Inventors' Day in Argentina Date in the current year: September 29, 2024

Inventors' Day in Argentina Some countries have set aside a special day to recognize the achievements and contributions of inventors and innovators. The date of Inventors' Day varies from country to country. For example, in Argentine it is celebrated on September 29 to honor László Bíró who invented the modern ballpoint pen.

László József Bíró was born in Hungary on September 29, 1899. Working as a newspaper editor, he spent much time filling up fountain pens. He was frustrated by the amount of time he had to waste, so he decide to create a pen using quick-drying viscid ink. Bíró presented his ballpoint pen in Budapest in 1931 and received a European patent in 1938.

When the Second World War began, Bíró and his brother György who had helped him construct the pen fled to Argentina. In 1943, they filed a U.S. patent for the invention. They established Biro Pens of Argentina and started to produce ballpoint pens. One of their major clients was the Royal Air Force of the UK.

Bíró spent the rest of his life in Argentina and died in Buenos Aires in 1985. The next year, his birthday was celebrated as Argentine Inventors' Day for the first time. On this day, Argentinians honor outstanding inventors, scientists, engineers and technologists.
