You may have heard a tale or two about Thomas Crapper, the Victorian-era inventor and sanitary engineer, but there’s a good chance those stories are untrue. So, in honor of Thomas Crapper Day on January 27 (which this year marks the 109th anniversary of his death), we want to set the record straight. Here are five facts about one of the world’s best-known but least-understood plumbers.

1. No, Thomas Crapper did not invent the flush toilet.

The biggest myth about English plumber Thomas Crapper is that he invented the first flush toilet. This would make for an amusing anecdote—"Crapper invented the crapper"—but the fact of the matter is that Crapper wasn’t even alive when the first flush toilet came to be. That dubious honor goes to Sir John Harington (a distant ancestor of Game of Thrones star Kit Harington), who built the toilet in 1596 for his godmother, Queen Elizabeth I. (She reportedly complained it was too loud). According to Snopes, many of the myths surrounding Crapper’s accomplishments stem from the 1969 book Flushed with Pride: The Story of Thomas Crapper, which “has often been dismissed as a complete fabrication.”

2. But Crapper did hold other plumbing patents.

Unless you’re a plumber, you’ve probably never stopped to appreciate the inner workings of a toilet. That little floating valve inside some toilets that prevents tank overflow is called a ballcock, and Crapper did invent that. Altogether, he held nine patents for his inventions, including designs for water closets (early flush toilets), manhole covers, pipe joints, and drain improvements.

3. Crapper plumbed for the British Royalty.

Crapper’s plumbing company was commissioned to do plumbing projects for some pretty high-profile clients, including the people over at Westminster Abbey, Buckingham Palace, Windsor Castle, and the Sandringham Estate. Sadly, any tales that he was knighted by the Queen are untrue.

4. Crapper opened the world’s very first bathroom showroom in 1870.

This is perhaps Crapper’s greatest claim to fame. At a time when it was considered improper to publicly acknowledge bodily functions, Crapper’s Marlboro Works showroom boldly placed functioning toilets on display—and customers could even try them out before buying them. According to Snopes, an article in Plumbing and Mechanical Magazine argued that Crapper “should best be remembered as a merchant of plumbing products, a terrific salesman, and advertising genius.”

5. You can still see Crapper's name on manholes in London.

If you head to Westminster Abbey and look down, you might see a manhole sporting Crapper’s name This is because he re-plumbed the building. According to the Londonist, some original Crapper toilets can also be found around the city—complete with chain-pulls—and a plaque commemorating Crapper’s achievements can be seen outside his former home in the London Borough of Bromley.

How Seiichi Miyake and Tactile Paving Changed the World for Visually Impaired People

More than 140 years after Louis Braille invented the Braille reading system, Seiichi Miyake came up with a different system based on touch that allows visually impaired people to navigate public spaces. Today, tactile paving is used by major cities and transportation services around the world. Miyake was so influential that he's the subject of the Google Doodle for March 18, the 52nd anniversary of tactile paving's debut.

The Japanese inventor designed the influential system with a specific person in mind. His friend was losing his vision, so in 1965, Miyake used his own money to build special mats with raised shapes that lead blind and visually impaired people away from danger and toward safety. Pavement with round bumps was meant to signal nearby danger, such as a street crossing or the edge of a train platform, while a stretch of pavement with straight bars was meant to guide them to safe areas. The tactile design allowed pedestrians to detect the features with canes, guide dogs, or their feet.

Originally called Tenji blocks, the tactile pavement was first installed outside the Okayama School for the Blind in Okayama, Japan in 1967. They quickly spread to larger cities, like Tokyo and Osaka, and within a decade, Miyake's system was mandatory in all Japanese rail stations.

Seiichi Miyake died in 1982 at age 56, but the popularity of his invention has only grown since his death. In the 1990s, the U.S., the UK, and Canada embraced tactile pavement in their cities. Miyake's initial design has been built upon throughout the years; there are now pill-shaped bumps to indicate changes in direction and raised lines running perpendicular to foot traffic to signal upcoming steps. And even though they're often thought of as tools for blind people, the bright colors used in tactile pavement also make them more visible to pedestrians with visual impairments.

Why Are There No Snakes in Ireland?

Legend tells of St. Patrick using the power of his faith to drive all of Ireland’s snakes into the sea. It’s an impressive image, but there’s no way it could have happened.

There never were any snakes in Ireland, partly for the same reason that there are no snakes in Hawaii, Iceland, New Zealand, Greenland, or Antarctica: the Emerald Isle is, well, an island.

Once upon a time, Ireland was connected to a larger landmass. But that time was an ice age that kept the land far too chilly for cold-blooded reptiles. As the ice age ended around 10,000 years ago, glaciers melted, pouring even more cold water into the now-impassable expanse between Ireland and its neighbors.

Other animals, like wild boars, lynx, and brown bears, managed to make it across—as did a single reptile: the common lizard. Snakes, however, missed their chance.

The country’s serpent-free reputation has, somewhat perversely, turned snake ownership into a status symbol. There have been numerous reports of large pet snakes escaping or being released. As of yet, no species has managed to take hold in the wild—a small miracle in itself.
