Who Invented The Ballpen class=

Sagot :


The person who invented the ballpen was László József Bíró, a Hungarian newspaper editor who was so frustrated of the amount of time that he wasted filling up fountain pens and cleaning up smudged pages, noticed that inks used in newspaper printing dried quickly, leaving the paper dry and smudge free. And so he decided to CREATE A PEN using the same type of ink. BIRO asked the help of his brother Gyorgy (a chemist) to develop viscous ink formulas for new ballpoint designs.
