Major Baker was a former British military officer who served as security officer of the Wenley Moor research centre during the early 1970s. He was captured by the Silurians, who infected him with a virus, after which they let Baker go. Baker went to the research centre, but collapsed and was taken to a nearby hospital by Dr. Meredith. He later died from the virus. (DW: "Doctor Who and the Silurians")
