Google on Thursday Sep 29,2016 celebrates the 117th Birthday of Ladislao Jose Biro. Many might not know his name but we all certainly know his most famous invention: the ballpoint pen.
14Biro was born, into a Jewish family in Budapest, Hungary , was a journalist by prefession. Biro noticed how efficiently newspapers were printed and how quickly the ink dried - in stark contrast to his fountain pen. He worked with his brother, Gyorgy Biro, to develop a new type of pen made up of a ball that turned in a socket. As the ball turned, it picked up ink from a cartridge and rolled to deposit it on paper, much like a newsprint roller transfers an inked image to paper.
Today's google doodle shows how exactly the 1st ball point pen worked and the mechanism used behind it.
