Professor Chronotis
Professor Urban Chronotis is a fictional character created by Douglas Adams. He was originally created for the 1979 Doctor Who serial Shada, starring Tom Baker and Lalla Ward. However, the filming of the serial was never completed due to a strike. Adams then re-used the character and many of the themes from Shada in his novel Dirk Gently's Holistic Detective Agency, first published in 1987. In both versions, Chronotis is a clandestine time-traveller, whose time machine (or TARDIS, as they are termed in Doctor Who) is disguised as his college rooms.read more
