Charles Lawrence

Dr Charles Lawrence was the director of the Wenley Moor nuclear research facility. He refused to cooperate with UNIT's investigations, as he felt their investigations were frivolous and unproductive in solving his power loss problem; he eventually called in his friend Masters in an effort to have UNIT removed. His disbelief in the existence of the Silurians and distress over the plant's apparent shut down eventually led to his death, as he refused to be inoculated against the Silurian virus, which he succumbed to. (TV: Doctor Who and the Silurians)

He died at 4pm on 21 November. He had received a letter from the Apocalypse Clock which predicted the exact date and time of his death. (AUDIO: The Last Post)

Behind the scenes
In Doctor Who and the Cave-Monsters, the novelisation of Doctor Who and the Silurians, Dr Lawrence was killed in the facility's cyclotron room by the Silurian Morka's third eye.
