László Bíró

Hungarian inventor (1899–1985)

The first ballpoint pen presented by László Bíró made its public debut at the 1931 Budapest International Fair. Born in 1899 as László József Schweiger, he later adopted the name Bíró. His development of a reliable, smudge-free writing instrument transformed stationery technology and eventually led to the mass production of billions of pens under various licenses.

Early Career and Inspiration

Before achieving international recognition as an inventor, Bíró worked as a journalist in Hungary. While writing for newspapers, he observed that printing ink dried almost immediately upon contact with paper. He attempted to use this ink in a fountain pen but found it too viscous to flow properly. The breakthrough occurred in 1930 while observing children playing with marbles in a puddle; the moisture left behind by the spheres rolling through the water suggested a mechanism for a new type of writing tip.

Technical Development and Patents

Collaborating with his brother György, a chemist, Bíró perfected a design featuring a ball-shaped nib housed within a socket. The rotating ball picked up thick ink from a reservoir and applied it to the paper through capillary action. He secured a patent for this device in Paris in 1938. His design was later instrumental in creating pens for Royal Air Force aircrew during World War II, as the ink did not require gravity to flow properly at high altitudes.

Relocation and Global Commercialization

In 1943, Bíró and his brother fled the Nazis and relocated to Argentina, having been invited by President Agustin Justo. There, they established Biro Pens of Argentina with partner Juan Jorge Meyne. The product became known locally as a birome. By 1945, Marcel Bich acquired the rights to the patent, leading to the creation of the Bic Cristal. While other innovators like Milton Reynolds attempted to circumvent the patent using gravity-fed systems, the capillary design remained the industry standard.

Later Life and Recognition

Bíró married Erzsébet Schick in 1931 in Terézváros, and the couple converted to Lutheranism in 1938. He remained in Buenos Aires until his death on October 24, 1985. His legacy persists in language, as the term 'biro' became a generic name for ballpoint pens in many nations. In 2007, he was posthumously inducted into the National Inventors Hall of Fame, and Argentina marks Inventors' Day on his birthday, September 29.

Fast facts

Questions readers ask

Why is the ballpoint pen called a biro?

The name originates from the surname of László and György Bíró, combined with their business partner Juan Jorge Meyne to form the term birome in Argentina and Uruguay, which later became genericised as biro in many other countries.

What inspired the ballpoint design?

Bíró observed children playing with marbles in a puddle and noticed how the spheres left a consistent trail of water, which he translated into the mechanics of a ball-socket writing tip.
