Today (5-jul), is celebrated as Mechanical Pencil Day, a day dedicated to honoring the history of mechanical pencils and encouraging people to recognize their diverse uses in our everyday life.
The mechanical pencil was invented by Croatian engineer Slavoljub Penkala in 1906, revolutionizing the way people wrote... His innovation eliminated the need for sharpening, with a mechanism that fed graphite into the pencil as it was used... Penkala, who held numerous patents, designed the first commercially successful model, which quickly gained popularity... His invention not only improved everyday writing but also became a key milestone in the development of modern writing instruments...
