History of Ballpoint pen

Who invented Ballpoint pen
The History of Ballpoint Pen can be seen in the 1880s when John Loud was issued the first patent ball pen. The leather tanner tried to make a writing object with which he could write on the leather. The pen which he invented was made in the form of a steel ball rotating at the tip of the socket. John wanted to write it on the leather object. But the letters were not visible or written properly and so, commercially the pen was rejected.
Laszlo Jozsef Biro, a native of Budapest, invented a ballpoint pen, in which he used a ball bearing instead of a nib. He also used instant dried ink that rolled smoothly onto the page and could write for six months, even at high altitudes without being refilled. But this experiment was not successful because the ink was very thick, which took a lot of time to reach the tip of the nib. Hence, he invented a bearing ball nib which was coated with a thin film of ink and when the nib comes in contact with the paper, the ball of nib started moving and obtained the ink from the cartage which helps in fluent writing.
