This galaxy is a member of the Virgo Cluster.
Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "B vmE vBM 9 or 10' long."

(Sulentic and Tifft 1973) notes that this is a 11.0 mag galaxy. Their coded description reads ALMEON,BM,B,DKLNS.
This galaxy appears on page 25 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).

Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10.9M; 7.2' x 1' extent; faint, bright, spindle shaped glow with axis oriented N-S; see photo at HAG-25; extremely faint SP GAL N4206 (13M; 3' x 0.5' extent) 10' to SW!; both are good supernova prospects."
Coe, observing with a 13" f/5.6, notes: "pretty bright, large, much elongated with a very bright middle at 100X. The fascinating thing about this object is that it is within a 30' field of two other edge on galaxies. The northernmost is extremely faint, pretty small, very much elongated and not brighter in the middle. The southernmost is faint, pretty small, much elongated and somewhat brighter in the middle. With 4216 in the center of this array of spindle shaped galaxies, this is a spot that fascinated me."
Observing site: Pinnacles overlook
Telescope: C-8
[12h 15m 54s, 13° 9m 0s] A lovely, diaphanous, faint streak of light with a bright, almost stellar nucleus.
Location: Sutton, Pembs UK.
Time: 01:50
Telescope: 200mm F5 EQ Newt.
Limiting magnitude:6
Sky conditions:7/10
Bright, easy to see, full size visible at 50X with a stellar core like a mag 12 star. Also NGC 4026, another edge on spiral about 10' to the SW was clearly seen though fainter.
4216 is an excellent example of an edge on Galaxy galaxy, well worth seeing.
