In our time, a paper clip is the most common item. But in the capital of Norway, Oslo, a five-meter monument is erected on a paper clip. So the grateful Norwegians decided to perpetuate the object, which was invented by their fellow countryman Johann Valer.
Office workers have always puzzled over the question: how to connect paper sheets together so that it does not crumble? For a long time, pins were used for this, which was inconvenient and traumatic.
At the end of the 19th century, the Norwegian mathematician Johann Wahler proposed using curved wire for this purpose. To obtain a patent, Valer even had to go to Germany, since there was no copyright law in his homeland yet. In 1901, Johann Wahler received a document certifying that he was the inventor of the "paleo-clip".
Valer sold the right to make staples to Gem Manufacturing, which soon began producing staples in millions of copies. Many inventors at that time proposed devices for stapling papers, but it was the method proposed by the Norwegian that was recognized as optimal.
At that time, there was a standard: it took 8 centimeters of wire to make one paper clip. Later, paper clips of various shapes and sizes appeared.
In the manufacture of paper clips, both ferrous and non-ferrous metals are used. Staples made of iron are usually coated with a thin layer of nickel. This is to prevent the staples from rusting and ruining the paper. Nowadays, plastic paper clips are very popular.
Johann Valer's invention was used by the Norwegians during World War II: when the country was occupied, the Nazis banned the use of national symbols. Then the Norwegians began attaching paper clips to their clothes as a symbol of national pride.
At the beginning of the article, it was already mentioned that in Norway there is a five-meter monument in the form of a paper clip. But in the Ural city of Miass, the monument is much more impressive - here the height of a paper clip is more than 9 meters. The structure is included in the Guinness Book of Records.
But 40 residents of Singapore got into the Book of Records for being able to assemble a chain from paper clips in 20 hours, the length of which was 15 kilometers and 20 meters.
For the first time, Johann Wahler thought about the idea of creating a paper clip in 1899. 100 years later, Norway celebrated the anniversary of the paper clip and even issued a postage stamp on this occasion.
By the way, the inventor himself at the end of the 19th century experienced serious problems with money. After accidentally seeing a piece of metal wire, he decided to experiment with it to improve his financial affairs.
