Truman Safford discovered NGC 237 = Sf 94 on 27 Sep 1867 with the 18.5" refractor at the Dearborn Observatory. His discovery list was not published until 1887, so Dreyer was unable to credit him in the NGC. The galaxy was independently found by Lewis Swift on 21 Nov 1886 with a 16" refractor at Warner Observatory and catalogued it as #6 in his 6th discovery list, though his position was 16 seconds off in RA. Swift is credited with the discovery in the NGC. Herbert Howe measured an accurate position in 1897 using the 20" refractor at the Chamberlin Observatory in Denver.
300/350mm - 13.1" (12/7/85): fairly faint, fairly small, almost round, weak concentration.
400/500mm - 17.5" (10/8/88): fairly faint, fairly small, elongated NNW-SSE, brighter core.
