Chief Scientist (The Secret of the Emperor)

Chief Scientist was leader of the Dalek Scientific Division that was part of the Kar-Charrat mission to obtain information from the planet's library in the 42nd century. They were sent on that mission by the Dalek Supreme, the immediate subordinate of the Emperor. The Chief Scientist and other Scientist Daleks created the first Dalek test subject. The first one went mad. The second test subject obtained the information, but it disobeyed the Dalek Supreme's orders. The Emperor placed the Chief Scientist in command of the Dalek Supreme's mothership. (AUDIO: The Genocide Machine)
