Hilda Hutchens
Dame Hilda Hutchens was an Oxford professor of philosophy.
She published Empirical Epistemology whilst she was a young don. She later wrote Quantum Qualia and The Emptiness of the Busy Mind, the latter of which she admitted was a rather pop title. In 1970, she won the Nobel Prize for Philosophy. She and the Third Doctor knew each other and had what Hutchens called "delicious arguments".
She joined the Skangite cult to the astonishment of many of her colleagues, and wrote The Way of the Skang as Mother Hilda. She became part of their inner council. Eventually she was taken over by the Skang parasite within her. When the Third Doctor put the individual elements of the Skang into time loops, what remained of Hutchens turned into dust.
