William Herschel discovered NGC 4464 = H III-483 = h1292 on 28 Dec 1785 (sweep 498) and simply noted "vF". JH made the single observation "pB; vS; pgbM; R; 10"." Julius Schmidt found the galaxy again in June 1861, along with NGC 4470 and 4492, and reported them as new in AN 1513 (1866), although Heinrich d'Arrest quickly reported the earlier discoveries. d'Arrest also measured the position accurately on 4 nights.

400/500mm - 17.5" (4/18/87): moderately bright but very small, irregularly round, high surface brightness, small bright core, possible stellar nucleus. M49 is at the edge of the 220x field 11.5' SE.
