Biró

Biró can refer to several things. Most commonly, it is the surname of László Bíró, the Hungarian journalist credited with inventing the modern ballpoint pen. His patent, filed in 1938, described a pen with a rolling ball at the tip that transferred ink from a reservoir to the paper. This invention significantly improved writing by providing a more consistent ink flow and reducing smudging compared to fountain pens. Bíró's ballpoint pen was later manufactured and popularized by companies like Bic and Paper Mate, making it a ubiquitous writing instrument worldwide.

The surname Biró is of Hungarian origin and is a common given name in Hungary, meaning "king" or "lord." It is also found as a surname in other Eastern European countries.

Beyond the inventor, "Biró" might also appear in other contexts, though less frequently. It could be a place name or a term in a specific cultural or historical setting. However, without further context, the association with László Bíró and the ballpoint pen is the most prominent meaning. The pen's design, with its simple yet effective rolling ball mechanism, revolutionized writing for everyday use.
