Tap your pick
László Bíró revolutionized writing with his invention of the modern ballpoint pen in the 1930s. He noticed that the ink used in newspaper printing dried quickly and tried to adapt it for pens, leading to the design we use today. Ernő Rubik is famous for inventing the Rubik's Cube, another globally recognized Hungarian invention. Photo: Unknown authorUnknown author, Wikimedia Commons, Public domain.
