Sherburne Wesley Burnham discovered IC 113, along with IC 115, on 25 Jul 1890 with the 36-inch refractor at Lick Observatory. He noted "vF, 3' nf of * 5m [Rho Psc]" and measured an accurate positon based on the bright star.

600/800mm - 24" (10/1/16): at 375x; very faint to faint, small, round, 15" diameter, low surface brightness. Situated 2.7' NE of mag 5.4 Rho Psc and 5' SW of mag 5.5 94 Psc! These stars are very bright and very distracting if within the field! It was easy to place 94 Psc outside the edge of the field and with a little care Rho Psc could also be moved just outside the edge of the 10mm Zeiss Abbe Ortho. IC 115 lies 7' ENE. Located at a redshift-based light travel time of ~585 million years in the cluster AGC 195.
