Wilhelm Tempel discovered NGC 4757, along with NGC 4766, in 1882. In the narrative portion of his fifth paper (AN 2439) he mentions finding two nebulae about 10' north of Winnecke's GC 5674 [NGC 4760]. Although no positions are given here, they were probably measured and communicated later to Dreyer, as the NGC position is 1.6' south of MCG -02-33-040 = PGC 43715. This galaxy lies 12' north-northwest of[NGC 4760.

400/500mm - 17.5" (5/17/90): faint, small, round. An extremely faint star is at the NW edge. Forms a pair with NGC 4766 5' SE.
