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
