Khan (Earthshock). The Mongol title for people like Kublai Khan's probably the more likely "primary topic" for the undisambiguated name.
Talk about it here.
Dr Khan was the assistant of Professor Kyle.
Dr Khan was a member of an expedition exploring a recently discovered cavern rich in fossils somewhere on Earth. Khan was killed along with six others by the Cybermen's androids due to their close proximity to the Cyber-bomb's hatch. Khan's coat and a small pick hammer that belonged to Khan were found by Kyle just after she and Lieutenant Scott discovered the Fifth Doctor and his companions. (TV: Earthshock)
