Although there are records of latrines dating back to 3100 BCE, the first flush toilet was invented in 1596 by Englishman John Harington. He produced two units: one for himself and another for Queen Elizabeth I.
The idea did not catch on at the time, and it was only in 1775 that Scotsman Alexander Cumming patented the modern toilet, designed to connect to a sewage system. In 1885, another Englishman, Thomas Twyford, created the first porcelain toilet, replacing the wooden models that preceded it.
