Elizabeth Rogers played Lieutenant Palmer, a relief communications officer aboard the Enterprise, in two episodes and supplied the voice of the Companion in Metamorphosis.
Elizabeth Rogers (1934–2004) contributed to three episodes of The Original Series.
Her first job was heard rather than seen: in Metamorphosis she provided the gentle voice of the Companion as rendered through the universal translator, in the scenes where Kirk tries to persuade the cloud creature to release Zefram Cochrane.
Shortly afterwards she was cast as Lieutenant Palmer, who takes the communications station in The Doomsday Machine, an episode made while Nichelle Nichols was unavailable. Palmer relays the garbled distress call from the Constellation and handles ship-to-ship signals during the battle with the planet killer. Rogers repeated the role in the third season in The Way to Eden.
