Ken Lynch played Vanderberg, the hard-pressed chief engineer of the pergium mining colony on Janus VI, in the first-season episode The Devil in the Dark.
Ken Lynch (1910–1990) was a gruff-voiced American character actor who played policemen and officials in a great many films and television series.
In The Devil in the Dark he is Chief Engineer Vanderberg, the administrator of the Janus VI mining station, who summons the Enterprise after some fifty of his men have been killed by an unseen creature. He is impatient with Spock's scientific curiosity and wants the thing destroyed.
When the Horta is cornered, Vanderberg leads his armed miners into the chamber, only to learn that the silicon nodules they have been smashing were its eggs. He accepts Kirk's proposal of a partnership, and ends the episode cheerfully reporting rich new finds tunnelled by the hatchlings.
