Who dicovered ball point pen

Answer 1

John J Loud in 1888

Answer 2

The founder / inventor of the ball point pen was László Bíró a Hungarian who presented it at the Budapest International Fair in 1931.

Answer 3

The first patent on a ballpoint pen was issued on 30 October 1888, to John J Loud. The pen had a rotating small steel ball, held in place by a socket. Although the pen could be used to mark rough surfaces such as leather, it proved to be too coarse for letter writing and was not commercially exploited

Answer 4

A Hungarian journalist named Laszlo Biro.

"A Hungarian journalist named Laszlo Biro invented the first ballpoint pen in 1938. Biro had noticed that the type of ink used in newspaper printing dried quickly, leaving the paper dry and smudge-free. He decided to create a pen using the same type of ink. The thicker ink would not flow from a regular pen nib and Biro had to devise a new type of point. He did so by fitting his pen with a tiny ball bearing in its tip. As the pen moved along the paper, the ball rotated picking up ink from the ink cartridge and leaving it on the paper. This principle of the ballpoint pen actually dates back to an 1888 patent owned by John J. Loud for a product to mark leather. However, this patent was commercially unexploited. Laszlo Biro first patented his pen in 1938, and applied for a fresh patent in Argentina on June 10, 1943. (Laszlo Biro and his brother Georg Biro emigrated to Argentina in 1940.) The British Government bought the licensing rights to this patent for the war effort. The British Royal Air Force needed a new type of pen, one that would not leak at higher altitudes in fighter planes as the fountain pen did. Their successful performance for the Air Force brought the Biro pens into the limelight. Laszlo Biro had neglected to get a U.S. patent for his pen and so even with the ending of World War II, another battle was just beginning.."
