Gachet

Dr Gachet was one of Vincent van Gogh's doctors.

Biography
In 1890, Gachet was looking after Vincent, who was screaming after painting The Pandorica Opens. After painting it, Vincent went mad, possibly due to him believing that Amy Pond and the Eleventh Doctor would die. (TV: The Pandorica Opens)

While under his care, Vincent painted a portrait of Gachet. It was eventually added to the collection of van Gogh's paintings in the Musée d'Orsay. (TV: Vincent and the Doctor)
