Murray Stevens

Murray Stevens was an Australian scientist and assistant to Rudolph Steiner on the Gemini Plan. He calculated that the plan to move Venus in Earth's orbit would lead to the destruction of Earth, but Steiner refused to listen. Stevens sabotaged the computer room and fled, meeting up with the Doctor along the way. After a meeting with a group of Aborigines, Stevens helped the Doctor stop the project and alerted UNIT to the goings-on. (TVA: Gemini Plan)

Murray Stevens was given the name Murray Lever twice in the text.
