I used to think it was biro untill i came to know technically it was John j Loud who invented it.He created a pen with a small rotating ball for a nib that was constantly fed by an ink reservoir.Although the pen still leaked and he failed to exploit his patent.
The hungarian Laszlo biro puzzled by the difference in drying times between the newspaper ink and the slow-drying substance in his fountain pen biro and his chemist brother Gyorgy fitted a pen with a small ball -bearing which successfully drew down the printing ink as it rotated.It was first manufactured in 1945 and at the same time biro lincensed his pen to frenchman Marcel bich
Bich called his company Bic the world ballpoint market -leader .Asa respect to biro Argentines celebrate Argentinian Inventors Day on 29 september
