László Bíró's 118th Birthday
Note: Hungarian-Argentinian inventor, who patented the first commercially successful modern ballpoint pen
It was while working as a journalist that he 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 into the tip, as it was too viscous
He presented the first production of the ballpoint pen at the Budapest International Fair in 1931
Working with his brother György, 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
He patented the invention in Paris in 1938
