authentic reproductions of Crapper's original Victorian bathroom fittings. Achievements As the first man to set up public showrooms for displaying sanitary ware, he became known as an advocate of sanitary plumbing, popularising the notion of installation inside people's homes. He also helped refine and develop improvements to existing plumbing and sanitary fittings. As a part of his business he maintained a foundry and metal shop, which enabled him to try out new designs and develop more efficient plumbing solutions. Crapper improved the S-bend trap in 1880. The new U-bend plumbing trap was a significant improvement on the "S" as it could not jam, and unlike the S-bend, it did not have a tendency to dry out and did not need an overflow. The BBC nominated the S-bend as one of the 50 Things That (have) Made the Modern Economy. Crapper held nine patents, three of them for water closet improvements such as the floating ballcock, but none for the flush toilet itself. Crapper's advertisements implied the siphonic flush was his invention. One such advertisement read "Crapper's Valveless Water Waste Preventer (Patent #4,990) One movable part only", even though patent 4990 (for a minor improvement to the water waste preventer) was not his, but that of Albert Giblin in 1898. However, Crapper's nephew, George, did improve the siphon mechanism by which the water flow starts. A patent for this development was awarded in 1897. Origin of the word "crap" It has often been claimed in popular culture that the profane slang term for human bodily waste crap originated with Thomas Crapper because of his association with lavatories. A common version of this story is that American servicemen stationed in England during World War I saw his name on cisterns and used it as army slang, i.e., "I'm going to the crapper". The word crap is actually of Middle English origin and predates its application to bodily waste. Its most likely etymological origin is a combination of two older words: the Dutch krappen (to pluck off, cut off, or separate) and the Old French crappe (siftings, waste or rejected matter, from the medieval Latin crappa). In English, it was used to refer to chaff and also to weeds or other rubbish. Its first recorded application to bodily waste, according to the Oxford English Dictionary, appeared in 1846, 10 years after Crapper was born, under a reference to a crapping ken, or a
