Thomas Crapper Day is observed on January 27 each year, the anniversary of the death of Thomas Crapper in 1910. Crapper was a successful Victorian plumber in London who helped popularize the flush toilet. Despite a popular myth, he didn't invent the toilet. The day is a lighthearted way to appreciate indoor plumbing, one of the most important public health inventions in history.
History of Thomas Crapper Day
Thomas Crapper was born in Yorkshire, England, in 1836. As a teenager, he moved to London and trained as a plumber. He later founded his own company, Thomas Crapper & Co., and opened a showroom displaying bathroom fixtures, which was unusual at the time. He held several patents, including improvements to drains and the floating ballcock, which refills a toilet tank.
The flush toilet existed long before Crapper. In 1596, Sir John Harington designed a flushing toilet for Queen Elizabeth I. In 1775, Alexander Cumming patented the S-shaped trap, which keeps sewer gases out of homes. In the 1800s, cities built sewer systems, and flush toilets became more common.
It's often said that the slang word 'crap' comes from Thomas Crapper, but the word existed in English long before he was born. Crapper died on January 27, 1910. His company's name on toilets and manhole covers in England may have helped popularize the association.
