Arthur Candy

Professor Candy, who signed his name as Arthur Candy while stuck in 1996 Birmingham (PROSE: Afterwords) but whose business card in his native time read Artrem Candy (GAME: The Eternity Clock) was a history researcher on the faculty of Luna University's archaeology department. Much of his research centred on the Doctor.

History
In 2593, Professor Candy accompanied Bernice Summerfield to a dig on Perfecton, where he experienced the attack of the Grel. After a Perfecton hit their spaceship Winton, he found himself in Pantoland in the persona of Dame Candy. She delighted in creating puns on what she saw, such as using fish related dialogue when she met the Grel. She was the mother of Young Jack from the village. (AUDIO: Oh No It Isn't)

Studying the Doctor's place human history, Candy concluded that the Doctor had a generally negative and dangerous effect on history. His attempt to give a lecture to this effect in 2643 was pre-empted by the Doctor, (PROSE: Continuity Errors) who carried him back in time and left him in Birmingham in 1996. (PROSE: Afterword)
