The ball point patent anniversary

June 10 is the anniversary of the patent for the ball point pen filed in Argentina in 1943, but invented in 1938 by brothers László and George Biro. Lázló a Hungarian journalist (September 29, 1899 – November 24, 1985) is considered the inventor of the modern ballpoint pen.

Bíró was born in Budapest, Hungary in 1899. In 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 George, a chemist, he developed a new tip consisting of a ball that was free to turn in a socket, and as it turned would pick up ink from a cartridge and then roll to deposit it on the paper. Bíró patented the invention in Paris in 1938, after fleeing anti-Jewish laws in Hungary.


In 1943 the brothers moved to Argentina and on June 10 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.

In 1950 Marcel Bich bought from Bíró the patent for the pen, which soon became the main product of his Bic Company.
László Bíró died in Buenos Aires in 1985. Argentina’s Inventor’s Day is celebrated on Bíró’s birthday, September 29.
