Vallis Sylvester by D. Caes. See LAC 9 in the Clementine Atlas (the upper right corner of LAC 9). Note that this valley is NOT Catena Sylvester!
  • A very narrow valley running through Brianchon A at the northern part of Brianchon's rim is unofficially called Vallis Brianchon A by D.Caes
