Alexander Cumming
Alexander Cumming FRSE (sometimes referred to as Alexander Cummings; 1733 – 8 March 1814) was a Scottish watchmaker and instrument inventor, who was the first to patent a design of the flush toilet in 1775, which had been pioneered by Sir John Harington, but without solving the problem of foul smells. As well as improving the flush mechanism, Cummings included an S-trap (or bend) to retain water permanently within the waste pipe, thus preventing sewer gases from entering buildings. Most modern flush toilets still include a similar trap. Provided by Wikipedia
