Meg Wyllie

Actor (The Keeper) — The Original Series

American actress (1917–2002) who played the Keeper, leader of the Talosians, in the first Star Trek pilot The Cage and in The Menagerie.

Meg Wyllie was an American character actress, born in 1917, with a long career in television; her later film work included Granny Gordon in The Last Starfighter (1984).
In The Cage she played the Talosian magistrate known as the Keeper, who holds Captain Pike in the menagerie and attempts to breed a race of human servants. The producers cast women as the Talosians and dubbed them with men's voices to make the aliens seem strange; the Keeper's voice was supplied by Malachi Throne, and was altered for The Menagerie because Throne also appeared on screen in that story as Commodore Mendez.
Wyllie died in 2002.
