The chief in charge of the computer centre at Starbase 11 in 2267, who caught Spock tampering with the equipment and was subdued with a Vulcan nerve pinch.
Chief Humboldt appears in The Menagerie, Part I. He is responsible for the starbase computer room that Spock enters in secret to fabricate orders sending the Enterprise away with Christopher Pike aboard.
Humboldt walks in to find the Vulcan working inside an open panel, feeding recorded snippets of Kirk's voice into the system. He challenges him, saying that no one has been cleared to use the room, and tries to pull him away.
After a short scuffle Spock renders him unconscious with a nerve pinch and finishes the job, transmitting the faked instructions to the ship. Humboldt's part is brief, but it is the first open sign that Spock is committing mutiny. He was played by George Sawaya.
