His name is Professor A.A. Dinwiddie, DM (7th), D.Thau., B.Occ., M.Coll., but, like most of the faculty, he is generally referred to by his title.
The Bursar is a quiet, reserved person, who took the job of University treasurer because he had an affinity for numbers.
The brashness of Ridcully's personality wore away at the Bursar, a man whose idea of excitement was a soft-boiled egg, and Dr. Dinwiddie is now almost completely insane. He is kept functional, just, by experimental dosages of dried frog pills, though the effect is sometimes erratic. The pills are actually hallucinogens, the idea being that a proper dosage will cause him to hallucinate he is sane.
