Ensign Mayer was a Starfleet officer assigned to the USS Enterprise-E in the 2370s.
In 2375, he was part of the Enterprise contingent on Deep Space 9 that treated the Vulcans of the Damask Plain. He was in such a hurry to help one patient that he lost his boot and didn't realize it until he broke his foot running into a console. (DS9 short story: "Mirror Eyes")
