WHO IS Ladislao José Biro in Google Doodle Today?

[ferryrinaldi]

Ladislao José Biro was born in Budapest, Hungary in 1899 into a Jewish family. His father’s name was Mózes Mátyás Schweiger and his mother’s name was Janka Ullmann. He had one brother, György Bíró.

He presented the first production of the ballpoint pen at the Budapest International Fair in 1931. While working as a journalist in Hungary, he noticed that the ink used in newspaper printing dried quickly, leaving the paper dry and smudge-free.

In 1943 the brothers moved to Argentina.
On 10 June they filed another patent,
issued in the USA as US Patent 2,390,636,
and formed Biro Pens of Argentina

This new design was licensed for production
in the United Kingdom for supply to Royal Air Force aircrew,
who found they worked much better than fountain pens at high altitude.
In 1945 Marcel Bich bought the patent from Bíró for the pen,
which soon became the main product of his Bic company.
László Bíró died in Buenos Aires, Argentina in 1985.
Argentina's Inventors' Day is celebrated on Bíró's birthday, 29 September.
