Henri de Toulouse-Lautrec was a human painter.
Following a trail through time, using a bag of items left for the Doctor by the Demon, one of which was a poster by Lautrec edited to feature the Doctor's face, the Fourth Doctor and Fenella Wibbsey encountered Lautrec in 1890s Paris. Lautrec was rumoured to be murdering young women, as prostitutes and dancers were going missing. However, it transpired that it was in fact the Demon, disguised as La Concierge, who needed to feed off the life force of the girls. (AUDIO: The Demon of Paris)
An android copy of him was in the Paloma Centre. The Eleventh Doctor used his sonic screwdriver to control it into attacking the invading Arucha. (PROSE: The War of Art)
