Thomas Crapper (baptised 28 September 1836; died 27 January 1910) was a plumber who founded Thomas Crapper & Co in London. He was noted for the quality of his products and received several royal warrants.
It has often been claimed in popular culture that the 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".
