Discovered by James Dunlop on July 28, 1826.

James Dunlop discovered this globular cluster on July 28, 1826 and cataloged it as Dunlop 295.

Owen Gingerich (1960) has suspected that this cluster may have been discovered previously by Abbe Lacaille in 1751-52, but measured at a position more than 10 degrees off, and cataloged as Lac I.13. Lacaille's presumably invalid object position has found its way into John Herschel's GC of 1864 as GC 4484, and J.L.E. Dreyer's NGC as NGC 6777.

    In 1995, NGC 6752 was investigated in the Ultraviolet by the Ultraviolet Imaging Telescope (UIT) on its Astro-2 Space Shuttle mission (STS-67, Endeavour orbiter). Results highlight evolved stars in the cluster, in particular the so-called horizontal-branch [blue-white] giants.
