William Exeter was a psychologist from New York University.

In 2362, he took part in an educational stellarcast on the 100th anniversary of the Interstellar Alliance alongside historian Dr. Jim Latimere from the University of York and political scientist Dr. Barbara Tashaki, University of Japan at Tokyo, discussing the actions and character of John Sheridan. Like Dr. Tashaki, he was a fierce critic of Sheridan.[1]
