William Herschel discovered NGC 1332 = H I-60 on 9 Dec 1784 (sweep 331) and logged "vB, S, lE, mbM." On 19 Dec 1799 (sweep 1091) he recorded "Two [along with NGC 1331], the 1st [NGC 1332] vB, SBNcl with faint branches from np to sf." The position of NGC 1331 is too far west in the NGC, so the pair is out of RA order.

Joseph Turner sketched the pair on 26 Nov 1875 with the Great Melbourne Telescope (unpublished plate II, figure 9) as well as Pietro Baracchi on 7 Jan 1885.

200/250mm - 8" (12/6/80): fairly bright, fairly small, elongated NW-SE, bright core, diffuse halo. NGC 1331 not seen.

300/350mm - 13.1" (10/10/86): bright, moderately large, very bright core, edge-on 4:1 NW-SE, 2.4'x0.6'. A faint mag 14-14.5 star is just southwest of the core. Forms a pair with NGC 1331 = IC 324 2.8' SE (collinear with the major axis). NGC 1332 is the brightest in a group with NGC 1315, NGC 1319, NGC 1325, NGC 1331 and Holmberg VI NGC 1325A).
