This was probably the first globular cluster discovered, by Abraham Ihle in 1665. According to Kenneth Glyn Jones, it is supposed (e.g. by Admiral Smyth) that Hevelius may have seen it even earlier, but Halley, De Chéseaux and Messier commonly acknowledge Ihle's original discovery. This globular was included in Halley's list of 6 objects published 1715, and observed by De Chéseaux (his No. 17) and Le Gentil as well as by Abbe Nicholas Louis de la Caille, who included it in his catalog of southern objects as Lacaille I.12. Charles Messier, who cataloged M22 on June 5, 1764, states that it is also included in John Bevis' English Atlas.
