He celebrates his birthday every year on April 10 English hairpin, because it was on this day in 1849 that engineer Walter Hunt from America invented a pin, the tip of which is covered with a cap. This design protects a person from a sudden injection.

Why English and not American? The fact is that almost immediately after Hunt, the Englishman Charles Rowley received a patent for a similar pin, which quickly spread around the world.

Things similar to modern hairpins were used even in ancient times. In the Middle Ages, a pin was used to fasten paper.

Now English hairpin is an accessory, an amulet, and a remedy for convulsions, as well as a device for attaching something to clothing (for example, breastplates).
