Herbert Howe discovered IC 4329 = Ho. III-20 on 21 Jun 1900 with the 20-inch Clark refractor at Chamberlin Observatory in Colorado. He noted "F, cS, bM" and measured an accurate position, though he missed IC 4329A.

400/500mm - 17.5" (3/12/88): fairly faint, fairly small, oval WSW-ENE, bright core, stellar nucleus. Forms a pair with IC 4329A 3' E. This galaxy is the brightest in the IC 4329 cluster (AGC 3574).
