With the population explosion of the last century, major changes in sewage removal and sanitation were necessary. Two men offered important designs for the modern flush toilet. Sir John Harington was a poet in 16th Century England, while Thomas Crapper was a plumber and businessman in the same country 300 years later. Harington will be remembered for eloquent words about the toilet and Crapper may be assured even greater remembrance for selling toilets and being named Crapper.
