József Bíró
Ballpoint Pen
- An Argentinian, Biro, while working as a
journalist noticed that the ink used in newspaper printing dried
quickly, leaving the paper dry and smudge-free.
- He tried using the same
ink in a fountain pen but found that it would not flow as it was too
thick. Working with his brother Georg, a chemist, he developed a new
tip consisting of a ball that was free to turn in a socket, and as it
turned it would pick up ink from a cartridge and then roll to deposit
it on the paper.
- Bíró patented the invention in
Paris in 1938.
