David Todd discovered NGC 4063 = Todd 12b on 2 Jan 1878 during his search of a trans-Neptunian planet using the 26-inch Clark refractor at the USNO. Édouard Stephan found the galaxy again on 3 May 1881 and reported the discovery in list XI-15. Stephan's position is accurate (he mentioned it was distinct from [N4073] and [N4077]) and Dreyer credited him with the discovery in the NGC.

400/500mm - 17.5" (5/10/86): very faint, very small, slightly elongated N-S. In a group with UGC 7042 3.9' NW, NGC 4073 6.0' ENE and NGC 4139 7.5' SE.
