If you write with a fountain pen, it takes a minute or so for the ink to dry. And unless you are careful, the ink will smudge.
In the 1920s Hungarian journalist Laszlo Jozsef Biro was constantly smudging his interview notes. This really annoyed him.
When walking through the company printing shop one day, Biro noticed that the ink used to run the printing press dried really quickly. He tried putting the quick-drying ink into his fountain pen, but it was too thick. The ink clogged the nib.
Biro didn't give up. He talked to his brother Georg who was a chemist and persuaded him to make thinner ink that dried quickly. When Georg made the new ink, Biro designed a new style of pen.
The biro had a cartridge filled with ink that flowed down a shaft into the tip of the pen. This tip was made of a small ball that turned in a socket. As the ball turned, it picked up ink and rolled it onto the paper.
