Guyot and Guiot
Probably not at all related to Arnold Henry Guyot, but... it might be interesting to try to search the biography of a certain Guiot who observed planet Mercury at Soissons through a 3-3/4 inch refractor, see footnote at page 58 in the chapter MERCURY in T.W.Webb's Celestial Objects for Common Telescopes, Volume 1: The Solar System (Dover, 1962). - DannyCaes Jul 15, 2015
