1899 – Biro was born on the 29th of September in Budapest, Hungary. Hungarian painter, inventor and journalist.
1938 – While working as a journalist, 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 nib, as it was too viscous. 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.
– Biro patented the invention in Paris, after fleeing anti-Jewish laws in Hungary.
1943 – The brothers moved to Argentina and on June 10th, they filed another patent, and formed Biro Pens of Argentina (in fact, in Argentina the ball pen is known as birome). This new design was licensed by the British, who produced ballpoint pens for Royal Air Force aircrew, who found they worked much better than fountain pens at high altitude.
1985 – He died on 24th of November in Buenos Aires.
– Argentina’s Inventor’s Day is celebrated on Biro’s birthday.
