The Necessary (a.k.a. the outhouse)
The necessary (a.k.a. outhouse) had many Victorian Era-appropriate euphemisms: Quincy, small room, washroom…and was replaced with modern indoor plumbing both very early (1820’s at the White House) and very late (1950’s) in rural America. What did homeowners do when the necessary filled up? (ewww!) When was toilet paper invented? Why did outhouses have more than one seat?
