William Herschel discovered NGC 4065 = H III-395 on 18 Mar 1865 (sweep 403) and recorded "Six nebulae. The places belong to the three first [III-391, III-392 and III-393]..." The three galaxies to the south, which he did not measure positions, are likely NGC 4061, NGC 4065, and NGC 4076 (the three brightest). John Herschel recorded this nebula twice as h1067 and noted "pB" on one sweep and "vF; R; the second of 5" on another. His position on sweep 409 is at the southeast edge of the halo.

NGC 4057 = h1063, recorded on 29 Apr 1832 (the same night he logged h1062 = NGC 4055 and h1064 = NGC 4059), is very likely a duplicate observation. See notes for that number.

400/500mm - 17.5" (3/28/87): fairly faint, small, slightly elongated, brighter core. Brightest in the NGC 4065 cluster (a large group of NGC galaxies) with NGC 4061 1.1' WSW.

600/800mm - 24" (3/22/14): moderately bright, fairly small, round, 30" diameter, well concentrated with a small bright core. Forms a close pair with NGC 4061 just 1' W. NGC 4072 lies 2.4' SE and NGC 4076 is 6.5' ESE. NGC 4066 and 4070, two similar ellipticals, lie 6.8' N and 10.5' N.
