Who was Ladislao José Biro, how did he invent the ballpoint pen and how did it help in World War II?
László József Bíró, was born on 29 September 1899 in Budapest in what was then Austria-Hungary.
He was a sometime journalist, painter and inventor who was frustrated with fountain pens blotting and smudging. He got the idea on a visit to a newspaper printing press, which used quick-drying ink and a roller.
“It got me thinking how this process could be simplified right down to the level of an ordinary pen,” he later said. The rest is history!
