William Herschel discovered NGC 3737 = H III-772 on 14 Apr 1789 (sweep 920) and recorded "vF, stellar neb." His position is accurate (discovered immediately after NGC 3733). d'Arrest also measured two accurate positions.

400/500mm - 17.5" (3/19/88): fairly faint, very small, round. Forms a pair with CGCG 268-057 = NGC 3737A 1.3' SW. The companion appeared extremely faint, very small, slightly elongated. Member of AGC 1318.
