Weston (The Only Good Dalek)

Professor Weston was a scientist who had worked on Station 7, in order to use the Daleks' own technology against them, with assistance from Hadleigh and Kustler. His main project was the creation of a pacified Dalek through genetic modification. When he presented the findings, he was met with resistance, voiced among others by a young Tranter. In order to continue his research, he detached his lab from the rest of Station 7 and let it crash on the planet below the station. Using the planet's abundance of lava and ice, he constructed steam-powered machinery to work with, undetectable by the Daleks. Other known work included enhancing some of the planet's native inhabitants, repairing his own broken body, and the creation of the one pacified Dalek which valued life and was grateful to Weston.

Some years later he was found by the Doctor and Tranter, soon followed by Jay and Amy Pond, and the Daleks. Soon afterwards, he was taken prisoner by the Daleks and sacrificed himself in order to let the Doctor and the others escape. He left his research on a computer disc he gave to Jay to give to Earth, hoping it could turn the tide of the war. (GN: The Only Good Dalek)
