According to the Interwebs: In 1596, or there about, a Sir John Harrison, one of the many godson's of the Queen of England, created the private toilet for the Queens pleasure. Many people made improvements to the toilets design but it was always referred to as the "John." :)
@beautifulthing Why thank you! Mystery solved! :) I figured it was something historical (everything always is), but I was too lazy to use the interwebs :)
