Lieutenant Lindstrom was a male Human Starfleet officer in the 23rd century. He served as a sociologist in the sciences division aboard the USS Enterprise in 2267 under the command of Captain James T. Kirk, during the historic five-year mission.
That same year, the Enterprise visited planet Beta III, searching for clues to the fate of the Archon, lost there a century earlier. Lindstrom's initial error in attire led to the quick identification and absorption of the first landing party, Lieutenants Sulu and O'Neil. Kirk then put together a six-man landing party that included Lindstrom. Subsequent events revealed the fate of the Archon, and left Beta III without effective governance; Lindstrom and other experts remained behind to help guide the culture back to a more Human form.
