Sturgeon was a male Human Starfleet enlisted crewmember who lived during the mid-23rd century. He served in the sciences division aboard the USS Enterprise under the command of Captain James T. Kirk, during the historic five-year mission.
In 2266, Sturgeon, along with Crewman Green, both armed with a type 2 phaser, made up the two-thirds of the landing party that joined Captain Kirk to the surface of planet M-113 to investigate the death of Darnell, a crewman who had apparently been murdered during the visit of the previous visit to the surface. Kirk ordered Sturgeon to locate and collect a sample of the poisonous Borgia plant, which was supposedly the cause of Darnell's death. While searching, however, Sturgeon was attacked and killed by a creature which extracted all of the salt from his body as a form of sustenance. (TOS: "The Man Trap")
