Humbolt
Chief Humbolt was a Human male Starfleet crewman who lived during the mid-23rd century. He served in the sciences division at Starbase 11 in 2267 under the command of Commodore José I. Mendez. He was one of the technicians assigned to the base's computer center. 

That same year, Humbolt had the task of identifying the source of a mysterious transmission ostensibly sent from the base, diverting the  from its regular patrol route. 

Later, Humbolt discovered the Enterprises first officer, Lieutenant Commander Spock, attempting to forge a transmission from Captain James T. Kirk, placing Spock in command. Humbolt attempted to forcibly subdue Spock, but was incapacitated by a Vulcan nerve pinch. ()
