It was first discovered by Danish astronomer John Dreyer on 26 April 1878, and he described it as a "faint object, very small and with a much brighter middle." He also described it in his notes on the accompanying galaxy, PGC 37703, which he described as "a tail north of the nucleus".[2]
Together, NGC 4015 and PGC 37703 comprise Arp 138 in the Atlas of Peculiar Galaxies.
