Professor Quandry was a "vexatious" Victorian academic to whom Rupert Von Thal was an assistant. He attended the Block Transfer Computation "séance" that the Fifth Doctor had arranged in Beatrice Mapp's large Bloomsbury home, sitting besides Brenda. He assumed that Nyssa was Mapp's maid and scolded her for telling him to have patience while waiting for the séance to start. Once the séance began, Quandry repeated the numbers "1110". (AUDIO: The Boy That Time Forgot)

Behind the scenes Edit

Alternative versions of Mapp and Von Thal appear in the Brenda and Effie novel The Bride That Time Forgot, alongside a "Quandry" who is revealed to be a false identity used by Professor Cleavis, who travelled to the 19th century on a mission from MIAOW using the Blithe Pinking Shears.
