Arnold Schwassmann found IC 3427 = Sn. 158 on 6 Sep 1900 using a plate taken with a 6" astrograph at Heidelberg, and later by Frost at Harvard in 1904. William Herschel made the original discovery on 15 Mar 1784 (sweep 174) but his position for H III-40 (later NGC 4482) was poor (28 sec of RA too far east and 2' too far south) and Dreyer assumed Schwassman's and Frost's object was different than NGC 4482. So NGC 4482 = IC 3427. UGC, MCG and CGCG label this galaxy IC 3427, instead of NGC 4482.

400/500mm - 17.5" (4/21/90): faint, fairly small, oval 3:2 NW-SE, almost even surface brightness.
