In culture
The protagonist of the novel Wetlands, and the film based on the book, would be considered a mysophiliac, deriving pleasure from not washing and from dirty locations, such as toilets.
Napoleon Bonaparte, while campaigning in 1796, wrote to his wife Joséphine: "Please don't wash, will arrive in three days".<ref>Template:Cite web</ref> This can be interpreted as mysophiliac behaviour if it is assumed this was to ensure her clothes, as well as her person, were soiled.
