Inventor of the ballpoint pen
The inventor journalist László Biro, born in Hungary in 1899 AD, invented the first ballpoint pen in 1938 AD. Biro noticed that the ink that was used in printing newspaper papers dries quickly, so he decided to invent a ballpoint pen based on the same principle. Biro installed a small ball. rotating on the tip of the pen, and as the pen moves on the paper, the ball rotates and leaves the ink on the paper and dries quickly, but this idea has been owned by John Loud since 1888 AD, but he did not exploit it commercially, and Perrault obtained the patent for this idea instead of him, and his pen was used from Before the British Air Force in World War II, he also registered a patent for his invention in many European countries.
Perrault had a brother who worked as a pharmacist named George. He enlisted the help of him and they worked together to develop a new nib that included a free-moving ball that closed and opened to allow ink to pass around it to the port. Whenever the pen moved, the ball rotated and allowed ink to pass from the cartridge around it to the bottom with an even flow.
Today, the ballpoint pen industry has developed into a wide-ranging trade, and the shapes, colors, and configurations have varied, and prices vary from commonly used types to special, distinctive, expensive types used by businessmen and the wealthy as a form of distinction. Some pens have covers made of ivory, gold, diamonds, and other precious metals.
