Palomar 13 was discovered by A.G. Wilson (1955) and named by him the Pegasus Globular Cluster, together with globular clusters Palomar 3, Palomar 4 and Palomar 5, and two new Local Group galaxies. That naming was certainly not essentially a happy choice, as Pegasus also contains the prominent globular M15. G.O. Abell (1955) cataloged them with their Palomar numbers.
