Cunningham
Cunningham was an operations division crewman third class aboard the Earth starship Enterprise, where he worked in the galley.
In 2152, he was affected by radiation from a singularity that caused excessive and obsessive behavior. (ENT: "Singularity")
Later that year, his body was also taken over by non-corporeal beings who had abandoned their damaged ship and needed hosts to survive. He took refuge in the catwalk. While there, Cunningham asked Travis Mayweather how long he thought they would be in the Catwalk, and later pointed out to Mayweather where he thought Charles Tucker might be. (ENT: "The Crossing")
In 2153, when Captain Jonathan Archer was looking over the plates displayed in the Enterprise mess hall, T'Pol told him that Cunningham was in the galley if he wanted something else. (ENT: "Regeneration")
