Flush Toilet
London, England
Alexander Cummings, a Scottish watchmaker, patents the first flush toilet using the S-trap feature which laid the foundation for modern flush toilets. Thomas Crapper added widespread popularity and several refinements to this invention a hundred years later. The flush toilet had a profound impact on public health, allowing residents of cities to transport human wastes (via sewage systems) out of crowded households and city streets.
